sony ericsson t23 technical
we are trying to build a project in which we interface an atmel8535 with a sony ericsson T230 by sending AT commands,
we has a successful communication while testing the commands with the hyperterminal and phone,
also our microcontroller supported serial communication with the pc.
however, the Uc and the phone are not being able to establish communication through the C programs we are trying to develop using codevision c compiler.
we have made a testing cable that connects the Uc and mobile, wherein the RTX and TXD connected, ground too, and have shorted the RTS and CTS (is this required?)
it doesnt work this ways...
do we need to give in sum additional voltage for any connections?
also if one guide us in the format of sending the AT commands through the C program... we're really stuck at this stage... would really appreciate sum giudance. thanx...
