    smartbridge signal level specification

    bshaya

      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

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

            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[s], 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.
