Adapting light switch example to nrf52840 dongle.

[PaulvB]

Hello,

I have been trying to get the light switch server from the Mesh SDK examples running on a nrf52840 dongle.

The dongle does not show in the Mesh app when scanning for nodes.
All the onboard LEDs turn on, which from what I could find online means that an error has happened somewhere.

I have tested the server on a DK where it seems to run fine. I can connect to it from the Mesh app.
I have verified the dongle by running the blinky and ble_app_blinky example projects, These seem to work fine.

I have used the following links to guide me through the process:
https://devzone.nordicsemi.com/nordic/short-range-guides/b/getting-started/posts/nrf52840-dongle-programming-tutorial
https://devzone.nordicsemi.com/f/nordic-q-a/46656/problem-in-setting-nrf-52840-dongle-as-proxy-server-for-light-switch-example

So in short:
1) Changed the preprocessor definition to BOARD_PCA10059.
2) Added the code from Bjorn to simple_hal.c.
3) Build the project in segger.
4) Programmed the dongle with the resulting hex + a softdevice.

I am using:
Mesh SDK 3.2.0
nRF5 SDK 15.3.0
nRF Connect 3.3.0
nRF Mesh app 2.1.0

I have tried the following softdevices:
s140 6.0.0
s140 6.1.0
s140 6.1.1

Please do let me know if I need to provide any extra information.

Hi,

Following everything from the nRF52840 Dongle Tutorial should generally lead to a working application, so it is hard to tell what may be missing.

The best way to figure out what happens is to connect the Dongle to a programmer, either using a 10 pin Tag Connect cable or soldering wires directly on the Dongle. Not having a debugger connected severely limits the debugging capabilities. From your description it sounds like you get an assert and end up in the fault handler. From a debug session you should easily get file and line number.

By the way, have you tested the project that Bjørn provided in that other DevZone thread, on the Dongle?
