RE: BLE packet loss testing

I assume you refer to receiver blocking test in RED, 300 328, where you should be testing packet loss on fixed channel.

So, based on that you may consider to use Direct Test Mode (DTM) for RED, 300 328 for your test. You should then have UART exposed, and you can use nAN34 as reference on how to setup this test:

I did make a modification to the above example in this thread, this will make it easier to only run receiver or transmitter for test:

The DTM for the nRF52 is part of the nRF5 SDK:

Fyi or others finding this thread:

There is also a blocking test that is part of EMC, 301 489, where it is the functionality of the end product that is tested during test (with the protocol running). The intention is to test the final product and verify that the product can operate as intended, for this test it's up to the manufacturer what is the pass criteria, e.g. it can be that if you are making a keyboard that your button presses are displayed on the screen, then the test is passed.
