Hello everyone,
I’m working on interfacing a GSM cellular phone with computer through AT command. The phone I have is a k300i from sony ericsson.. I managed to interface it with PC and was able to read messages in PDU format. To do this, I used teraterm virtual terminal because I’m using windows 7 and hyperterm didn’t work on my PC. But I made a little mistake. I’ve set the baud rate of the phone with [AT+IPR=*****] command and probably that shut down the auto baud rate detection system of phone.
However it was a week before. Then I got busy with exams and now when I started working again and I discovered that I forgot the baud rate I set a week ago.:roll: I tried with some different values but the interfacing process isn’t working… :sad:
So what should I do now? Is there any way to return this auto baud detect system? Please help.
Thanks in advance.
