Hi everyone,
I=E2=80=99ve just seen that you added support for mesh in bluez. Nice!
I wanted to know if building a mesh network is tricky or not for the
moment. I already made a mesh network with NRF24L01 chips.
I would like to switch to BT and bluez for future work, but has no
experience in BT (anyway, always happy to learn).
My setup would be meshing C.H.I.P
(https://docs.getchip.com/chip.html#chip-hardware) together (chipset
RTL8723BS)
And raspberry pi 3. Both looks like supported by bluez and are >=3D4.0
BT. Does it worth it to give it a try?
Is the mesh specific to some hardware or any >=3D 4.0 chip does the job?
Thank you for your answers.
kind regards

Pierre-Henri,
The way Bluetooth mesh was designed to work is using advertising bearer. =
This allows mesh nodes to communicate by sending short bursts of data, =
allowing for effective and power-efficient communication.
There is also another bearer, used by the devices that cannot send and =
receive advertising packets in controlled way, like mobile phones. This =
bearer uses GATT connection to the mesh node that offers a service =
called GATT Proxy. Such a node is able to receive mesh messages tunneled =
over GATT connection and forward it to the mesh network using ADV =
bearer.
I'm not a BlueZ specialist but from what I can see, it supports just the =
GATT bearer. So you can use it to talk to "real" mesh nodes, but not =
really to be such a node.
Hope this helps,
Michal Hobot
