I’m a newbie programmer working on a project using esp32 that reads some data like temperature, current and voltage. This data is sent to an MQTT broker. The problem i’m facing is the following: When i first uploaded my firmware a few months, everything worked pretty well. But when i updated the firmware via mDash the device lose its connection. MQTT keeps receiving data but mDash never reconects, even if i reboot the device. I tried to use older versions but it worked the same way. What could it be? A problem in the network i’m using or something like that?
thanks in advance
