I have been trying to get the wt32i to communicate as either a cell phone or a headset that will automatically link to a remote headset of unknown type so that I can communicate with it.
I need a basic command set to get this going. I can add enhancements later.
for this operation you can use HFP and A2DP profile. For more information about those profiles please check following application notes:
In general if you want to use a WT32i as a headset you need to configure it as:
HFP and A2DP sink
on the other hand if you want to use it as a cell phone you need to configure it as
HFP-AG and A2DP source.
Also, please keep in mind that to be able to recognize the device correctly you need to set correct class of device.
