Could not connect to the network.
Hi Sir, I have tried the main.cpp of Seed_GRPS_Shield. I could not connect to the network.
The way i connect is: p9(TX) of mbed to D0(RX) of Seeed Studio GPRS Shield V2.0 and p10(RX) of mbed to D1(TX) of Seeed Studio GPRS Shield V2.0.
VU of(5.0v USB Out) Mbed to VIN of GPRS Shield, and GND to GND.
I used Starhub MaxMobile Prepaid Card. (https://www.starhub.com/business/support/internet-ip-solutions/faqs/prepaid-mobile-broadband.html)
I print out in putty terminal and it printed as follow:
Could not connect to network. Retrying!
May I know what would be the problems?
Thank you so much:D
