Hello,

I am really sorry that it was a private case link. The case is about TX power control of zigbee.

ZBOSS stack configures the radio TX power and by default it attempts to set maximum possible gain. You can use Production Config to change the default TX power set by ZBOSS.

You can see some more info about it here: https://infocenter.nordicsemi.com/index.jsp?topic=%2Fsdk_tz_v4.1.0%2Fzigbee_prog_principles.html&anchor=zigbee_production_config

To use production config, you need to:

generate hex file that contain the ZBOSS Production Config using nrfutil:
- some documentation: https://infocenter.nordicsemi.com/index.jsp?topic=%2Fug_nrfutil%2FUG%2Fnrfutil%2Fnrfutil_prod_config_generate_hexfiles.html
- in the input yaml file put only the fields you actually want to change (like tx power, channel mask), remove the unused ones (example yaml file is printed as help message nrfutil zigbee production_config --help)
- set correct offset using --offset, use start address of zboss_product_config partition (list of partitions and addresses are in partitions.yml in the sample build folder).
flash the hex file along with the firmware

Hello,

I have feedback from our zigbee expert.

nrf_802154_tx_power_set() needs to be set after the stack has started or the ZBOSS stack will override it. you can set use production config to set it, according to this case https://devzone.nordicsemi.com/support-private/support/290822.

You can look at the following documentation to know about production configuration https://developer.nordicsemi.com/nRF_Connect_SDK/doc/zboss/3.11.3.0/zigbee_prog_principles.html#zigbee_production_config of Zigbee.

Hello,

Sorry for the delay.

Yes, I set the Tx Power before the zboss stack start.

After using nrf_802154_tx_power_set(int8_t power) get the correct value, but when ZBOSS Stack start return to 0.

Hello,

Have you tried to set the TX power value before the zboss stack start?

After changing TX Power call what is the result you get as output? What is the return of nrf_802154_tx_power_get() function?
