M5StickCPlus Bluetooth and Arduino Uno with HC05

  • I am trying to get the M5StickCPlus to talk to an Arduino Uno via the HC05 Bluetooth adapter, and I can't get them to connect.

    For the M5StickCPlus I'm using BluetoothSerial.h to set up the connection via BluetoothSerial.connect(<Name or Address>) - but it doesn't work with either name or address.

    I've tried changing the AT commands on the HC05 to make it automatically pair with the M5StickC, but that doesn't work either.

    I can, of course, connect to both via Android.

    Any thoughts on how to make this pairing work?
