Alan Ajit

Dear nordic,

1. Is it possible to create thread networking using dongle?

2. I want to create Thread CLI example in dongle but the problem here is UART pins and LEDS. what changes needed to work properly in dongle?

3. how i change nrflog uart to another pin(is that make any problem)?

4. Is it any application note for thread that its working( program work flow) ?

    Hi Alan, 

    Andrew answered most of your questions. I just want to give some additional information. Since our Thread SDK using OpenThread stack and the OpenThread stack is build on platform specific ( in this case PCA10056), if you want to use the stack for the dongle PCA10059 you would need to recompile the OpenThread stack. 

    In particular you would need to modify the platform-config.h here, and recompile the openthread stack. 

    In addition, on the dongle there is no UART-USB chip but the USBD integrated on the dongle. This requires some code change to use the USB peripheral on the chip. It may not straight forward, the workaround is to use another pin on the dongle and connect it to an external UART-USB chip/cable. 

    As suggested by Andrew, it's better to start your development on a nRF52840 DK instead. When you need to test / demo on multiple nodes, you can use the dongle, but having UART/CLI on the dongle would need some extra work.

    Thanks for your replay. i think the nrf log uart use pin 6 and 8 as default is it right?

    i want to change this pin for dongle till now i didn't get where i change this pin( i searched platform-config.h but not find). i need your help to change that pin. is it possible to change nrf log uart pin?

    I tried to change log uart pin and send thread cli commands through that but now the default log pins are 8 and 6 but  in dongle that are not in use so i want to change that. can you help me where i change this pin?
