Confused about polling interval

[Unitware]

I have been studying the power consumption of a prototype and observe that the end device is polling very frequently.

The data request polling is backing off for a while to about every 3 seconds, but suddenly (efter 15 seconds or so) the device starts polling every 200 ms or so. 

If I disable the turbo polling mode then the polling will be every 500ms from start.

I'm wondering if you can help me put with some pointers to there I should start looking. 
My goal is to poll once every ten seconds or so, and maybe a increased polling rate after any device activity to fetch pending commands.  

My project is based on the multiprotocol doorlock example in sdk 4.0.0 and I am using SDK 16.0 to fill in the gaps to make it compile. Changes that I have meade includes moving the application out of the sdk-directory structure and I am using make and gcc to build it.

Hi,

Sorry for the late reply. The default value for long poll interval is 5 seconds. To change the data polling intervall you need to use zb_zdo_pim_set_long_poll_interval(zb_time_t ms).

Best regards,

I'd be happy even with the default value but it is not working. the interval is 280ms after 15s.

When can I use the function call? I have done it in the callback when network is joined:

```

void zboss_signal_handler(zb_bufid_t bufid)
{
zb_zdo_app_signal_hdr_t * p_sg_p = NULL;
zb_zdo_app_signal_type_t sig = zb_get_app_signal(bufid, &p_sg_p);
zb_ret_t status = ZB_GET_APP_SIGNAL_STATUS(bufid);
zb_ret_t zb_err_code;

/* Update network status LED */
zigbee_led_status_update(bufid, ZIGBEE_NETWORK_STATE_LED);

switch(sig)
{
case ZB_BDB_SIGNAL_DEVICE_REBOOT:
/* fall-through */
case ZB_BDB_SIGNAL_STEERING:
if (status == RET_OK)
{
zb_ext_pan_id_t extended_pan_id;
char ieee_addr_buf[17] = {0};
int addr_len;

zb_get_extended_pan_id(extended_pan_id);
addr_len = ieee_addr_to_str(ieee_addr_buf, sizeof(ieee_addr_buf), extended_pan_id);
if (addr_len < 0)
{
strcpy(ieee_addr_buf, "unknown");
}

NRF_LOG_INFO("Joined network successfully (Extended PAN ID: %s, PAN ID: 0x%04hx)", NRF_LOG_PUSH(ieee_addr_buf), ZB_PIBCACHE_PAN_ID());

zb_zdo_pim_set_long_poll_interval(ZB_MILLISECONDS_TO_BEACON_INTERVAL(10000));
// zb_zdo_pim_set_long_poll_interval(ZB_PIM_DEFAULT_LONG_POLL_INTERVAL);
// zb_zdo_pim_start_turbo_poll_packets(10);
}
else
{
NRF_LOG_ERROR("Failed to join network (status: %d)", status);
bsp_board_led_off(ZIGBEE_NETWORK_STATE_LED);
zb_err_code = ZB_SCHEDULE_APP_ALARM(door_lock_leave_and_join, 0, ZB_TIME_ONE_SECOND);
ZB_ERROR_CHECK(zb_err_code);
}
break;

```
