I have one question…
I have several ESP 8266 esp01 version ,attached to arduino uno and arduino mega.
These system comunicate with external devices with MQTT protocol, (knolleary PubSub library).
My question is very simple…If you have the same hardware, also your blue led on the ESP8266 continously flicker ???
I dont understand why the led flicker… (during night time is a little bit annoing)
Ah …the system works …seems only strange to me these kind of behaviour … I can’t find any video on the net to compare
