I have about a dozen ESP8266 modules.
I just received one that when it is powered, the red light does not come on. Nor will it show up in any available networks list such as on my cell phone that shows all available WiFi networks.
It is the ONLY ESP8266 I have that does this. EVERY other one will have the red light come on once it's powered.
When I contacted the seler, they said it was fine and the seller sent me some files and documentation but they are direct from China and I'm hesitant to open them.
Is it usual for some ESP8266's red LED to NOT come one when powered?
