bluez meshctl error: socket operation on non-socket

bluez meshctl error: socket operation on non-socket

[Venkat Vallapaneni]

Hi,

I am trying to use bluez 5.52 for provisioning a bluetooth mesh capable 
device. When I gave provision <uuid>, I get this below error. Please let 
me know what I am missing.

I am using ell 0.26 on ubuntu 18.04. I am able to provision successfully 
with bluez 5.50.

AcquireWrite success: fd 8 MTU 69
GATT-TX:     03 00 10
*sendmsg: Socket operation on non-socket*[Zephyr]#

Rgds,
Venkat.

Hi Venkat,

Are you attempting to provision a device that requires PB-GATT provisioning?  If so, the bluetoothd daemon must be up and running. However, this tool is old, and will probably be deprecated at some point.

However most Mesh devices should support Advertising based provisioning.

The Mesh daemon (Bluetooth-meshd) and the mesh-cfgclient tool (in the tools directory) has been undergoing modification even since v5.52, so you will want to checkout the tip.

./tools/mesh-cfgclient is the tool most appropriate for mesh development today.

Hi Brian,

Thanks for the response. Yes, I am using PB-GATT barrier. With 
bluetooothd running, I am able to provision my device.

I also tried mesh-cfgclient but unsuccessful. I launched the shell with 
mesh-cfgclient (with bluetooth-meshd running) and I gave create command 
in the shell. I see segmentation fault. Any steps I am missing?

Is mesh-cfgclient only for provisioning or also for sending mesh 
messages also?

Rgds,

Venkat.

Ok... well if this is specifically to play with Zephyr, you can build it to accept PB-ADV based provisioning as well. But i think Zephyrs mesh tip is PN-GATT by default.

Are you on the tip of both the BlueZ tree, and the ELL tree? Also, what linux distro are you using?

> Is mesh-cfgclient only for provisioning or also for sending mesh messages also?

mesh-cfgclient not only provisions devices with PB-ADV, but it also is a full featured Config Client. It can send keys, bindings, subscriptions, and publications.

I've successfully provisioned the zephyr onoff-app with both meshctl
and mesh-cfgclient.

However, when installing meshd, I found that you have to enable
bluetooth-mesh with systemctl or I get this when I issue the "create".

Re: bluez meshctl error: socket operation on non-socket

[Venkat Vallapaneni]

Yes, if I run bluetooth-mesh daemon with systemctl, I am able to execute 
create successfully but if I run the daemon with sudo manually, create 
crashes.
Any order dependencies for daemon that are broken when run manually but 
honored with systemctl?

Rgds,
Venkat.

The debug output indicates that the daemon started, but hasn't found an
available hci device, so it is stuck in semi-initialized mode:
the dbus-service name has been registered, but not the interfaces.

There are multiple thins going on here:
- Currently bluetoothd & bluetooth-meshd cannot run on the same
controller (addressing this requires kernel changes). So if there is
only one controller it's either bluetoothd or meshd daemons, but not
both. Please check if bluetoothd is running.
Perhaps, with systemctl meshd starts before bluetoothd starts and grabs
the single hci device?

- mesh-cfgclient needs to have an additional check for Network1 being
detected. This would deal with the symptom not the reason.

- I believe the daemon should be fixed so that d-bus service is not
exposed unless there is a BT controller available. Will look into this.

Best regards,

Inga
