How to port the Zigbee Network Coordinator sample from the nRF52840DK to the nRF52840 dongle

Question

I'm trying to implement the Zigbee coordinator sample on the nRF52840 dongle. Although I've received a little bit of guidance on how to adapt the nRF52840DK implementation from my local Nordic rep, neither he nor I are enjoying any success. Surely there must be others that have done this before, no? Once I get this sample working, I would like to add the CLI shell to the same sample. Can anyone provide some desperately-needed assistance? I am building my code using nRF Connect SDK v1.8.0 in VS Code on a Windows 10 machine and have successfully built and tested the very same sample on the DK board without issue.

Hi, 
 To get the network coordinator to work on the Dongle you need to do the following: 
 1. Create a board file overlay nrf52840dongle_nrf52840.overlay under network_coordinator/boards with the following: 
 /*

 */

/ {
	chosen {
 zephyr,entropy = &rng;
	};

	buttons {
 compatible = "gpio-keys";
 rst_button0: rst_button_0 {
 gpios = <&gpio0 19 (GPIO_PULL_UP | GPIO_ACTIVE_LOW)>;
 label = "Reset button";
 };
	};

	aliases {
 rst0 = &rst_button0;
	};
};
 
 2. Create a static partition manager file to create partitions for MBR and the bootloader on the Dongle. This should be located directly under network_coordinator/. Call it pm_static_nrf52840dongle_nrf52840.yml and add the following: 
 EMPTY_0:
 address: 0x0e0000
 end_address: 0x100000
 region: flash_primary
 size: 0x20000
# SRAM reserved to be used by the nRF5 Bootloader
EMPTY_1:
 address: 0x20000000
 end_address: 0x20000400
 region: sram_primary
 size: 0x0400
 
 3. The last thing is to add the dongle to the existing sample.yaml file. Simply add nrf52840dongle_nrf52840 to platform_allow and integration_platforms. 
 I have also uploaded the sample with dongle support here. 
 I would like to add the CLI shell to the same sample 
 By this, do you mean the Zigbee shell library or CLI in general? The issue with using the Zigbee shell with the Dongle is that as of now it is only supports using UART and RTT as serial transports, as can be seen in Zigbee shell » Supported backends , and the Dongle only has USB, so you would need to use USB CDC ACM. It might be possible to implement this, but I have not tested it myself. If you want to look into it, you can take a look at the USB overlay extension in the Thread: CLI sample, and the USB CDC ACM Sample Application . 
 Best regards,
