#76906 I 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:
Code: Select all0,CONNECT

+IPD,0,4:�␁␁�
+IPD,0,4:�␁␀�0,CLOSED



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 :shock:


Now I am a little bit less a newbe, the strick was to define the UART rate at 9600 bauds, and all was sloved :D
