Is it possible to play with the built-in Bluetooth(and BLE) on the esp32 on Pico Wireless pack?
So the shop page says that you can use Adafruit’s CircuitPython library with the board if you’re running CircuityPython on the Pico (rather than Pimoroni’s MicroPython firmware). Adafruit’s guide page has a section on running BLE on ESP32 co-processors, so it should be possible via CircuitPython. Theoretically, that means the ESP32 can recieve the commands to turn on BLE with MicroPython too, but you’ll probably have to figure out the API and implement that manually, as I don’t see it in Pimoroni’s MP firmware. It might just be easier to use CircuitPython.
