I got the all details from this article that was useful among the all aspect having federation on this that was useful. You can get the all assignment from https://edubirdie.org/edubirdie-review-the-most-honest-and-reliable/ this has the all famous writers on this that was good. I also got the CW test details from this that was good to have the all frictions on this.

Hi,

Please see the updated code above, turns out that the test mode init was missing.

Thanks , the sd_ant_cw_test_mode() code works for me (In modulated mode only ). I will stay tuned for new S212 releases fixing the 'unmodulated mode' issue .

Hi,

Try the following code:

/**@brief Function for application main entry. Does not return.
 */ 
int main(void)
{
    uint32_t err_code;    
    
    // Setup SoftDevice and events handler
    err_code = softdevice_ant_evt_handler_set(ant_evt_dispatch);
    APP_ERROR_CHECK(err_code);

    err_code = softdevice_handler_init(NRF_CLOCK_LFCLKSRC, NULL, 0, NULL);
    APP_ERROR_CHECK(err_code);
    
    err_code = ant_stack_static_config();
    APP_ERROR_CHECK(err_code);

    sd_ant_cw_test_mode_init();
    // sd_ant_cw_test_mode assumes that the hfclck is enabled.
    // request and allow 2 ms to stabilize
    sd_clock_hfclk_request();
    nrf_delay_ms(2);

    APP_ERROR_CHECK(sd_ant_cw_test_mode(33,RADIO_TX_POWER_LVL_CUSTOM,RADIO_TXPOWER_TXPOWER_0dBm,1));
    for (;;)
    {
        uint32_t err_code = sd_app_evt_wait();
        APP_ERROR_CHECK(err_code);
    }

}

The code gives a 0dBm output on channel 33. This code works fine for both modulated and CW for s210 and s212.

If this doesn't work for you, leave a comment below. As a workaround you can use the radio test example. This example can be found in [YOUR_SDK_LOCATION]\nRF5_SDK_11.0.0_89a8197\examples\peripheral\radio_test\pca10028\arm5_no_packs in our most recent SDK 11.

Best regards,

Øyvind
