Cheap WiFi modules

Also, If you are trying to use Putty (terminal program) from your PC and some sort of usb.ftdi serial converter (caution!! 3v3 only) to communicate serially you have to enter CTRL+J to get the thing to take your command.

If you switch to something like "Termie.exe" it works without the CTRL+J.

Apparently putty has a problem properly sending either the carrage return or the line feed.

Also when using the CWJAP command you have to include the quote marks " when you enter your AP credentials.

I bought one of these off of amazon and it came configured to 9600 baud out of the box.

NOTE: another way to deal with the 3v3 requirment is to just power your PIC and the ESP module from a single lithium ion battery. No 3v3 to 5v0 converter needed

Question... how sensitive to over voltage is the 3v3 type devices? If I take my single lithium ion battery off the charger it usually has around 3.8 to 4.0v is that going to be destructive??
