Comprehensive DTM guide

[Jamie]

Hi,

I am using the nRF6310 + PCA10005 +nRFgo Studio as the lower tester, the supplied python scripts as the upper tester, and my own custom board as the DUT.

I've looked through all the separate documentation I can find, e.g. nAN-34, Dev Kit user guide, nRF6700 user guide, nRFgo Studio help (F1 menu), etc., and all seem to provide a very high level description of what DTM mode does and what the system-level setup looks like.

What I'm looking for is more of a step-by-step tutorial for how to execute the DTM test. Is there any other resources missing from my list that could help me, or what other suggestions could you provide to help me get my first test running for my custom hardware?

Thanks, Jamie

We don't really have any other resources than the ones you list, but I would expect them to cover what's needed. If you have specific questions, I'd recommend you to post them separately, so that we can try answering them one-by-one.

In general, the steps would be to make sure you connect a UART interface on your PC to the UART lines configured in ble_app_dtm (change them if you want), and then start the DTM test. Depending on whant you want, you can use a spectrum analyzer, connected to the antenna output of the radio chip to measure everything that's needed. Just for initial testing, you should also be able to just connect an antenna and see for instance a carrier. If you want to use a full transmit/receive test, you'd have to have another DTM application connected to a different UART port to be used as the receiver (or transmitter).
