adisonnvc WROTE:yes, it work well when using hyperterminal but not working when interface with pic. is that because of different type of gsm modem that i use?
shahrul WROTE:I never heard any different GSM protocol other than AT Command. Just look at the interface, it is RS232 or TTL or USB. But most I heard, still use AT Command.
robosang WROTE:AT command is just a method of sending and receiving the command and data from a device. With AT command there are still different set of "protocol", for example XBee is using AT command too, but can the AT command set from GSM be used on XBee?
