Bluetooth connection

Hexy Questions, Problems and Suggestions
#1

I am having problems with the Bluetooth connection.

I am using Win7 and Servotor32 2.0. I followed the instructions from the following page:
https://github.com/ArcBotics/Hexy/wiki/Bluetooth-Win7-Tutorial

I got to the “… successfully added to this computer” screen and show connected through COM 18.

When I ran PoCoMo it would not connect. I ran a serial terminal and the red light on the module stopped blinking, but I could not get a response to the AT command.

Found the Win7 trouble shooting further down the page, but I can’t find ServotorComm.py to make the edit.

Just to make sure I pulled the Bluetooth module and plugged in with USB cable and ran PoCoMo agian, that works just fine.

Has the ServotorComm.py file name changed? Or if anyone has an idea, let me know.

Thanks in advance!

What AT command are you talking about?

I’m also having issues with my bluetooth.

I’ve tried uninstalling/reinstalling the bluetooth drivers. I’ve tried connecting to it via pomoco, the Arduino Serial Monitor and putty. I’ve also tried communicating to it from Mac OSX and Win 7 64-bit.

I can connect to the module (the light stops blinking and goes solid) but I cannot send or receive from it.

Any other ideas I can try?

@distantcam: can you see what com port its on? There’s a section on how to do that at the bottom of the windows bluetooth tutorial.

As suggested by @roboalchemist in an email, resetting the board with the bluetooth module in it has done the trick. I’m not sure what that did but it worked.

The board took a long time to reset. The status light on the board was pulsing for a long time, then blinked on and off as it does at startup of the Servotor firmware.

Anyway it’s working for me now.

How do you reset the board?

#7

Press the reset button in the middle of the board.

The problem I’ve been experiencing is that my Mac will pair with the Bluetooth module (blinking red light; Mac says paired), but I cannot open a connection from PoMoCo.py.
When I run the command

serial.Serial(port, baudrate= BAUD_RATE, timeout=2)

manually, it complains that the Bluetooth port is busy. I’ve run lsof and fuser and don’t see any process using the Bluetooth port. I power cycled the Mac to see if that helped - no joy.

Anyone else have this problem? Any fixes to report?
I’ll try the board reset when I get home.

I am having the same issue. Running Mountain Lion - it says I am paired, but the light stays flashing and PoMoCo doesn’t find the Servotor.

Resetting the board did the trick for me!

I notice the Hexy moves MUCH slower over bluetooth. Is this due to it being set to 9600 by default?

#11

Resetting the PoCoMo board with Bluetooth plugged in worked for me.
I didn’t notice anything happening when I pushed the reset - just pushed for 5-10 seconds - the Bluetooth module was pulsing red.
No change. Went to my Mac and tried using PoCoMo.py and it connected. Joy!

Servotor32 reset with BT module plugged in was also the solution for me (communicating with it via an Ubuntu lappy). Needed a minor code mod in servotorComm.py, which is a bit of a hack currently. Will try to make it a bit neater and post.

#13

I did find the ServotorComm.py file and made the adjustment suggested towards the bottom of the BT setup
https://github.com/ArcBotics/Hexy/wiki/Bluetooth

I also reset the main board while the BT is plugged it.

When I run PoCoMO I still get the message - unable to connect to Servotor.

Using win 7, Servotor32 2.0. Windows shows the BT has paired and is on COM 18.
The BT light blinks all the time, other than when I open a Serial terminal on COM 18 at 9600 and then it is steady.

Are there any other trouble shooting tips I can try?

I am also having problems with using PoMoCo via bluetooth

I am on Win8 64bit
I can connect to the bluetooth module assigns it COM 40
the light on the bluetooth model is a steady red

PoMoCo still will not find my Hexy :frowning:

already tried resetting the board and forcing python to run under admin rights so far nothing has worked

help would be much appreciated

I found another bluetooth module I had from a previous project. Swapped out the modules and every thing works now!

Put the ArcBotics one back in, same old problems.

I have always wanted a Hex-a-pod but at $600-800 for a cheap one I didn’t see it happening.

Thank you Arcbotics for finding a way to sell a Hex-a-pod at in a price range I could reach!
