Hi, all,
I am testing on my own MC35i GSM/GPRS embedded modem pcb. It is working from power up meaning that I can send and receive sms through the modem. But after minutes (sometimes hours), it just hang there with the led indication same as 'initialization'. But it returns 'sim not inserted' error when i tried to send an sms. I have checked the schematics and PCB layout, but can not spot any mistake.
Has anyone encounter same situation b4?
Thanks.
