Hi!

I adapted example-gatt-server for a project... and it works ok
(thanks), as long as public address is used. I could not configure
random address in main.conf, so I'm doing it with btmgmt:

#!/bin/bash
(
    echo power off
    sleep .1
    echo le on
    sleep .1
    echo bredr off
    sleep .1
    echo static-addr c2:34:56:78:90:ab
    #echo public-addr 00:1A:7D:DA:71:11
    #echo static-addr c2:34:56:78:90:ab
    sleep .1
    echo connectable on
    sleep .1
    echo pairable on
    sleep .1
#    echo discov on
    sleep .1
#    echo advertising on
    sleep .1
    sleep .1
    echo power on
) | sudo ../bluez/tools/btmgmt
sleep 2

With random address, it does not work: lescan from other machine
detects right address, and I can connect, but that's it, services
can't be listed.

I'm using 4.19 kernel on one side and current -next on the other side,
with bluez e4cf43fc62b4e4dbabc72d4e44e095d7a9087992, Fri Sep 7
16:25:44 2018.

And it seems I'm not the only one having this problem:
https://stackoverflow.com/questions/50707914/setup-bluez-gatt-server-with-r=
andom-address

Any ideas how to debug that? Does configuration with random address
work for you? Is there chance update to latest versions helps?

Thanks,
									Pavel
