Hi,
ive been reading through the troubleshooting tips for the Wifly shield and i believe most of the posts assume that you are able to start the Wifly. I saw one post saying there was a problem with the pin connection and was solved by making sure the contact was there.
if the Wifly cant even be BEGUN (all tools hang when executing Wifly.begin()) what are the steps to make to be sure that the soldering is good or even the chip itself is working. What would be the test points? are there specific continuity points to check with a tester just to make this quick?
thanks for the help

Well, first off you must ensure that the Wifly is getting powered. This means that it should be getting 5V through the Vin pin on the Arduino, and should be connected to Ground. After this, the module should start blinking the orange and green LEDs.
Also, pins 10 through 13 are used for communication between the Arduino and the Wifly module, so these should be checked as well for conductivity.
A good way to check these is to upload sparkfun’s example code, which checks if the Bridge is OK. If so, this might infer that the pins are connected correctly.
I believe these are the first steps towards checking if the Wifly is working…
