Hi,
Does anyone have any STM32 C code for programming the SIM900. The code I've written uses interrupts but receives a lot of rubbish back in response from the modem. I continually send AT, and then it initially responds with AT. I would have been expecting OK.
When I send further commands it replies with rubbish "1818181E9E60" (hex values of the returned characters)
I'd really appreciate any help.
Thank You
Bob
