Trying to follow Getting started with nRF5340 and I can't send/recv data. Connects ok.

As the description states, I am stepping through this tutorial developer.nordicsemi.com/.../nrf5340_gs.html

trying to learn about the nRF5340 and the new tools and everything works up to and including connecting to my Android device (the Connected LED comes on and the Phone log shows connected).   Using the Serial Terminal in nRF Connect for Desktop, I connect to the DK and, after pressing reset, I get a message that Zephyr OS has started (see attached screenshot) but when I type in "Hello" and hit send, nothing arrives at the phone.  I also tried the UART in nRF Toolbox on the phone.  Same thing, I can connect, but no data is transferred.

I can query the remote RSSI value and get a response (show in phone log), but no txt exchange.  I'm sure this is something really dumb since everything else seems to work, but before I go further into the hole with my own code, I'd like to know why this isn't working.

TIA,

Tom
