Is there example for continuous broadcasting of the carrier in the nRF5_SDK_15.2.0_9412b96

[BartoszT]

I need to tune the matching circuit for antena and I need pure radio carrier signal,

How to get this?

You'll need to use the Direct Test Mode functionality for the BLE.

There are examples, but they mainly revolve around using external hardware to drive the DTM functions over UART (which will be needed for certification), but it is possible to do this with direct code yourself.

I can't remember the exact code, but I'll have a look.

Edit: I think that you'll need something like

dtm_init();
dtm_cmd(CARRIER_TEST, 19, 0,0);// start carrier with no modulation channel 19
.
.
.
dtm_cmd(LE_TEST_END,0,0,0);

Hi, 

you can use the Radio test example in the SDK;
'start_tx_modulated_carrier' modulated, 'start_tx_carrier' not modulated.
