guruflorida on CEL-10138 - ADH8066 GSM Module

I found this module to be one of the easiest to setup and get working, I used the breakout board, but not the eval board. 1. I used a bench power supply with 2x 330uF caps plus 1x 47uF caps all in parallel and on the module side (so as to provide low impedance power to the module). 2. Tied DSR0 to GND. 3. Wired an FT232 breakout module into GND, RX0 and TX0. 4. Used the AT&T SIM card from my iphone. It’s a micro-sim but I lined it up and it still worked. 4. Wired a switch from ONKEY to GND (basically a power enable) 5. Connected Putty to COMx with 115200 8N1, No flow control (otherwise default putty settings) Followed the samples in the Software Development Guide and I was calling phones and sending text messages. Note: The manuals always put 09 in front of the numbers (both voice and text) but this must be a non-NA thing. Here in the US simply use an AT command something like: (refer to SW Dev Guide for full example.) ATD5558675309;
