The main problem was making the dongle work. + +After accidentally removing the bootloader in the dongle, it wasn't working properly. To solve this, a bootloader hex file is needed to erase and write in the dongle with a segger j-link and the nrf connect for desktop programmer. The bootloader will be referenced in GitHub. + +To make example nrf/samples/bluetooth/mesh/light or switch work with the dongle a change is needed in the .conf file. + +After removing these two lines from the .conf file it will work exactly as you’d expect. For the development kit, it doesn't need to change. + +Lastly to make debugging work with the RTT viewer there needs to be configurations added to the .conf file(see below). + -WIP # Manual nRF toolchain installation @@ -178,3 +191,4 @@ These are the links used for Bluetooth mesh research 10.
