Hi everyone,
i'm playing with SIM900 (firmware version 1137B07SIM900M64_ST)
The module works fine, i power on the module and after 10/20 seconds the network is registered and fully operative.
But if i loose signal (i disconnect the antenna for example) the module takes 2/3 minute or more to reconnet to the network.
Any suggestion ?

Thank you.
 

Do you mean that when you disconnect antenna module looses signal and then when you reconnect the antenna with module already powered on it takes 2-3mins to register.?
If YES: I guess this is normal. Mine too takes about a min or two in that scenario. I think its in the module's firmware. It checks for network at high rate when it turns on and once it gets registered, it slows down the rate. That's just a guess, i am not sure about this.

Yes that's what i mean... i think too that it's related to firmware, but i'd experience with other modem and never had this beaviour.
