CC2652R: PER measurement

Takayuki Miyazaki

Part Number: CC2652R

Hi Experts,

Our customer is creating code for PER measurement For current their code, customer obtains event-data after HCI_EXT_PacketErrorRateCmd() is executed, as follows.

Since customer was not able to find how to get data after HCI_EXT_PacketErrorRateCmd() is executed, they are referring SDK source code. However, customer is not sure what those parameters(nPkts, nCrcErr, nEvents nMissedEvents) mean. Could you clarify them, please?

              static void ble_VsCmdCompleteEvt (hciEvt_VSCmdComplete_t *pMsg)
              {
                  switch (pMsg->cmdOpcode)
                  {
                  case HCI_EXT_PER:
                            
                          uint16_t nPkts         = BUILD_UINT16(pMsg->pEventParam[4],  pMsg->pEventParam[5]);
                          uint16_t nCrcErr       = BUILD_UINT16(pMsg->pEventParam[6],  pMsg->pEventParam[7]);
                          uint16_t nEvents       = BUILD_UINT16(pMsg->pEventParam[8],  pMsg->pEventParam[9]);
                          uint16_t nMissedEvents = BUILD_UINT16(pMsg->pEventParam[10], pMsg->pEventParam[11]);

And then, it would be appreciated if you will share helpful document/URL for this.

Best regards,

Hi Miyazaki,

The best way to find details on the Vendor Specific HCI commands (such as HCI_EXT_PacketErrorRateCmd) is to consult the TI Vendor Specific HCI Guide. There you will read "When this command has completed, an HCI_EXT_PER event shall be generated.". Still using the TI Vendor Specific HCI Guide you can look for the description of the HCI_EXT_PER event and understand the different fields of it.

In the BLE Stack User's Guide we have a section explaining how to handle the TI Vendor Specific HCI Commands.

I hope this will help,

Kind regards,
