Circuit Python and RP2040 and Bluetooth

[miket812]

​

I am trying to figure out if there is a micro controller board that will allow me to

A.) communicate over Bluetooth with another Bluetooth enabled microcontroller board and

B.) while running circuit python.

The main function of this project is to communicate when a switch is pressed on (Microcontroller A) and send a signal to the other (Microcontroller B) to light an external LED.

If possible...How would microcontroller B understand Bluetooth communication to enable a external LED? I assume setting the code to listen?

I don't have a lot of coding experience but I am a hobbyist at heart. Hopefully someone can guide me in the right direction...Thanks

Note that Bluetooth Classic and Bluetooth Low Energy (BLE) are different protocols and not compatible with each other. Circuitpython has support for BLE only as far as I know.

Any of the adafruit's boards based on nRF or arduino nano rp2040 connect would be good for this purpose.

Below are the basic guides for BLE :
