I have build many applications using the NRF5 SDK. I have a custom service that works fine on all my applications written using NRF5.
I am now trying to port these applications to NRF Connect. In creating the Client service for my application, I used NUS as the template and created my client service.
I have tried but I cannot get a sample application work. The Service responds to a Server advertising and connects to it. However when initiating service discovery it crashes.
I include several files which contain the Client service and the application I am using to test with.
I am using NCS 2.0 on a nrf52840dk_nrf52840 dev kit.
The attached file Application.zip contains the files used to build the application and error.txt shows the error I get. It simply appears to crash
