Last updated 1 year ago

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

  • 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 for exact settings for your Operating System)

  • Turn on HID Mode. More info . 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 (slide the switch).

  • Finally - update the relaykeys.cfg file with

      baud = 115200
      

(Or whatever speed you so wish)
