Commands for channel selection and continuous transmission

[jesortsan78]

Hello,

We have developped a product with the nRF52832. Basically, it is a power sensor that uses both BLE (advertising) and ANT+ to send data regularly to a display (third party device).

Is it any way to select the channel used by BLE to advertise? Certification laboratory is asking me about that. I have try to find some info but I haven't, so I'm not sure that such a thing can be done.

On the other hand, they're also asking about continuous transmission? They need that operation mode for testing purposes. Is there any way (command) to do that? Is there any example program that operates in that mode?

I appreciate any help on this matter, since I am a bit lost.

Regards
Jesus

The BLE (softdevice) stack doesn't have any commands for this. You must use either Direct Test Mode, DTM, or the radio test example for this. DTM can't do continuous transmission so you should use the radio test here.

nRF5:

DTM https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/bluetooth/direct_test_mode/README.html

You can control the radio test with a CLI terminal over UART

Hi Ketil,

Thanks for your reply. It helps a lot. I will take a look into the info.
