nRF5340 automatically runs DTM when power is supplied

[Hannibalhz]

Dear Nordic

I have a question to ask your.When I used the NRF52 Series and nRF5 SDK,I made a simple modification tot the radio test program in examples\peripheral\radio_test so that the NRF52 series chip can be directly fixed at the frequency when the program is running.I don't need the uart to control it.

I would like to know where how modify the radio test program in NCS SDK to achieve the same effect for nRF5340.I studied the radio_test program of NCS SDK,an it's structure seems to be different from the radio test program in nRF5 SDK.Plese help me.

Thank you for your supprot and best regard.

Hi,

 

In main.c, you add these headers:

#include "radio_test.h"
#include <string.h>

And this code:

	struct radio_test_config my_config;
	memset(&my_config, 0, sizeof(struct radio_test_config));
	my_config.type = UNMODULATED_TX;
	my_config.mode = NRF_RADIO_MODE_BLE_1MBIT;
	my_config.params.unmodulated_tx.txpower = RADIO_TXPOWER_TXPOWER_0dBm;
	my_config.params.unmodulated_tx.channel = 40;

	radio_test_start(&my_config);

 

And you should have a unmodulated carrier at channel 40.

 

Kind regards,

Håkon
