The following seems to works just fine

I'm trying to use this approach for an LTE example with RRC state transition as the trace source. I'm continuing to get errors after trying many variants. If possible, please point me to a template/example that I could adapt for my purpose? Thanks!

I'm attaching a simple version of the code I'm trying using the approach suggested in this thread. This code is failing to connect the callback. Please take a look and see if you can see the error(s).
Thanks,
Shyam
