Hi,
Need help in bringing up BLE Mesh on CYW43455 module.
Below is the required mesh setup scenario:
- Create one CYW43455 (Device1) module as unprovisioned node. So that it will send beacons with Mesh supported data.
- Using meshctl on other CYW43455 (Device2) module will perform scan and provision the scanned device (Device1) to form a Mesh network.
Currently able to scan unprovisioned nodes of nordic (nRF52833-DK) devices on CYW43455 using meshctl.
But not able to create CYW43455 module as unprovisioned node.

Please share us the steps to create Mesh network among CYW43455 devices using Bluez on Linux platform.
Solved! Go to Solution.

Hi,
Thank you for providing the details.
Currently, we do not have a ready solution available. But, we have a plan to support it, hopefully towards the end of the year.
Thanks,

Hi Manoj,
CYW43455 does not support SIG mesh.
"Currently able to scan unprovisioned nodes of nordic (nRF52833-DK) devices on CYW43455 using meshctl." -> Which SDK version and applications are you using?
Thanks,

Hello DheerajP_41,
Thank you for the response.
We are using bluez5.52 package on Linux V4.9.87 platform.
bluez package has an inbuilt tool meshctl used for provisioning the unprovisioned nodes.
So we need any sample application on Linux platform to create Unprovisioned Nodes that will broadcast Mesh Information and will be used by the Provisioned to add the device to Mesh Network.
Below is the log output of discovering unprovisioned nodes on CYW43455 using meshctl tool:

Hi Manoj,
Just want to confirm if I understand it correctly. Your use case really require a bunch of BT/WiFi combo modules with MCU running Linux/BlueZ to build BT mesh between them. Right? Normally a provisioner will be BT/WiFi combo, but all other devices are BT only. Cypress indeed provide a bunch of different modules like that.
Thanks,
Victor

Hello VictorZ_46,
Thank you for the reply.
You are right we require to establish a mesh network between multiple devices (CYW43455).
Please share us any applications available on Linux Platform.
