nRF52 Unintentional Radiator Test Device Mode

[Zhi Xuen Lai]

We are preparing our nRF52 product for the unintentional radiator test. Currently, the SoftDevice is enabled and we have the low power mode disabled with the following changes: 

// From this
result = sd_power_mode_set(NRF_POWER_MODE_LOWPWR);

// to this
result = sd_power_mode_set(NRF_POWER_MODE_CONSTLAT);

The test plan calls out the following requirement:

“All wireless radios (if applicable) will be placed in a continuous receive mode or in an idle state (radio powered, not transmitting) during unintentional emissions testing.”

Is there anything else we need to modify the state of the SD?

You can't really use the SD for this as you don't have full control over the radio with it. Much better to use the "Radio test example" in the SDK and set the radio in continuous receive mode.
