FONA 3G and I2C interface

Post by flore »

Hello everybody,

Is there anyone who manage to use the FONA 3G I2C interface?
I try to connect one MMA8452 accelerometer.

The command AT+CRIIC=0x1D,0x0D,1 return ERROR.
I try the logic analyzer function from PICKIT and shows NO activity on SCL or SDA pins.

The only refference found in the documentation are the read and write commands, no other configuration options.
Can anyone test with an oscilloscope the activity on this pins?
I am really confused.

Thank you.
