The PIO documentation regarding this Heltec board infers (doesn’t it?) that debugging using PIO is possible. I believe this is not the case because GPIO14 is used to reset the integrated OLED., and GPIO15 is SCL for the OLED. I don’t think it is possible to re-assign these pins is it?
Can anyone confirm there is not a simple workaround please?
If it is not suitable for debugging then maybe the docs should be a little more explicit so folks know not to buy this system if they want to debug?
