Using a Atmega328P based NANO.
Only got to play with the ESP8266 for a little bit. Its the "black" version with "AI-Cloud" stamped on it.
I think I had it almost working last night, but with the wrong baud rate as I was getting garbage chars in the serial monitor.
I was using the 3.3v supply from the Nano, but it seems some say to use the 5v supply and regulate it to 3.3v to the ESP.
I've seen quite a few diagrams now for this, with and without regulators, with and without resistors.
Does anyone have a definitive diagram that should be used with the NANO to insure proper stability of the ESP8266?
Also, my networks are locked down to MAC address have to be in my list.
Is there a way to grab the MAC address of the module without being connected to a network? I did not see that as a command to be able to send?
