CCS/LAUNCHXL-CC2640R2: Simple peripheral works in BLE but not BLE5

Tool/software: Code Composer Studio

I have two LAUNCHXL-CC2640R2 boards and am experimenting with sample projects.  I program one board with simple central and the other with simple peripheral.  I can see the UART output of both boards in TeraTerm and they can connect to each other.  I can then program one board with BLE5 simple central and the other with BLE5 simple peripheral but this time only the simple central shows up in tera term and the simple peripheral appears to not work.  I can't see it using BLE scanner on my phone and nor can the simple central board see it.

Is there a reason that I don't see any UART output or advertising from the ble5 simple peripheral project but the ble5 simple central project works fine?  Both the BLE and BLE5 versions of the projects are found in the simplelink CC2640R2 SDK version 3.30.00.20.

Thanks.
