@anujdeshpande does it crash if you scan with nothing attached? I.e. a factory RPi Pico?

@Bucknalla

Bucknalla commented 7 months ago

@anujdeshpande so it sounds like a zephyr issue?

anujdeshpande commented 7 months ago

@Bucknalla I think I am going to just setup an arduino real quick. Have a working setup with Adafruits official library. I just want to ensure that I have working hardware before debugging zephyr further.

(This might come in handy later too)
