RN-XV connection help

Somewhat frustrated here because it seems like connecting to the RN-XV should be very straightforward - but nothing I have tried has worked.

This is what I have:

I’ve tried connecting to the RN-XV via the FTDI basic board (https://www.sparkfun.com/products/9716) that I have - I cut the connection between the 5v pad and soldered up the connection to the 3.3v pad - I confirmed with a DMM that the connection was broken and that 3.3v was produced.

Hooking the RN-XV up to the FTDI board (soldered jumper wires on the RN-XV plugged in to the sockets on the FTDI) resulted in no LEDs lighting on the RNXV, and when I entered $$$ in teraterm to get in to the RN-XVs setup utility, I did not received a CMD response as listed in the manual.

I re-tried this configuration using the 3.3v output of my arduino board - thinking that maybe the FTDI couldn’t pass as much current as the RN-XV needed - still no response.

I then gave the ADHOC mode a shot - soldering a wire between the 3.3v power and pin 8. In this configuration, LED D1 lit up solid - but I could not find the allegedly generated network on either my PC laptop or iphone.

I’m about fresh out of ideas for getting this to work - maybe its defective? Any help regarding troubeshooting, setup, etc would be greatly appreciated.

Forgot to mention that the FTDI TX LED lights up when I try to send signals to the RN-XV via TeraTerm, so it seems that there isn’t an issue there . . .

I will try to help, but I need more info.

Hook up 3.3v and ground only on the wifly. What does the green led do? Slow blink?

Nope, no LEDs light in that state. Only led I could get to light was D1 when 3.3v was piggybacked to pin 8 to enable adhoc. Any thoughts?

Thanks,

Chris

Best guess is fried, sorry. I’ve got an RN-XV in front of me, and if I restore to factory defaults I get the slow green blink (which is the Idle indicator) and an intermittent red blink (which it does every time it fails to join a network, as the default is auto-join). If you’re not seeing that, and you are certain the power and ground pins are correct, it is an ex-Wifly.
