Bluetooth Apps, NFC, Android Beam, S Beam





Definitions

"Bluetooth" is a wireless technology which allows smartphones to transfer data over short distances (e.g. from your phone to your headset, or between two phones across a room).

"NFC" ("Near Field Communication") is a wireless technology which allows smartphones to transfer data over extremely short distances (usually no more than a few centimeters).

"Android Beam" uses NFC to establish a Bluetooth connection between two smartphones for transferring photos, web links, contacts, YouTube videos, etc.

"S Beam" is Samsung's extension of Android Beam. It uses NFC to establish a WiFi Direct connection for faster data transfer (up to 10 times faster than Android Beam).



Transferring Files Using NFC

To use NFC and Android Beam (or S Beam) for transferring a photo from Phone A to Phone B, do the following:

  1. On both phones, turn on NFC (in the Settings menu). Bluetooth does not need to be turned on.
  2. Bring up the photo on Phone A.
  3. Hold both phones back-to-back so they're touching (or nearly touching). You'll hear a sound when the NFC connection is made. With tablets, you'll need to move the devices around until the NFC chips in both devices find each other.
  4. On Phone A, you should see a "Touch to beam" message. Tap the photo, and you'll hear a "success" sound or a "failure" sound. If the process is successful then the notifications area on Phone B will show that the download is in progress (the phones can now be separated up to about halfway across a room).
  5. When the download is finished, Phone B will make a sound, and you can tap the "Beam Complete" notification on Phone B to see the photo.
The same process works for transferring web links, contacts, YouTube videos, and so on. However, sometimes it's finicky and doesn't want to work. For example, I've been able to transfer photos from a Samsung phone (which has S Beam) to a non-Samsung phone (which has Android Beam), but not from the non-Samsung phone to the Samsung phone (both phones were running Android 4.1.1). I wasn't able to transfer a photo from an Android 4.0.4 phone (which has Android Beam) to an Android 4.1.1 phone (which has Android Beam), but the transfer worked fine when the Android 4.0.4 phone was upgraded to 4.1.1.



Pairing Two Bluetooth Devices

In order to use Bluetooth for communicating between two smartphones (or other devices), first the smartphones must be "paired" by following these steps:

  1. On both phones, go to the Settings menu.
  2. On both phones, turn on Bluetooth, then tap "Bluetooth." This brings up a screen which shows the name of the phone (e.g. "HTC One X") plus a list of devices that the phone has been paired with (if any).
  3. On each phone, tap its name (e.g. "HTC One X"). This will make each phone visible to all nearby Bluetooth devices for about two minutes.
  4. On one phone, tap "Scan" or "Search for devices" (it might be in the menu). When the other phone shows up in the list, tap it.
  5. Read the message, then tap "Pair" on both phones. The phones are now paired.
When two devices are paired with each other, you don't need to go through this process the next time you want to communicate between them over Bluetooth.



Android Bluetooth Apps

App developers sometimes add or change or remove features, so there might be slight discrepancies between my descriptions (below) and the current versions of some apps.


Blobby Volleyball by AppsOn (free) - A cute volleyball game which can be played against a Bot (the computer) or against a human opponent over Bluetooth or WiFi (I haven't tried the WiFi option). In the single-player game, select the Bot's skill level (in Mirror mode you control both players, and Angry mode seems to make the Bot highly skilled). You control the red blob on the left by sliding your finger left and right in the slider area below the blob. To make the blob jump, slide your finger above the slider area, or tap the "up arrow" icon at the bottom right corner of the screen (the controls can be changed in the Options menu). To play against a human opponent over Bluetooth, turn on Bluetooth in the Settings menu on both phones and then do the following:

  • On both phones, tap "Bluetooth."
  • On one phone, tap "Become discoverable" on the "Host game" tab, then tap "Yes" to make your phone discoverable by other phones for 90 seconds.
  • On the other phone, tap the "Join game" tab, then tap the name of the host phone in the list of paired phones.



Bluetooth chess by Haksoft (free) - Play chess against a human opponent on the same phone or against a human opponent over Bluetooth. To play, tap a piece and then tap its new location. To play against a human opponent over Bluetooth, turn on Bluetooth in the Settings menu on both phones and then do the following:

  • On both phones, tap the "2 players by Bluetooth" button.
  • On one phone, tap "1P White." On the other phone, tap "2P Black."
  • On the "1P White" phone, tap the "Make discoverable" button, then tap "Yes" to make your phone discoverable by other phones for 300 seconds.
  • On the "2P Black" phone, tap the name of the "1P White" phone in the list of paired phones.
  • On the "1P White" phone, tap a time limit for the game.



Bluetooth Holdem Poker FREE by Ilumnis (free) - This is an offline Texas Hold'em poker game. For single-player poker, enter your name, and how many "bots" (computer opponents) to play against, and your initial cash amount, and the "small blind" amount (the default bet for the player to the dealer's left), then tap the "Start New Table" button. Other human players can join you via Bluetooth, so the game will wait for them to join. If you're not playing against human opponents then tap the screen to continue. After the cards are dealt, a small white circle next to a player's cards indicates who the dealer is. The player to the dealer's left automatically places the "small blind" bet, and the next player to the left automatically places the "big blind" bet (twice as much as the "small blind" bet). When it's your turn to play, tap the "Check," "Call," "Raise," or "Fold" buttons at the bottom of the screen (if you don't do anything for 30 seconds then you'll automatically fold). To play against human opponents over Bluetooth, turn on Bluetooth in the Settings menu on all phones and then do the following:

  • On each phone, tap the "Multiplayer Poker" button.
  • On one phone, tap the "Start New Table" button and fill out the information, then tap "Yes" to allow the phone to be discoverable by other phones.
  • On the other phones, tap the "Join Table" button and fill out the information, then tap the "Join Table" button, then tap the name of the phone which is hosting the game.
  • When all phones are connected, the player who started the new table needs to tap his/her screen to accept the connections.



Carrom 3D by Zagmoid (free) - A carrom game (similar to pool) which can be played against the computer or against a human opponent on the same phone or against a human opponent over Bluetooth. The board contains nine white disks and nine black discs, plus one red disk (the "queen"), which are all gathered in the center of the board before the first shot. The object is to use the large white "striker" disk to knock all of your colored disks into a pocket (the scoreboard at the top of the screen indicates which player is which color), plus knocking the "queen" into a pocket. Before the first shot of the game, Player 1 can rotate the disks at the center of the screen. To shoot, slide the white striker left or right to line up your shot (or double-tap where you want the striker to be). Double-tap the striker to turn it yellow. Now tap the striker and drag your finger to prepare to shoot. A white arrow will show the direction in which the striker will move (the longer the arrow, the more force will be applied to the striker). Lift up your finger to shoot the striker into the disks (to cancel the shot, drag your finger back to the striker until you see a red "X"). To change the viewing angle, drag the board left and right or up and down. If you tap the center of the board and then drag left and right, this will move the board. To zoom in/out, double-tap the board or use pinch-to-zoom. You're allowed to knock the queen into a pocket at any time (as long as you still have disks on the board), but you must cover it with one of your disks on the next shot, otherwise the queen is placed at the center of the board. To play against a human opponent over Bluetooth, turn on Bluetooth in the Settings menu on both phones and then do the following:

  • On both phones, tap the "Play" button.
  • On both phones, tap the "Settings" button, then tap the "Network Game" button, then tap "Play Using Bluetooth," then tap the "Close" button.
  • On one phone, tap the "Manage Players" button. If your name or your opponent's name doesn't appear in the list then type in your name and select "Human" as the Type, then tap the "Add" button. Type in your Bluetooth opponent's name, then select "Network" as the Type, then tap the "Add" button. Tap the "Close" button, then tap the "Back" button. Select your name for Player 1, then select your Bluetooth opponent's name for Player 2. In the list of paired devices, tap your opponent's device and then tap the "Invite" button.
  • On the other phone, tap the "Accept" button within 60 seconds.



Connect Five by WeHe Development (free) - Play Five in a Row against the computer or against a human opponent on the same phone or against a human opponent over Bluetooth. To play against a human opponent over Bluetooth, turn on Bluetooth in the Settings menu on both phones and then do the following:

  • On both phones, tap "Bluetooth."
  • On one phone, tap the "Make device discoverable" button at the bottom of the screen, then tap "Yes" to make the phone discoverable by other phones for 120 seconds.
  • On the other phone, tap the name of the opponent's phone in the list of paired devices.



Free Cards by Destruction Industries (free) - Provides a deck of cards which allows two human players to play virtually any card games against each other over Bluetooth. When you want to play a card game with someone but you don't have a deck of cards, this app might come in handy. To play a card game, turn on Bluetooth in the Settings menu on both phones, then do the following:

  • On one phone, tap the "Options" button in the Free Cards app and set the appropriate options (such as entering a name and a number of cards to be dealt), then tap "OK," then tap the "Host Game" button.
  • On the other phone, tap the "Options" button and enter a name and tap "OK," then tap the "Join Game" button, then tap the name of the paired phone which is hosting the game.
If the hosting person selected a certain number of cards to be dealt (in the "Options" menu), then each person will see his/her cards at the bottom of the screen, and a green area at the top of the screen. The green area is shared between the two phones, meaning that both players can see what happens in the green area. Drag cards from the deck, and double-tap cards to turn them over. Drag a rectangular selection box around some cards to highlight them. The highlighted cards can be moved as a group, or they can be turned over as a group, or you can long-press a highlighted card to stack the cards neatly side-by-side. Tap anywhere outside of the highlighted cards to unhighlight them. To return to the Main Menu, go to the menu and tap "Exit Game." One drawback of the app is that players are free to take as many cards from the deck as they want, at any time, so you must use the honor system and play fair (the developer told me that he's addressing this issue).



MultiMaze by Lundi Software (free) - Play a maze game by yourself or against a human opponent over Bluetooth. In the one-player game, you must guide the yellow ball from its starting position in the top left corner to the goal at the bottom right corner. Tap the arrows in the center of the screen to move the ball. When the ball is touching a ladder, tap the small circle at the center of the screen to go down the ladder, then tap up, down, left, or right in the large circle at the center of the screen to move the ball through the dark underground tunnel to another ladder, then tap the small circle to go up the ladder. In the two-player game, both yellow balls begin in the top left corner, and both players race to the goal. To play against a human opponent over Bluetooth, turn on Bluetooth in the Settings menu on both phones and then do the following:

  • On both phones, tap the "MultiPlayer" button.
  • On one phone, tap the "Start Bluetooth Game" button. Enter your name in the "Player Name" field (you can keep the default in the "Game Name" field), then tap the "Start Game" button. Tap "Yes" to make your phone discoverable by other phones for 300 seconds.
  • On the other phone, tap the "Join Bluetooth Game" button, then enter your name, then tap the "Join Game" button, then tap the name of your opponent's phone in the list of paired devices.



Sea Battle 2 by BYRIL (free) - A Battleship game which can be played like the classic Battleship game, or it can be played using ships, planes, anti-aircraft canons, and mines. For a one-player game, tap the "Player vs. Android" button, then select Advanced mode (to play using ships, planes, anti-aircraft canons, and mines) or Classic mode. In either mode, on the next screen you can drag your ships onto the grid, or tap the "Auto" button to have the ships placed randomly for you. To rotate a ship on the grid, tap it and then tap the "curved arrows" button. When all of your ships have been placed onto the grid, tap the "Next" button. In Advanced mode, you have a certain amount of money to spend on planes, anti-aircraft canons, and mines. Drag a plane onto the grid, and one row of the grid will turn blue (which indicates where the plane will fly during the game). Move the plane up or down to select the desired row, then lift up your finger. Drag a cannon onto the grid, and two rows of the grid will turn purple (which indicates where the cannon will shoot during the game). Move the cannon up or down to select the desired rows, then lift up your finger. Drag a mine to an empty grid cell. When finished, tap the "Play" button. To play, tap an empty grid cell on the right side of the screen. If you miss, you'll see your artillery shell floating in the water where you tapped. If you hit your opponent's ship, you'll see a red "x" where you tapped, and you get to try again. If your opponent had placed a mine where you tapped then it will blow up the same grid cell on your grid. To use a plane, tap the "plane" icon (nothing will happen if you tap the "cannon" icon). A plane will fly across the row which you had selected for your first plane (if you fly a second plane then it will fly across the row which you had selected for your second plane, and so on). When a plane flies across a row then one of three things will happen: 1. If your opponent had placed an anti-aircraft cannon which covers that row then your plane will start smoking and it won't be able to drop a torpedo (an anti-aircraft cannon can only shoot down one plane). 2. The plane will drop a torpedo in that row, which will hit the first ship that it comes to (and you get to play again). 3. If there are no ships in that row then you'll see a floating artillery shell (i.e. a "miss") in every cell of that row. To play against a human opponent on the same phone, tap the "Player1 vs. Player2" button. Player 1 places the ships, then taps "Next," then places the planes, canons, and mines, then taps "Next," then Player 2 does the same. The arrow at the top of the screen indicates that Player 1 plays by tapping the empty grid on the right (which is labeled "Player2"). Player 1 uses a plane by tapping the "plane" icon on the left (above the grid labeled "Player1"). To play against a human opponent over Bluetooth, turn on Bluetooth in the Settings menu on both phones and then do the following:

  • On both phones, tap the "Bluetooth Battle" button.
  • On one phone, tap the "Show Me" button, then tap "Yes" to make the phone discoverable by other phones for 300 seconds.
  • On the other phone, tap the "Scan" button, then tap the name of the phone in the list of paired phones.



Spit by GoodSoft (free) - This is a "Spit" or "Speed" card game, which can be played against the AI (the computer) or against a human opponent over Bluetooth. After the cards are dealt, you can arrange your piles of cards by tapping a card (to highlight it) and then tapping another card which has the same value (e.g. place a 3 on top of another 3, and place a Q on top of another Q). Tap a face-down card to turn it over. When all of your face-up cards are unique, you're ready to play. Tap your face-down stack on the left just above your cards, and then one card from your stack will be placed into the play area (your opponent needs to tap his/her face-down stack to place a card into the play area). If the value of one of your face-up cards is one higher or one lower than either card in the play area then quickly tap your card and then tap the card in the play area (which will move your card to the play area). After you place a card onto the play area, it will usually reveal a face-down card under it. Tap the face-down card to turn it over, and arrange your piles of cards as you did at the beginning of the game. After you place a card onto the play area, it might leave you with an empty stack. You can move any card onto the empty stack. When you can't make a play, and your opponent can't make a play, then you each need to tap your face-down stack. This will display an arrow pointing to your stack (until the other person taps his/her stack), and you won't be able to move any cards to the play area while there's an arrow pointing to your stack. The goal is to get rid of all of your cards before your opponent does. To play against a human opponent over Bluetooth, turn on Bluetooth in the Settings menu on both phones and then do the following:

  • On both phones, tap the "gear" icon (the middle icon at the bottom of the screen) to go to the Options menu, then tap "Opponent," then tap "Bluetooth." Tap "Player Name" and enter your name, then tap your phone's Back button twice to return to the green screen with a deck of cards.
  • On one phone, tap the "curved arrow" icon at the bottom left corner of the screen, then tap "Yes" to restart the game. Select "Dealer," then tap the "OK" button.
  • On the other phone, select "Non-Dealer," then tap the "OK" button, then tap the name of the opponent's phone in the list of paired devices, then tap the "Connect" button.
