Bluefruit LE Friend

Although it should work - and we promise you it did work - something has broken functionality working with the LE friend. So we aren't officially supporting this right now

• Install the CP2104 Driver

• Update it to 0.8.1. Easiest way to do this is to connect to using the Bluefruit app - it will auto-update it if required.

• Plug it in

• Set the switch on the device to CMD mode

• Open up a serial terminal and connect to the device (See here for exact settings for your Operating System)

• Turn on HID Mode. More info here. To be precise - enter this into your serial terminal

    AT+BLEHIDEN=1
  
    ATZ 

(You should see 'OK' after each entry)

• Next change the default speed. i.e. enter this in your serial terminal:

    AT+BAUDRATE=115200

• Next put the device into DATA mode (slide the switch).

• Finally - update the relaykeys.cfg file with

    baud = 115200
    

(Or whatever speed you so wish)
