Arduino Nano RP2040 Connect compatibility #39

Open matemaciek opened 2 years ago

matemaciek commented 2 years ago

Is this fork compatible with Arduino Nano RP2040 Connect? I see that original repo has seperared builds for this board, so I guess I'd need a dedicated build here to?

nope! we use a different pinout - you should stick to arduino's firmware, its very specialized on the rp2040

Thanks for a quick reply! Is it possible to use BLE in CircuitPython via original arduino's firmware?

ladyada commented 2 years ago

no idea :/ you could try it!

matemaciek commented 2 years ago

It looks like it doesn't, or I'm doing something wrong )-:

import board
from adafruit_airlift.esp32 import ESP32
esp32 = ESP32(tx=board.TX, rx=board.RX)
adapter = esp32.start_bluetooth()

results in:

Traceback (most recent call last):
  File "code.py", line 4, in <module>
  File "adafruit_airlift/esp32.py", line 185, in start_bluetooth
_bleio.BluetoothError: Timeout waiting for HCI response

After reading code and schematics it seems that the main problem is that CS and UART RX are on the same pin in Arduino Nano board.
