You say “there is a hardware issue”, could you please be more specific? I’d like to understand why it is not possible on POI when it is working on other IDEs.
I’m also curious… I don’t know much about ‘actual’ debugging on the ESP8266 (as opposed to the Arduino littering of serial print statements) and am wondering if PIO can somehow take advantage of esp-gdbstub to do debugging… although limited to one hardware breakpoint and one hardware watchpoint… the issue of software breakpoins only working for code in RAM, and the hardware breakpoint only working for code on flash… and the WiFi stack causing the whole thing to crash if the cpu is stopped for too long… er… I think it’s probably a whole disaster just waiting to happen. But it will sill be nice!
