otSysInit causes nRF52840 dongle to freeze

[Siggy]

I am currently trying to implement a Thread functionality on an nRF Dongle connected to a windows machine. Its intent is to be able to recieve messages from other thread components, and transfere the messages to a windows application. 

I have tried following different examples, such as the MQTT_client_publisher and Coap_server, but I keep getting stuck on an issue where the dongle freezes when calling otSysInit(0, NULL);. Is this call needed to use thread?

I have also tried to include softdevice, (s140.6.1.0) when flashing the application, but it does not fix the issue. 

Any help is greeted with thanks! 

Best Regards

Hi,

There is not so much to go on here yet. Which Thread & Zigbee SDK  version are you using? How have you ported the application to run on the dongle? Do you have any means of debugging on the dongle? If not, I suggest you either develop on a nRF52840 DK first, so that only small modifications are needed to migrate to the dongle. If you do, it would be interesting to dig deeper and see at which state the system is in when you write it freezes (which you could check using a debugger).
