Bluegiga WT32 dual SCO connection

Hi all,

I am new to the Sparkfun Forum, so please excuse my first post. :smiley:

I have been experimenting with the wonderful Bluegiga WT32 module.

My requirements are Seria Data, PIO control lines, full duplex audio left and right channel all to work without a host.

Although iWrap 4 is neutral in this matter, I have discovered a method to obtain 2 x SCO connections with a successfull link up. Although the method is no ideal, the initial experiment proved it can be done with a minor bug that I feel needs to be cleared by Bluegiga.

I am not able to get to the bottom on how to trigger Connect 1 SCO and Connect 2 SCO connections automatically , and would like to call upon others for advise/ideas on this matter.

Below is a SET screen dump. At the bottom are both SCO connections with 2 x full duplex audio.

It is acheived by manually toggling/forcing GPIO-7 (80H) via a pull-up resistor, but only after initiating a command line “Set Control Autocall 1” and you have to wait for Connect 0 rfcomm1 event to show.

The question is, has anyone acheived full autocall Connect 1 SCO and Connect 2 SCO???

Regards

Gerald
