This would return ERROR_SERVICE_NOT_ACTIVE if the stack has not been
initialized yet. For this API, if pConnections is too small to contain the
buffer it should return ERROR_INSUFFICIENT_BUFFER.
In any case, this is not the best API for you to use. You want to call
BthGetHardwareStatus - see PB Help.
This API will tell you:
- Stack is down, hardware is not present
- Stack is down, but hardware is present
- Stack is up and running
Plus a few other states - See PB Help for details.
If you want to know if there are currently baseband connections present
then you should also call BthGetBasebandConnections (or
BthGetBasebandHandles). If the stack is up and running this API should
return successfully. Make sure you call the API with a large enough buffer
to store the resulting data.
I hope this helps.

|

-
| does not work
|
| if (pConnections > 0) tells me that it is connected - works
| else it is not connected - works
|
| The return value is ERROR_SUCCESS even when the device is powered off!
|
| Am I doing something wrong?
|
| Any idea how I can determine if the device is not on and connected via HCI
| to the stack?
|
| Why am I not getting the expected return value?
|
| Thanks.
