a0 01 01 a2 command well received but inoperante
Posted: Fri Jul 06, 2018 3:16 pmI have two esp8266 equipping each a 5V relay PCB, one is working like a charm on any of the relay PCB.
The other seems working well wrt. AT commands: connect fine with my wifi AP and here starts the mistery for me:
This last one (whatever the relay PCB) refuses to activate the relay, here-below what I captured on the serial line when the magic packets (close and then open) is sent via wifi:
I forgot to say that I am a newbe with esp8266, but I sure you saw it at the fisrt line...
any help will save several nights of good sleep for me
Now I am a little bit less a newbe, the strick was to define the UART rate at 9600 bauds, and all was sloved
