Time out error while production test using DTM

[Cimteker]

Hello,

I am testing 9 channels for PER (1,2,3,21,22,23,37,38,39). During testing the last 3 channels I always get a single time out error in response to LE_TEST_END. I also get much higher PER for higher channels (not sure if these 2 problems are related). Anybody with a similar experience? I am using nRF51 dev kit.

Thanks

Jerry

Sounds like there's something hanging on either the DUT or the tester-side, that requires a delay between tests. I am sorry, but I cannot say anything more in detail here, as there are components here that are out of scope to the products that we deliver. The python scripts delivered with nAN-034 are developed by us, but once you build a GUI on top, it becomes a lot more complex in terms of whats happening in the chain of communication. I'm not stating that the python scripts are waterproof in all scenarios, but I'm just pointing out the complexity compared to running a 10 line python script for one test.

Has the setup behaved like this before with other devices? If your setup has not been behaving this way with other production runs prior to this, it may point to the firmware running on the DUT misbehaving.

 

Kind regards,

Håkon
