High Power Consumption on nRF52840-DK using zboss_start_no_autostart()

[Ignacio]

Using zboss_start_no_autostart() instead of zboss_start() will cause a power consumption of 630uA. I was expecting the device to be sleep and in a very low power mode.. All the changes are implemented over the nRF5 SDK for Thread and Zigbee v3.2.0 using the light switch zigbee example. The current measurements are done using a high precision mutlimeter connected to the nRF Current Measurement connector P22.  I was expecting the current to be around this figure:

Not all Zigbee examples are optimized for power consumption. To get the best low power performance you need to look at Zigbee Sleepy End Device example. When you enable the mode, as documented, you'll get ~4uA in sleep.
