Hi Electro-tech-online. I am back to ask help again about my newest project. The project is all about using a mobile phone as a substitute for RF Transceiver Modules. The user should be able to control some appliances using only mobile phones. When the user sends a text message by his mobile phone to another phone, the other phone will then check the data received. The mobile phone then sends command to the microcontroller to do such task. I don't have problem with programming the microcontroller since I already know it. I am still searching informations about AT commands since I think AT commands will be mostly utilized.
The first thing I have thought was to try if everything works on my desktop computer. I would try first connecting the UART pins of the mobile phone to a MAX232 to be connected to the Computer. Through hyperterminal, I will send data then the mobile phone should respond properly.
I don't know yet the cheapest mobile phone that has a UART tx, rx and gnd pin. Perhaps 8210? or what else do you think? I am thinking also what if I'll use mobile phones which has the USB cable then I'll just cut them and find which one is the tx, rx and gnd pin. Can you add more some tips on how to build this project? Any replies will be much appreciated![Big Grin :D :D](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
