I’m developing a datalogger, and I need to send some data from a Form widget to my device that is via MQTT. My device is an ESP32 and i’m connecting it using GPRS network. I already made the upstream part, but the downstream is making me very confused. Could someone send me examples or show me some way to implement downstream?
There is a thread about this Light a LED in ESP32 - Devices & Connectors - TagoIO Community. Please, follow the same thread and add your questions to it if you have any.
