Hi Edvin, it was my mistake. I was calling nrf_802154_tx_power_get in a bad way.

Both.

My example does not use SoftDevice. What about yours?

I just tested this, but I don't get the same behavior as you. I tested both examples with and without the softdevice.

Try to add the following snippet, and monitor the log:

    int8_t power = nrf_802154_tx_power_get();
    NRF_LOG_INFO("power: %d", power);
    power = 8;
    nrf_802154_tx_power_set(power);
    int8_t power2 = nrf_802154_tx_power_get();
    NRF_LOG_INFO("power2: %d", power2);

e.g. right before the while loop in main().

If it didn't work, how did you call nrf_802154_tx_power_get()

By the way, the value retrieved by nrf_802154_tx_power_get() is always 8 even when nrf_802154_tx_power_set() is called with another parameter.

Hi,

I'm calling nrf_802154_tx_power_set() with 0, 8 and -8 before and after starting the stack on the coordinator and on the end device.

When calling the function zb_zdo_get_diag_data() on both sides, It always return the same range of values (-60 aprox) no matter the tx power setting....

Hello,

If you want to change the output power with the zigbee stack, you should use that function, nrf_802154_tx_power_set(). This function is implemented in the 802.15.4 library that the zboss stack uses, located in external/zboss/lib/keil/nrf52833/nrf_radio_driver.lib (or equivalent, depending on what IDE you are using.

How do you determine that nothing happens?

Best regards,

Edvin
