Bluetooth Module Issues. Anybody have similar problems?

Hi guys,

It's me again. :D

This time I have taken the step of installing the robobuilder bluetooth module into my robot. I am intending to use the bluetooth module in conjunction with my custom C firmware.

However, I have run into a roadblock. Now, whenever I press the red square button on the remote, my robot goes into a spasm, repeating the same motion, over and over again.

This has not happened before I installed the bluetooth module. The only way I could stop this spasm, is to connect my robot through HyperTerminal, then press the red square, after which, it would perform two actions, then stop it's movements. It would then be able to respond normally.

Here is the readings from HyperTerminal.

"OK

CONNECT 00 Special event [0000]
0:0:44-686 Do Motion 0000
11 Special event [000B]0:0:45-795 Do Motion 000B
675ED4AA
q0:1:8-547 Do motion 0013?"

Any brother or sister here encounter the same issues as I did?

I would greatly appreciate it if you guys would point out to me what could be the potential issue at hand here.

Cheerios! :D

Hi - I have seen this before - the BT module seems to send a Modem style CONNECT string that the firmware picks up, reads and interprets as issued commands. Its put you into experimental mode. and then done motion commands. I think you need to configure your BT to stop sending the string.

I'm not developing this firmware - instead I'm concentrating on developing DCMP for remote control, and Basic http://code.google.com/p/robobuilderlib/wiki/Basic and http://code.google.com/p/robobuilderlib/wiki/Femto Femto for autonomous control.

cheers

Thank you for your input!

Would you mind pointing out to me, what needs to be changed on the module? I am clueless.. :wink:

If it is of any help, I am using the robobuilder Bluetooth module, preprogrammed to run in mode 3 and 115200 baud rate.

I would greatly appreciate your guidance!

Hopefully, this would not hinder my interest in my robot.. haha!

I don't think its at the robobuilder end as I have the same module and didn't have to make any changes to its set up.

I think its your bluetooth driver on your laptop/PC. It thinks its talking to a modem rather than a serial port.

good luck
