How to change the Thread COAP examples to work with the NRF 52840 Dongle

[David Jones]

Hi, I am wanting to try out the COAP examples in the thread and zigbee 2.0 SDK on the NRF52840 Dongle. However, I am failing to to get it working. The original makefile would create a hex file that refused to be flashed to the dongle via the programmer app. I then thought to change the linker script of the makefile to /openthread_nrf82840_boodloader.ld. This fixed the issue of the hex file not being able to get flashed to the dongle but then the dongle would become unrecognisable to the PC.

What do I need to change so that the Thread COAP examples will work with the NRF52840 dongle?

Thanks.

The application can be built for DK board, but not for dongle. and I've gone through the whole code. The hardware mentioning (GPIO pins, Buttons, LEDs) and libraries and all are of DK boards, so

as you can see in the image, this application was not made for dongle,

but if I select Nordic boards, somehow it will build the application, but I've checked. It wont work

1. How can I make CoAP work on nrf52840 Dongle?

2. How is the code different from DK boards?

3. In future If I want to make any application from scratch, but when there is no base template, how can I work on it?

gautamvhavle , please create a new thread for this. You are using the nRF Connect SDK, while OP was asking how to do this with the nRF5 SDK for Thread and Zigbee SDK.
