I can't connect to Azure IoT Hub -> Timed out waiting for SPI char

[SyntaxWarrior]

Im using an Arduino Nano RP2040 Connect .

I have this firmware: adafruit-circuitpython-arduino_nano_rp2040_connect-sv-7.0.0 I have these libs: adafruit-circuitpython-bundle-7.x-mpy-20211116

I keep getting this error: Timed out waiting for SPI char

Full debug log from my little program (keys have been edited along with urls).

I'm new to the whole MicroPython / Arduino scene, so I hope I'm just doing something simple wrong. Would appreciate any help.

The solution was to upgrade the Nina Wifi firmware as explained here:

Glad you got it working!
