Getting started

[AndreasE]

Hello there,

We are a test lab based in Leatherhead UK, and would like to use your nRF52840-DK for setting up a test jig to communicate with a DUT(Device Under Test)

to carry out EN 300 328 measurements. The following assistance steps are required:

i) How to power up the device

ii) How to address the device to get some traffic going between the DUT and the nRF52840

iii) How to start/stop the traffic

iv) How to control the put-thought of the traffic

vii) How to select a particular BT channel for the traffic

Regards

Andreas

Hello,

The closest that can fit your requirements I believe are DTM:
https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/ble_sdk_app_dtm_serial.html?cp=5_1_4_5 

You will need to provide serial UART commands as specified in the Bluetooth core specifications to the nRF52840 to setup the mode you want to measure.

If you intend to run this on a nRF52840-DK (PCA10056) you should find precompiled hex files you can program in \examples\dtm\direct_test_mode\hex folder when download and unzip SDKv15.3

To program the hex file you can download nRF Command line tools, and for instance run 'nrfjprog --eraseall' and 'nrfjprog --program direct_test_mode_pca10056.hex' from command prompt.

You may also find this useful, since it show how to for instance interface DTM in production (however you want to do the same, even though in a less scale):
