I'm using AUBTM 20 module for bluetooth communication with PC in SPP.... For this I pair the Module with PC and then open the corresponding Com port in PC which results in a communication between the two..... Now the problem is how do I disconnect the module from PC ?.. If I disconnect terminal in PC side I am not able to reconnect again.....It shows CANNOT OPEN COM 5.... neither the module responds to any AT Commands from...... actually I think the module hangs....please can anyone help me regarding the same.... Thanks in advance
hi soham would you please tell me how to communicate through AUBTM-20 Bluetooth module from PC? i am connecting my BT module to pc using UART. it gives OK. but when i entered any command is not responding. please help me
Hi tahertinu,
After connecting Bluetooth to PC with UART, open Hyperterminal, select the COM port, Baudrate(9600)..
Do the Hyperterminal settings ie. File-->Properties-->Settings-->ASCII setup (check the image attached).

Now you powerup the Bluetooth it should respond OK,then send LLL enter(Receive OK),send AT enter(Receive OK),send AT? enter which lists all the AT commands..
Any doubt comeback...
i have done this still not responding. please tell me what can be the reason for this?
Only properties changes i made then it started working...actually if all these are done then should work..
when you connect is it giving OK after you type LLL & enter..till what step it is working...
it shows OK but it is not responding to any ATcommands. please give me solution

Hello shree4u,
If you receiving OK after LLL its fine, after this you should give ENTER before typing any command (Ex. AT, AT+MODE) & after typing also ENTER command is required...you may be missing out this...try it once...
