Hi guys,
I've interface L80 GPS and M95 GSM module with PIC microcontroller. Our intention is to make it work like vehicle tracker. We have wrote http protocol in it and make it communicate with our http API server. I want the modem to work flawless after switch ON. What are the preliminary check of the modem before going to http process? We have collected two preliminary check like whether sim is registered or not, sim signal strength, other than these is there any other checks?

Thanks
 

Try to send some data from the GSM modem to some known number and try to receive some data
 

hello


on GSM M95 (QUECTEL ?)
after global init :
* STAT must be =1 (status of power ON)
* NET info must blink

GSM must give response when sending "AT" command =>"OK" means UART speed OK
send PIN code "1234" ?
and test presence of network

Code: 
20:01:44.125>  Test si enregistré sur le reseau (AT+CREG?)     // send AT cde
20:01:46.625> 
20:01:46.687> +CREG: 0,5   // answer form GSM
20:01:46.687> 
20:01:46.687> OK   // answer from GSM
