I want to know what is the temperature range  BT HCI module(BL6450CQ automotive)  can be  normal operation behavior.

I did‘t find  min temperature  info from BL6450CQ DS only max temperature 85°...

could you tell me where is be written？

    Hi,

    The temperature range for this device is -40C to 85C. If you look on page 14 for BT Transmitter – EDR characteristics the table shows the  performance characteristics over the temperature range.

    Best regards,

    Vihang

    Hi Vihang

          Thank you,I see。

          Sorry I want to ask another question，OK？

         I want to test the performance of BQB  certification test  RF receive sensitivity and so on.

        I know that had to go into  the test mode to fix frequency when BQB test etc. 

        I got the CC256x HCI API commands from shanghai TI FAE，

        But How can I use  these commands（Sorry I don't understand these CMD for what can these CMDs do）

       when I require the software to make a test mode version for hardware design verificate performance.

       for example, If I want to test the Buletooth recieve sensitivity in fix frequency mode,  

       I think  I could just inform software design to use  the HCI_VS_DRPb_Tester_Con_RX (0xFD17)  CMD,is it right?

       if want to test the transmitter sensitivity, so could just inform software design to use         HCI_VS_DRPb_Tester_Con_RX (0xFD17) command ,right?

      please check it thank you.

    For receiver sensitivity measurements, you will need to use a Bluetooth tester like CBT and configure the controller in the BT RF SIG Testing mode.

    Reference : http://processors.wiki.ti.com/index.php/CC256x_Testing_Guide#BT_RF_SIG_Mode

    The sensitivity for each modulation type can be measure in this test mode using the CBT test equipment.
