In some Telit modules there is a software ready (SW_RDY) line which indicates the host controller about the readiness of accepting the AT commands, so is there any way to idendify that the module(ME910-C1) is up and ready to accept AT command?
Dear Krishna Kishore,
there is any SW_RDY line. You have to follow the flow chart showing the proper turn on procedure at page 34 of the ME910 HW User Guide.
Yes i have gone through the power on flow sequence, do you mean to say that SW_RDY is not available in this module and PWRMON is the only one signal we need to rely on?
Yes the PWRMON pin indicates when the module is powered ON. Then you have to wait the correct timing to start sending AT commands.
