Multicast messaging and group messaging

Hello Mynewt Team,


Is it possible to send a broadcast message by one of the devices present in the mesh ?

For e.g. to broadcast a event which happened ? Something like push notification instead of continuously polling for it by a client.

Thanks,
Aditya Xavier.

Thanks Łukasz ! That helped.

Would try that and would ping back incase of problems.

Thanks,
Aditya Xavier.

Hi Aditiya,

Alright, there is no really documentation but you can try it out on our
btmesh_shell app.

There is shell.c file which expose configuration client which you can use
for testing - e.g. you can subscribe virtual address.
You can also trigger sending messages to devices. By playing with "dst"
command you probably should be able to set destination to some group.

Btw.  Since we do not support provisioner role, there is command
"provision" which sets fixed keys so you can create mesh network out of
couple of nodes without the actuall provisioner.

Best
Łukasz

Thanks Łukasz,

Yes I am aware its possible as per the ble mesh spec, wanted to know if there is any documentation / example of using and registering a group address.

Thanks,
Aditya Xavier

Hello Aditya,

It should be possible to do so with a publish model. Group address or
virtual address should help here (see Mesh spec)
