Communicate via SMS from a cellphone with a microcontroller
Posted on 2003-03-18
Is it possible that you can give me some information on how
do go about with the following:
What components do one use to go about for the above design.I would like to use a Nokia phone (61 or 30 series) to do the above interfacing.Is it possible that you can tell me where I can get the AT commands for the Nokia
I would like if you can inform me on the specifications and protocol to use to communicate or control via Short Message Service(SMS) on the cellular phone with a microcontroller.
I would like to control I/O via a cellphone (e.g. switch LEDs or relays via SMS with my cellphone).
Because phone company usually treat SMS packets as VERY VERY LOW PRIORITY.In the worst case, the message may take more than 24 hours to arrive. For the best performance, I would like to make a normal voice call and use DTMF to encode your messages.
Is it possible that you can give me information on the above
I would appreaciate it if you can give me some info and support .
Thanx in advance
