CCS/CC2640R2F: Problem with advertising time in aoa_sender project

Hello Kevin,
I asked an expert to take a look at it next week.

Hi,

Can you provide more information regarding this sentence? "We are giving a toggle on the LED1 every packet that arrive, and a toggle on LED0 every AoA packet that arrive (2 packets)."
What are the differences between those 2 indication? Do you mean that LED 1 is when the sender sends a packet?

Are you using PA and LNA signal in the project for toggling?
In the picture above, which one is LED0 which one is LED1?
Please be as detail as possible so we can better assist you.

Hi Christin, thank you for the awnser.

On the photo, the signal 2 (blue one) is every aoa packet that arrive on the receiver. Should be every 100ms.

The signal 1 (yellow) is the combination of 2 packets. On the example of the receiver, it reads frist from one antenna, then switch for the other antenna and use the angle from the antenna with the higher rssi. I belive that work this way. It should be every 200ms.

The problem that I'm having is that instead of the sender send a packet every 100ms, sometimes he sends in a short period.

Thank you.

Can you post your code snippet, I am interested in where you turn on and off the LEDs.
Are you using PA and LNA signal to track the radio activity? If not, can you try it?

Hi Christin,

I'm using all the same configs of the example from aoa_receiver, just added the GPIO_toggle.

Here is the code:

static void AoAReceiver_processAoAEvt(aoaReport_t *aoaReport, uint8_t aoaReportState)
{
  if (aoaReportState == SUCCESS &&
      ((state == BLE_STATE_IDLE_AOA_SCANNING) ||
       (state == BLE_STATE_CONNECTED_AOA_SCANNING)))
  {
#if defined( AOA_STREAM )
    // Treat A1 and A2 the same for now.
    Display_print0(dispHandle, 9, 0, "[");
    for (int i = 0; i < NUM_AOA_SAMPLES; ++i)
    {
        Display_print2(dispHandle, 9, 0, "(%d, %d), ", aoaReport->samples[i].i, aoaReport->samples[i].q);
    }
    Display_print0(dispHandle, 9, 0, "]");

    ICall_free(aoaReport);
    aoaAllocated = false;

    if (AoAReceiver_antA1Result->updated && AoAReceiver_antA2Result->updated)
    {
      AoAReceiver_antA1Result->updated = false;
      AoAReceiver_antA2Result->updated = false;
    }
#else
    uint8_t aoaAdvAddr[6];
    memcpy(aoaAdvAddr, aoaReport->advAddr, 6);

    /*
     * With the I/Q samples stored in `samples` calculate the relative angles
     * for the different pairs of antennas specified in `*curConfig`.
     * -> Result is stored in curConfig->result
     */
    AOA_getPairAngles(aoaReport->channel,
                      aoaReport->antConfig,
                      aoaReport->antResult,
                      aoaReport->samples);

    // The message buffer is quite large (full of AoA samples)
    // We will free it here
    ICall_free(aoaReport);
    aoaAllocated = false;
	GPIO_toggle(Board_GPIO_LED1);
    if (AoAReceiver_antA1Result->updated && AoAReceiver_antA2Result->updated)
    {
	  GPIO_toggle(Board_GPIO_LED0);
      // Print AoA results via UART
      AoAReceiver_displayEstimatedAngle(aoaAdvAddr, AoAReceiver_estimateAngle(AoAReceiver_antA1Result, AoAReceiver_antA2Result));

      AoAReceiver_antA1Result->updated = false;
      AoAReceiver_antA2Result->updated = false;
    }
#endif // AOA_STREAM
  }
  else if (aoaReportState == MSG_BUFFER_NOT_AVAIL)
  {
    Display_print0(dispHandle, 3, 0, "AoA Out of Memory!");
  }

  // We still need to deallocate the buffer even if the AoA event
  // was not successful
  if (aoaAllocated == true)
  {
    ICall_free(aoaReport);
    aoaAllocated = false;
  }

  // If we are in non-connected AoA, always start a new scan
  if (state == BLE_STATE_IDLE_AOA_SCANNING && aoaIdleScanStarted)
  {
    AoAReceiver_aoaStart();
  }
}
