Zigbee + FreeRTOS End Device power consumption

[sjf]

Hi,

We have been working with an end device based on nRF52840 with nRF5_SDK_for_Thread_and_Zigbee_v4.0.0_dc7186b

By measuring with the power profiler kit, we got a system's power consumption of about 50uA. But after we call zboss_start_no_autostart() and zboss_main_loop_iteration() periodically (we tried from 50ms to 1s) we realized that the current consumption varies from 500uA to 1mA. This is how the Zed is configured:

  zb_set_ed_timeout(ED_AGING_TIMEOUT_64MIN);
  zb_set_keepalive_timeout(ZB_MILLISECONDS_TO_BEACON_INTERVAL(3000));
  zb_set_rx_on_when_idle(ZB_FALSE);

Since we're using FreeRTOS and SoftDeivce, we can't call zb_sleep_now(). Is there any way to turn off radio during inactivity times or any other
considerations?
Also, is there any improvements on this topic betweennRF5_SDK_for_Thread_and_Zigbee_v4.0.0 andnRF5_SDK_for_Thread_and_Zigbee_v4.1.0?

Thanks in advance.
Regards,

Santiago

Hello,

Can you please see my colleague, Susheel's, reply in this ticket:
https://devzone.nordicsemi.com/f/nordic-q-a/35073/high-power-consumption-of-softdevice

I see that this is at least not "patched" in the 4.0.0 Thread and Zigbee SDK.

Best regards,

Edvin

Hi Edvin,

Thanks for your response. But the increase on current consumption was ONLY after zigbee was initialized and  when calling zboss_main_loop_iteration() function in the zigbee task,

Prior to that, the calling to sd_app_evt_wait() was not generating any issue like your link mentions
