Direct test mode on nRF52840

[Sridhar Jonnavittula]

Hi all,

I want to use the python scripts provided in application notes in nordic documentation to run DTM example flashed into nRF52840 SoC. So when I open command prompt-->goto python example script location-->give python example.py command it is giving prints what ever I keep but tranmitter/receiver/both tests are not executing and script returns with

this error. If I get rid of this error think I can proceed with this. Is there any issue with DTM library, windows tools etc?

Thanks,

Sridhar

The actual serial port (COM) ports depend on Windows, so you need to edit example.py and modify:

setup['TestSerialPortName'] = "COMxx" #DUT (Device Under Test)
setup['GoldenSerialPortName'] = "COMxx" #Golden sample (Tester)

Kenneth,

We have to do production testing of our product. For mass production testing to do faster, can you specify me which of production programming among PEmicro, segger production programmers, nrfjprog can I use for mass production of modules.

Thanks,

In the getting started sections you may find some guidelines: http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.gs/dita/gs/gs.html?cp=1 

Personally I only use nrfjprog in my daily work, so I don't have any specific preference.
