Since I got a Bittle kit + Sensor pack I have 2 Petoi Bluetooth adapters.
I wanted to use one for Nybble and changed the baudrate to 57600 using AT commands.
Worked as described in the manual.
Works with Nybble using the Arduino Serial Monitor connected to the Bluetooth port.
However now it is not responding to AT commands when not connected via Bluetooth (flashing red led on the module).
How do I get the module to respond to AT commands?
Hi, you can connect it to the USB programmer for NyBoard. Then you can use the wired serial to set the commands.
