nrf connect sdk : nrf52833 take DTM

[hamarsa]

Hi nordic team,

i want to use DTM for nrf52833 in Nrf Connct Sdk.

however,in document:

do it mean that only nrf5340 and nrf52840 can take DTM in NCS?

can i use DTM for nrf52833 by copying code from sample project?

Thanks

Hi,

 

You can use DTM with all nRF5-series devices.

For nRF52833, you can create an overlay file in the boards/nrf52833dk_nrf52833.overlay:

/ {
	chosen {
		ncs,dtm-uart = &uart0;
	};
};

&uart0 {
	status = "okay";
	current-speed = <19200>;
};

&radio {
	status = "okay";
	/* This is a number of antennas that are available on antenna matrix
	 * designed by Nordic. For more information see README.rst.
	 */
	dfe-antenna-num = <12>;
	/* This is a setting that enables antenna 12 (in antenna matrix designed
	 * by Nordic) for PDU. For more information see README.rst.
	 */
	dfe-pdu-antenna = <0x0>;

	/* These are GPIO pin numbers that are provided to
	 * Radio peripheral. The pins will be acquired by Radio to
	 * drive antenna switching.
	 * Pin numbers are selected to drive switches on antenna matrix
	 * desinged by Nordic. For more information see README.rst.
	 */
	dfegpio0-gpios = <&gpio0 4 0>;
	dfegpio1-gpios = <&gpio0 5 0>;
	dfegpio2-gpios = <&gpio0 6 0>;
	dfegpio3-gpios = <&gpio0 7 0>;
};

 

For other devices, such as nRF52832/810, you can rely in the already present "app.overlay" file.

 

Kind regards,

Håkon
