Hi All,

Has anyone played with the BT Module inside the dspMIAC?, does anyone have some sample code?

Regards,

Gavin

Hi Gavin,

Assuming you're using Flowcode 8, Please can you try this and let us know how you get on.

Thanks Benj!,

Will give it a go tomorrow..

Hi Benj,

Please see attached Screen Grab of the Set-Up, I assume the Baud rate is 115200?

57600
TX E.4
RX E.3
Flow Control Off

Thanks Leigh,

Still no connection, keeps saying FAIL, I also can't see the BT module in my "search" on my BT Terminal program

Any ideas what else I should check?

Regards,

Gavin

Hi Gavin,
Might be worth just giving the MIAC a test.
Could you load the attached test program using mLoader
On running the program, the MIAC should display the message "MI8759 dsPIC + BT" if all is well and the Bluetooth module has been detected.
Thanks
Leigh

Hi Leigh,

It only says MI5809 dsPIC

F1 for Input Test
F2 for Output Test

No BT

Oh, that's not a good start then
If it was bought as a Bluetooth version MI8759, then it should look like this inside,
the Bluetooth module is on the right between the two white support pillars
To open the unit, pull at the sides slightly to release the top cover catches,
then pull off the top cover whilst pressing on the key pad to push the top pcb out of the cover.

Hi Leigh,

I opened the unit and saw the blue LED flashing on/off every 2-3 seconds. I tried both your code and the one from Benj with the no response from the BT module.

I have ordered any BT Miac so I will wait test that one incase something is no right with the hardware,

Gavin

Also worth checking that the two sets of jumper links are as in the photo

Thanks Leigh,

I did check that as well and all is in order,

Hi,
Here's another Bluetooth test program, this one checks the baud rate.
Leigh

Hi Leigh,

Its working 100%, I also loaded the code from Benj and now it also working,

Thanks allot!,

I would love to see the code the BT Setup..

Gavin

Hi Gavin,
Thanks for the update, glad to hear it is working now
Setup program source attached.
It's an (old) Flowcode V6 program that was written prior to the CAL component property expose changes.
So when you load it into V8 the UART properties will all be incorrect.
I've not got around to fixing all that yet
But if you check and fix the UART properties all should be well
