I used the example in "SDK_2.2_QN908XCDK\boards\qn908xcdk\wireless_examples\bluetooth\private_profile_client(server)"
You can check the Wireless UART project as a base as it has already added the multiple connections support, there you can find the differences in the project configurations.
If after checking and comparing both projects you still have doubts or problems, just let me know.
Thank you for your help!
