Questions about Indonesian certification sop?

You will usually need to setup a modulated carrier at 2402, 2440 and 2480 MHz. DTM is suitable if you can use a Bluetooth tester or send the commands from fa GUI, for instance teh DTM plugin in nRF Connect for desktop.

You can also take a look at the radio test example in the SDK: https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.1.0/nrf_radio_test_example.html

Ok thank you for your reply, I can write a step to the tester according to how to enter the DTM.
