We are trying to debug a custom design involving a bluetooth smartbridge module (USI BM-GP-BR-65). Is it possible to get the signal level specification for communication with the smartbridge, or at least the signal sequence that should occur when wiced_bt_init is called?

Thanks,

Ben

As far as the current single chip BCM4334x based SmartBridge Wi-Fi + BT solution which is included within SDK 3.0.1, it looks a lot like the previous version which uses a 2-chip solution. 

So while both BLE and BT Classic are supported on  both the current and past SmartBridge solutions, simultaneous support for a dual mode stack is NOT.

Here's the rundown on our current SmartBridge offering:

1.

Currently supported on WICED-SDK-2.4.1:
BCM20702
-GATT (not-simultaneously with SPP)
-SPP/RFCOMM

2.
Currently supported on WICED-SDK-3.0.1:

2a.
BCM20702
-GATT (not-simultaneously with SPP)
-SPP/RFCOMM

2b.
BCM43341
-GATT

3.
Future support for a dual-mode stack with simultaneous SPP and GATT support is definitely on the roadmap, but I cannot provide an ETA on when this will be released.

Apparently the module is simply an HCI-compliant controller.  Funny that broadcomm advertised these as working together well with the wifi modules...
