Make sure that your serial line is 3 line interface. The chip default is 9600, n, 8, 1
I just finished using this chip to make a WIFI interface for an LED sign that I’m going to use on my Christmas light show.
A writeup on the project is at:
There’s a schematic here… wonder what it has on it?
So, where’s my RTFM?
Q2 answered, but not Q1, but more than likely from general ignorance…
I got one of these, and it has 4 contacts at the bottom of the board: VCC/GND, TX/RX… cool, but,
1. If I put 3.3V reg. to the VCC/GND, should one of the LED’s indicate power on? If not, UhOh…
2. The chip wires up power a few different ways for various configurations: AlwaysOn, StandByEnable, DeepSleepEnable, etc… Which way is the shield wired up for?
No public wish lists :(
