Programming the nRF51822 module with DTM
The nRF51822 module has to be programmed with the DTM application found in the nRF51 SDK. This
application is provided with its source code and needs to be compiled using Keil.
1. Locate the DTM application project found under <Keil path>
\ARM\Device\Nordic\nrf51822\Board\nrf6310\direct_test_mode\arm
.
2. Open the DTM project in Keil μVision by double clicking the
direct_test_mode.uvproj
file.
3. Click the
Build
icon or press
F7
to build the project.
4. Only one SEGGER device should be connected to your computer. Make sure it is also connected to
the nRF51822 development module to ensure the program is downloaded to the correct target.
5. Go to the
Flash
menu and click
Download
to load the program (or click the
Load
icon).
You are now ready to start DTM testing either using the Direct Test Mode UART interface included in nRFgo
Studio or connecting 3rd party equipment.
