Certification for nRF52840

[Gianlucamilani]

Good morning,

I need to perform precompliance tests for my board based on the nRF52840.

I read in this ticket: 

https://devzone.nordicsemi.com/f/nordic-q-a/59242/certification-procedure-for-a-nrf52832-based-module

that for the radio tests you suggest to use the "radio test example" firmware in the nRF5 SDK. 

However, in my case the requirements are the following:

- I do not need to switch the frequency between channels (I have to stay fixed at one)

- I need to send always at maximum power (I do not need to switch)

- the communication has to be constant (continuous transmission, not pulsed)

- my device cannot receive serial data from the PC

Could you tell me:

- if I can still use the "radio test example" or if you suggest to use something else

- in the first case, which are the configuration parameter that I have to set inside the firmware to obtain my requirements?

Another point: in case I would like to change also the frequency, which is the related parameter?

Thanks in advance,

Best regards,

Gianluca Milani

Hi, 

yes you can still use the radio test example and the DTM example

Best regards,

Thank you very much for your answer,

could you tell me the variables to be modified in the 'radio test example ' firmware to set:

- a fixed frequency (and understand which I am selecting)

- the maximum power

P.S.: is the transmission constant (not pulsed)?

Thanks,

Gianluca

For the Direct Test Mode (DTM), we rely on the Bluetooth core specification that describe the commands and events for DTM.

For the the radio test mode, we provide example, documentation, header and source code, that should make it possible for you to find out how you can use this api.

You will need to use this along with the register descriptions:
https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/radio.html#register.FREQUENCY

https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/radio.html#register.TXPOWER

In general for modulated packets it will "pulsed" for unmodulated carrier it will be "continues".
