    How to achive packet counter when test BT RX characteristics,how to reset this counter

    mili_2550941

      Dear All:

           Our product has a WIFI/BT combo module,which use BCM43353 as main processor,and we need test RF characteristics of the product.

      When test BT RX characteristics,we need check if received packet number is same as transmit packet number of SG .So we need achive this packet counter,and reset this counter to next step.

       

           Our supplyer provide 3 file for test: "test, TL.INI, bcm43353bt.hcd".but they told us can't get this counter.

       

           We want know:How to achive packet counter when test BT RX characteristics and how to reset this counter. Any HCI Command can support our requirement?

       

      Thanks!

          Hi,

           

          LE_Test_End command results in an event with the number of packets received. Please refer to section 10.2 of attached document.

          Please check if this helps your requirement.

           

          Thanks,

          Anjana

            Dear Anjana:

                 We run receiving test accroding to section 9.2.2, but nothing received. Test log as below:

            微信图片_20190924134152.png

            Accroding to "Bluetooth Controller then reports statistic data in every 1000 ms to the Host Processor", we should receive data every 1 second.

             

            Can you give us some suggesstion?

             

            Thanks!

              Hi li min,

               

              The RX_test will not start printing any results until it has started receiving correctly formatted test packets.

              If the RX_Test doesn't print any results, then it is likely a configuration issue on the transmitter side.

               

              I have a working setup on my side where I start a TX_test on one board and an RX_test on the other board. I used WICED SDK mbt tool for test.

               

              1. First start Tx test on one board . Or in your setup start tx test first

              2. Now start rx test on the test board.

              Now you should be able to get the packets printed.

               

              Attached is my test result for rx test.

               

              Thanks,

              Anjana

                Dear Anjana:

                     Good news. We can receive statistic data when test as you mentioned.But we don't know the define of each byte,can you send me this definition?

                 

                Thanks!

                  Hi li min,

                   

                  Do you mean you don't know how to decode the statistic data received?

                  If then, I am sorry, not sure where to point out you for the reference.

                  However I can guide you as per test console which I am using.

                   

                  I am using mbt tool (provided along with WICED SDK .Available in WICED installation folder here: C:\Users\.....\Documents\WICED-Studio-6.x\wiced_tools\mbt )

                  Below is how the statistic report is decoded :

                    printf("Statistics Report received:\n");

                          HexDump(in_buffer, dwRead);

                   

                   

                          if ((dwRead == 35) && (in_buffer[0] == 0xFF) && (in_buffer[1] == 0x21) && (in_buffer[2] == 0x07))

                          {

                              printf("  [Rx Test statistics]\n");

                              printf("    Sync_Timeout_Count:     0x%x\n",in_buffer[3]  | in_buffer[4] << 8  | in_buffer[5] << 16  | in_buffer[6]  << 24);

                              printf("    HEC_Error_Count:        0x%x\n",in_buffer[7]  | in_buffer[8] << 8  | in_buffer[9] << 16  | in_buffer[10] << 24);

                              printf("    Total_Received_Packets: 0x%x\n",in_buffer[11] | in_buffer[12] << 8 | in_buffer[13] << 16 | in_buffer[14] << 24);

                              printf("    Good_Packets:           0x%x\n",in_buffer[15] | in_buffer[16] << 8 | in_buffer[17] << 16 | in_buffer[18] << 24);

                              printf("    CRC_Error_Packets:      0x%x\n",in_buffer[19] | in_buffer[20] << 8 | in_buffer[21] << 16 | in_buffer[22] << 24);

                              printf("    Total_Received_Bits:    0x%x\n",in_buffer[23] | in_buffer[24] << 8 | in_buffer[25] << 16 | in_buffer[26] << 24);

                              printf("    Good_Bits:              0x%x\n",in_buffer[27] | in_buffer[28] << 8 | in_buffer[29] << 16 | in_buffer[30] << 24);

                              printf("    Error_Bits:             0x%x\n",in_buffer[31] | in_buffer[32] << 8 | in_buffer[33] << 16 | in_buffer[34] << 24);

                          }
