in the last year I've been developing solutions for ESP01 and ESP12.. at the beginning with Arduino IDE, then I switched to NodeMCU.
I'm dissatisfied by both. Each one has pro&cons, the ideal would be something with the sum the pros
Are there reasonable alternatives?
What I want to achieve is to create a platform where all my sensors are connecting to a backend on a regular basis to check for the firmware updates. If it detects an new firmware, it has to download, update itself and restart. Each sensor has to support mqtts and a number of probes.
