Hi everyone, looks like a LOT of confusion with this board, and VERY LITTLE good info online as far as I have found.
I managed to get it working, I can upload sketches to the Mega with switches 3 and 4 on, and upload sketches to the ESP with 5, 6, and 7 on...
With 1, 2, 3, and 4 on, I can upload sketches to the Mega, and the Mega and ESP can talk over serial (Mega-Serial3, ESP-Serial)
So I've got a WebServer running on the ESP, as well as loaded a MySQL connector library so it can read/write data to a remote MySQL Server.
The Mega will connect using SoftwareSerial with 3 other Pro-Mini's, each with 8 sensors (limit of analog pins) and send results via Serial3 to the ESP which will parse the data, and do inserts into the database.
The WebServer can then read this data and display it...
I'm concerned that all this DIP Switch switching is going to kill the tiny little switch!
There is also the MODE button, which existing instructions say you must push to program the ESP. Well, I can program the ESP with the proper DIP Switch settings, and don't need the MODE button. In fact, if I have the DIP Switches in another configuration, the MODE button doesn't do anything.... I'm hoping it's a shortcut so you don't need to keep changing the DIP switches all the time during development...
Some actual instruction here would help, do you just press it and release at any time? press and hold during upload? Press and hold at bootup? Tried em all, nothing....
I've only had this for a couple days,. and I like it, and will be ordering more, but I sure hate the thought of it becoming useless over a mangled dip switch....
