How to completely turn off the radio (power consumption test)

[Leo Mo]

SDK: nRF Connect SDK v2.9.0

Chipset: nRF52840

I'm using ncsv2.9.0nrfsamplesperipheralradio_test to test the RF.

The initialization code is as follows:

            struct radio_test_config test_config;
            memset(&test_config, 0, sizeof(test_config));
            test_config.type = UNMODULATED_TX;
            test_config.mode = NRF_RADIO_MODE_BLE_1MBIT;
            test_config.params.unmodulated_tx.txpower = RADIO_TXPOWER_TXPOWER_Pos8dBm;
            test_config.params.unmodulated_tx.channel = 2;
            radio_test_init(&test_config);
            radio_test_start(&test_config);

At this time, the measured current is approximately 15.35mA.

Cancel code:

radio_test_cancel();

After canceling the RF output, the measured current is about 15.3mA, which indicates that the radio does not seem to be turned off.

How can I completely turn off the radio?

Hi Leo

I will look into your case. Just from the looks of it, it seems like you have modified the sample. Is this correct? Normally you would configure the application over CLI, are you doing it?

In my application, there is no CLI.

Hi runsiv 

I have fully ported the radio_test code now, but even after turning off the radio, there is still a current of 480+uA.
