6 years ago I see to be having a similar issue. When I run nRFConnect I also see no services. Here is the nRFConnect trace:

I setup bleno on an Ubuntu 16.04 system and trying to discover the examples/battery-service with the nRF Connect App under Android. The device scan shows the 'Battery' device but no service can be discovered. This is the log of the nRF Connect App:
