DTM sample project

[Tak]

I would like to measure BER and PER on custom board by using sample project that is included SDK.

\examples\dtm\direct_test_mode\pca10028\s110

Could you please teach me about below questions?

1. The value of the PER and BER is measured in the sample project of the above?
2. If NO, I should use external equipment such as MT8852 for RF evaluation?
3. If YES, please teach me about mechanism of BER measurement.

Best Regards,

I suggest that you take a look at the nAN34 - Setting up production test using DTM application note, which can be found on this page on our Infocenter.

You can use a nRF51/52 DK or a Bluetooth Tester(e.g. MT8852) to perform the test. If you use the nRF51/52 as the Upper Tester as described in the application note, then you can also take a look at the attached pdf, it explains briefly how to setup the python scripts and show the output of the script with different attenuation levels.
