Hi,

Is there any reference AT-commands library written in C for SPWF01 modules? Googling didn't help. Target OS is FreeRTOS, but generic C library is acceptable.
I know, I can write it using state machines etc. It will take time. I believe many of you have already implemented something related.
I would also glad to hear any clues on generic AT-commands libraries which could be easily extended for this module.
They should support at least following functionality:
- data and command states
- async status messages from modem

Could also somebody answer two additional questions:
- if there any status messages while module is in data mode? So, should I check RX buffer in data mode for something like "+WIND:"?
- what happens in case of closed socket on remote end or lost network? Will module return to command mode itself?

Answer to these additional questions would help in implementing own state machine.

Thank you.
