Modulation by radio_test_example

[UBAN]

I use radio test example in SDK 12.2.0.

Is it possible to perform modulation with PRBS9?

Do you want PRBS9 packet payload for DTM testing? If so, you can use the DTM example in the SDK together with the python script that comes with the application nAN-34, and set the bit pattern to PRBS9 in the python script.

Thank you very much.

I use the Radio Test Example in the following link.

infocenter.nordicsemi.com/.../nrf_radio_test_example.html

When a modulation starts with the "o" command, is the bit pattern PRBS 9?

The modulation in the radio_test example is just a 254 byte random payload, see generate_modulated_rf_packet().

The content of a PRBS9 packet payload can be found in the DTM example --> ble_dtm.c --> PRBS9_CONTENT. If you want your packet in the radio_test example to have that content, you can copy it into the radio_test example.

Thank you for the reply.

I found PRBS9_CONTENT, but I did not know how to insert it into the radio_test example.

If you do not mind, could you get the radio_test example corresponding to PRBS9?

How did you try to add the PRBS9 content to the packet in the radio_test example? And what didn't work?
