how to use arduino usb host shield and bluetooth dongle

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 test code for sending keystrokes from arduino Through trial and error i found that the following HEX codes correspond with the following keys strokes on a Mac OSX: 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. Using Sparkfun’s Bluetooth Modem – BlueSMiRF HID to interface between an Arduino Pro Mini and a desktop Computer as an Human Interface Device (HID).
