I recently build the arduino-o-phone and it works great. I can also run the FONAtest program with good results. I'm using a FONA 800.
However, when I try to run Incomingcall or Open_sesame, I get this result:

Couldn't find FONA
There are no "OK" responses. The difference in the programs is this:
// Note that this is different from FONAtest!
#define FONA_RX 3
#define FONA_TX 4
#define FONA_RST 5
#define FONA_RI_INTERRUPT 0
I tried switching from a Metro to a Uno and no difference. I also tried with and without the fona RI connected to digital 2.
I need some help with this.
Thanks, LR
"Couldn't find FONA".....in some cases
