Hello,
I am trying to figure out why I'm getting "Command Disallowed" for the HCI
commands "LE Set Advertise Enable" and "LE Set Advertising Parameters". I've
been trying for a few days to get a GATT service running; first with the D-BUS
API, which occasionally worked but was very unstable. Now I'm trying with HCI
directly with the pybleno / bleno libraries.
I have bluetoothd disabled and I have tried an `hciconfig reset` and reboot.
Unsure what else I can do, I'm asking here.
The errors are these:

Any help / pointers is much appreciated.

Hi Devin,
If I recall correctly, you get this if advertising is already enabled.

For the first error (Advertise Enable), this makes sense. I also saw that on
another host which seemed to be working.
But the following seem to prevent advertisements from being sent:

You also need to ensure you are not mixing with extended advertisement
commands, iirc if the stack does send
BT_HCI_CMD_LE_READ_NUM_SUPPORTED_ADV_SETS it would already prevent the
legacy version to work. Bottom line here is, either use entire stack
or switch to user-channel with a proper stack, mixed handling won't
cut anymore, and for the most part we should be covering all the
advertisement features over D-Bus if we don't please let us know if
there are still gaps.

Hi Luiz,
I am not sure what you mean about mixed handling, but I am not using bluetoothd.
As you can see the entire log, I don't see any indication of
BT_HCI_CMD_LE_READ_NUM_SUPPORTED_ADV_SETS. Could that be a default from boot
that I need to disable?
BTW, what is "user-channel with a proper stack" ?
My issue with the D-BUS API is that I could never get reliable behavior of even
basic discovering and connecting; it's not about missing features.

It would be good to see the complete log from when the "Reset" command
is issued, otherwise we don't know in which "state" the controller is
in at the various commands. Also widen the command window when running
btmon so we see the complete names. :)
Seeing the result from "LE Read Supported States" would also be nice.

Hi Emil,
below is the complete log, starting with the the reset command. It
includes the "Supported States" call too. Let me know if there is
anything else I can do.

It's as Luiz said, you're mixing two different stacks and hence mixing
legacy advertising commands with extended ones. The HCI standard says:
"If, since the last power-on or reset, the Host has ever issued a legacy
advertising command and then issues an extended advertising command, or
has ever issued an extended advertising command and then issues a legacy
advertising command, the Controller shall return the error code Command
Disallowed (0x0C)."
After Reset, you can see "LE Set Extended Advertising Parameters"
during the `hciconfig` runs. Then later, when `python` runs, a "LE Set
Advertise Enable" is sent. This is disallowed behaviour.
One solution is that your python program sends a "Reset" command as
the first thing, otherwise you don't know which state the controller
is in. The other solution is to use BlueZ only.

Thanks Emil,
that did help and I was able to finally get a basic service working. I
would be happy to use BlueZ but I was never able to get discovery /
connection to work more than 10% of the time, so that's why I'm trying
something else.
I was also getting disconnects every 3 seconds from an unknown source. I
think I fixed that with the module parameter enable_autosuspend=N.
This was also a subsequent "Set Extended Advertising Parameters"
command. These aren't sent from my program and nothing running on my
system seems to be talking to bluetooth.
Is this part of the BlueZ stack that's running in the kernel?
Can it be disabled?
