GY-521 MPU-6050 6DOF 3-Axis Acceleration Gyroscope Module.Prototype with Breadboard Shield for Arduino UNO.Micro USB 4.5V-5.5V 1A Lithium Lipo Battery Charger Module.18650 Lithium Battery Charging Module Protection.It also have an option to clear the remote address, as there isn’t a way (that I can see) to clear the pairing on the RN42 end. It it has been paired then the connection is established. If the device isn’t yet paired the remote address is empty so the connect fails. My RN42 keyboard and joystick implementation tries connecting (C command) with the remote address on power up. Unlike windows the iPhone actually has an option to connect to any BT device including HID keyboards, so auto connect from the keyboard isn’t required. Since HID BT devices like keyboards and joystick come and go Windows passively waits for them to initiate the connection.

For serial BT devices Windows will activly make a connection to serial devices whenever the device is opened, for example in a terminal emulator.
Bluetooth allows either end to connect once paired, but Windows has some conventions. So after power up the problem is that there is no connection, and by pairing again you are forciing a re-connection (step 3 above). Pairing only needs to be done once and does essentially three things…ġ) The RN42 adds the host to a hidden pairing table of up to 8 hostsĢ) The RN42 sets it’s remote address to the hosts address (which you can see with the GR command) It doesn’t work as a mouse or joystick.Ĭonnecting after loss of power – This isn’t a problem with pairing. There is even a command to pop up the keyboard on the iPhone. IOS recognition – Works great as a keyboard. For this to happen the Arduino needs to put the Bluetooth modem into command mode ($$$) and send the following commands: The Bluetooth modem can switch back and forth between an HID device and a device with a serial port connection (SPP mode).
Do you wish to remove the pairing and setup the device again?” I have to go back into the Bluetooth preferences and opt to add a new device, then select “Okay” when asked “Your computer is already paired with that device. When i disconnect the Bluetooth modem from the power, my computer does not automatically re-connect to it when i re-power it. – now that your Bluetooth modem has been recognized as a keyboard you want to quickly open a text editor and it should automatically be printing “hello world” “Hello World” – it will try to identify the circuit as a keyboard, press a button on your real (other) keyboard and the next step will let you skip the step and manually input the type of keyboard you want the circuit to be recognized as – The light on your BlueSmirf Modem should turn a steady green – opt to connect with passcode, and type “1234”, which is the generic passcode – the circuit should show up as a FireFly Bluetooth device with an address similar to this: 00-06-66-43-A2-29 – open the Bluetooth preferences of your computer and opt to pair with a new Bluetooth device – power your circuit and the light on your Bluetooth modem should blink red Serial.println(“hello world”) // write hello world Serial.begin(115200) // begin serial communication at 115200 baud rate

Universal Serial Bus (USB) HID Usage Tables > Īrduino as a HID Keyboard code by Andrew McDaniel (did not work for me with BlueSmirf Bluetooth modem!) > topic=99.0įor whatever reason the ASCII Codes-HID Report Tables are missing from Roving Network’s RN-HID-UM user manual on page 12. Some useful info on the Sparkfun product page’s comments section > I am still trying to figure out if there is also a standard way to SEND signals TO the HID Bluetooth modem to trigger events, such as force feedback…Īlso see the Penguin Interface project > ĭownload Roving Network’s RN-HID-UM manual >
The default mode of the BlueSMiRF HID is as a keyboard (which is very easy to set up), but you can also use it in HID raw mode (see user manual) to send keyboard, mouse, joystick combos.
