Dear all,
how are you?
I'm working with sim300 and AT commands.
I want to connect GPRS and send a message to host via tcp/ip by AT Command only
I use Hyper Termial, i tried some commands but unsuccessful.
i can access internet with that sim card by GPRS, but i can't do with SIM300.
Could you please help me steps by steps what should i do?
i tried this:
atd*99***1#
NO CARRIER
AT+CGATT=1
Sometimes return OK, sometimes ERROR, sometime it halt(nothing and can't enter any command)
Please help me about this, Thanks alot.
