Thanks for your support Hendrik
Actually I’m porting paho-mqtt as MQTT client (not the sn). Had a lot of issues using native, so I was thinking to verify it works with an ESP32. The issue I had yesterday was that my board is an ESP32-CAM (chinese clon) and the board is not defined in RIOT, so I started to porting this board as well but have not much knowledgement with ESP32 wroom and wrover (kindy a confuse me a bit) and its features. Do you have any repo where you commited your ESP code, even if it’s with paho mqtt-sn?
if you don’t mind I would need some help. Can I contact you directly?
Thanks, have a good day to you all
