I tried to change the bluetooth default password 1234, according to the manual Coleman gave me, but no luck.

I used COM6 and baud 38400 setting to connect to my rover arduino. but as u can imagine, this serial communication is connected to the arduino chip, but not the bluetooth module. The manual is not clear about how exactly to connect to it. Please help.

Manual:
CuteDigi BMX Bluetooth to UART/I2C/USB Module (GEN II)

Steps to configure the module as master device:

  1. PIO11 is set to high.
  2. Power on, and the module will enter into AT command mode.
  3. Use hyper terminal or other serial console, set baud rate 38400, data 8 bit, stop bit 1, no parity,
    no flow control.
  4. Send “AT+ROLE=1\r\n”, if successful, it will return “OK\r\n”.
  5. PIO is set to low, and power cycle, the module will be master device and automatically search
    for slave device and do binding.

We have contacted the manufacturer to hopefully give you a foolproof procedure. They will either reply here or we’ll transfer their reply.
