I am working on the nRF5340DK and NCS v1.5.0
Acording to this example https://github.com/NordicMatt/multi-NUS, I used the Throughput sample as the fundermental project. Then after added the Connection Context Library (CCL) , I continue ported the Central HIDS sample in my project with CCL.Here is my project:1602.throughput_hid.7z
And once programming the project to the nrf5340_DK,while programming the Throughput sample to another nrf5340_DK and the Peripheral HIDS mouse to a nrf52840_DK, The central log came like this:

My question is:
1.Whether this way that my project combine the the Throughput sample and the Central HIDS sample with CCL is feasible or not ?
2.If possible,It seemed that the multi-connection exited some problem.What is the reason?
