nrf52840 zigbee tx power value in radio test ????

[Dev_Dev]

I recived nrf5 SDK V17.0.2

I'm testing  with in "nRF5_SDK_17.0.2_d674dde\examples\peripheral\radio_test" folder.

I tried zigbee tx carrier mode start at 11 channel and tx power = NRF_RADIO_TXPOWER_POS8DBM. 

But, When measured with measuring equipment, i got zb tx power -20 ~ -30 value.

this tx power value is expected to be zigbee tx is not carrier...??..

Please tell me the wrong  or Please let me know what I need to add.

 

See below main routine.

int main(void)
{

uint32_t err_code;

log_init();

err_code = nrf_drv_clock_init();
APP_ERROR_CHECK(err_code);
nrf_drv_clock_lfclk_request(NULL);

err_code = app_timer_init();
APP_ERROR_CHECK(err_code);

clock_init();
radio_cmd_init();

cli_init();
cli_start();

NVIC_EnableIRQ(TIMER0_IRQn);
__enable_irq();

zb_tx_modulated_carrier_start(11);

 while (true)
 {
   UNUSED_RETURN_VALUE(NRF_LOG_PROCESS());
   nrf_cli_process(&m_cli_uart);
 }
}

Hi,

The radio power example allows you to test the radio peripheral directly, without using any protocol. You have to use the CLI command 'output_power' in order to set the output power in the example.
