Ok, it took me a while to figure out that --enable-experimental is
needed.

Then help was playing tricks with me:

For more information on the usage of each command use:
    btmgmt <command> --help
root@...0:/my/bluez-5.26/tools# ./btmgmt public-addr --help
Set Public Address for hci0 failed with status 0x0b (Rejected)
root@...0:/my/bluez-5.26/tools# ./btmgmt public-addr
Usage: btmgmt public-addr <address>


root@...0:/my/bluez-5.26/tools# ./btmgmt public-addr 01:02:03:04:05:06
Set Public Address for hci0 failed with status 0x0b (Rejected)

Hmm. Since setting public address only works when interface is down,
and we lose all the settings during up, this does not work at all,
right?

Anyway, you might want to apply this to lessen the confusion.
