I have a problem when I tried to send a sms message.
I have downloaded the ‘Ping_GPRS’ sample application to the hardware and I send AT command via the hyper terminal.
AT commands that I’ve tried are:
(1) AT+CMGS="+6421xxxxxxx" (NZ vodafone).
(2) > test!!! (ctrl+z)
I am getting ERROR, looks like the message never got sent.
