nrf52832 ble FCC Testing Failed

[Home]

Hi Team,

I am doing FCC testing for NRF52832 BLE. As part of firmware code initialization i  have following functions 

nrf_sdh_enable_request(),

nrf_sdh_ble_enable(),

ble_advertising_init(),

ble_advertising_conn_cfg_tag_set()

ble_advertising_start()

sd_power_dcdc_mode_set()

I am using radio tool radio_modulated_tx_carrier_duty_cycle() function to generate radio waves for FCC testing.

If iam enabling the init functions i am not getting any waves on Spectrum analyzer. I am able to observe the waves only when i disable the init functions.

Do we need to disable the initialization to perform FCC testing using radio tool??

If so, Can any one please explain me why we need to disable init functions??

Hi,

 

You are not able to access the RADIO registers when the Softdevice is enabled. Regulatory (e.g. FCC) testing is anyway usually performed with a device that only runs a test application, such as our radio test example or DTM example, not the end application.

 

Best regards,
