Unable to use the DTM example for nRF5340 DK (PCA10095)

[ShuMan]

I am trying to use the DTM example for nRF5340 DK (PCA10095). The example is located at "C:\v1.7.0\nrf\samples\bluetooth\direct_test_mode", but I am facing "NRF_RADIO_Type" error along with few more errors with 1.7.0 as well as 1.9.0 SDK. I have attached the error log files' links below.

SDK 1.7.0 error log: https://drive.google.com/file/d/1m75QjX6ug_ym6KEYMkzjd8zMPitysDJz/view?usp=sharing

SDK 1.9.0 error log: https://drive.google.com/file/d/1epy6gnY7Dz73dMOb64afPjl9ZBsMckIp/view?usp=sharing

I have also tried using SDK 1.9.1, however I am unable to open the DTM project in it.

Thanks.

Hi,

I have tried it once again but no luck. Attaching the dtm_init() function code where I have added the lines.

Thanks

int dtm_init(void)
{
	int err;
	
	NRF_VREQCTRL->VREGRADIO.VREQH = 1;
	while(NRF_VREQCTRL->VREGRADIO.VREQHREADY == 0);

	err = clock_init();
	if (err) {
		return err;
	}

	err = timer_init();
	if (err) {
		return err;
	}

	err = wait_timer_init();
	if (err) {
		return err;
	}

#ifdef NRF52840_XXAA
	/* Enable the timer used by nRF52840 anomaly 172 if running on an
	 * affected device.
	 */
	err = anomaly_timer_init();
	if (err) {
		return err;
	}
#endif

	err = gppi_init();
	if (err) {
		return err;
	}

	/** Connect radio interrupts. */
	IRQ_CONNECT(RADIO_IRQn, CONFIG_DTM_RADIO_IRQ_PRIORITY, radio_handler,
		    NULL, 0);
	irq_enable(RADIO_IRQn);

	err = radio_init();
	if (err) {
		return err;
	}

	dtm_inst.state = STATE_IDLE;
	dtm_inst.new_event = false;
	dtm_inst.packet_len = 0;

	return 0;
}

Hi,

When you set the value of radio output power to 0 dBm, it will be increased by 3 dBm. For setting the radio output power, you can use nrf_radio_txpower_set function from nrfx radio driver.

Best regards,
