RN1100 trouble


I’m using the RN1100 expansion card on a project and it has mysteriously stopped working.
All of the digital outputs are held high even though the sample program appears to run and toggle the bits on the screen.
The RN1100 red LED does not come on until I toggle one of the digital outputs
on the PC side.

If I run the digital input sample code the RN1100 LED turns on but none of the digital inputs will toggle when I toggle the switch connected to it.

Does any one know what the problem could be or is the board just toast?

Thanks for any help you can provide.

The problem ended up being the BL2600 not talking to the RN1100.
I swapped out the BL2600 and all is fine.
