Microsoft bluetooth stack multiple instances

Question

Hello Everyone,

I am having a problem in using two Bluetooth adapters on Microsoft Bluetooth Stack. Either of the adapter works fine until other adapter is not connected. When other adapter is connected it does not starts shown in Device Manager. Reason, displayed is Device cannot start(error code 10).

I think it is due to resource conflict link Audio service which may be resolved if multiple instances of Microsoft Bluetooth Stack could be run or by some configuration setting. I am struggling for long but still I have not found any working method.

Bluetooth Adapter: Atheros 3011.

Error with second device:

Hi Suresh,

Only one active Bluetooth radio is supported at a time in Microsoft Bluetooth Stack. It should be possible to make connection to a few destinations at the same time using one radio. No stack on Windows supports more than one radio.

For further assistance on this issue, I would suggest you to post your query in TechNet Forums.
