Hi,
I am start to look into getting FCC compliance testing for my nRF52 product.
I am using PCA100040 nRF52-DK for radio test and facing irregular wave duty cycle problem. Duty cycle is change continuously.
SDK: 11.00.00
Stack: ANT_s212_nrf52_0.9.1.alpha.hex
More info see attached waveform image.
Can anyone known how resolve this issue?
My Firmware:
/**@brief Function for application main entry. Does not return.
*/
int main(void)
{
uint32_t err_code;
nrf_clock_lf_cfg_t clock_lf_cfg = NRF_CLOCK_LFCLKSRC;
// Setup LEDs
LEDS_CONFIGURE(LEDS_MASK);
// Setup SoftDevice and events handler
err_code = softdevice_ant_evt_handler_set(ant_scaleable_event_handler);
APP_ERROR_CHECK(err_code);
err_code = softdevice_handler_init(&clock;_lf_cfg, NULL, 0, NULL);
APP_ERROR_CHECK(err_code);
err_code = ant_stack_static_config();
APP_ERROR_CHECK(err_code);
// Setup and open channels
//ant_scaleable_channel_tx_broadcast_setup();
sd_ant_cw_test_mode (10,RADIO_TX_POWER_LVL_CUSTOM,RADIO_TXPOWER_TXPOWER_Pos4dBm,1);
// Enter main loop
for (;;)
{
err_code = sd_app_evt_wait();
APP_ERROR_CHECK(err_code);
}
}
Regards,
Himansu
