I bought a MR60BHA2 and I am able to get it into Home Assistant via ESPHome (it arrived flashed in this way). I want to develop my own sampling / publishing solution and thought to go via Arduino, following the examples and adapting them.
I can compile and upload the code, no issue, but then I see nothing on the Serial monitor and I cannot even run the blink example. I tried several solutions and eventually thought that maybe the issue is the Serial, but everything works (I tried the WiFi example but nothing connects to the WiFi …) … but no.
I am sure I am making a stupid mistake somewhere, but I am not finding a way out of the corner. I succeded in re-flashing back the provided seeed-studio firmware to get the thing work with HA and ESPHome, but this is not what I want … I am making my own platform and I need to be able to program access to WIFI and MQTT …
Is anyone able to help? Thanks in advance.
