Mesh testing with nrf52840 development kit

[suprithams]

Hello, we are trying to test the mesh functionality with nrf development kit. We erased the flash on the dev kit and we programmed it with softdevice version s132v3.0.0. And then we programmed the mesh application version nrf51sdk_8.1.0 and then when we run the python script for the ping_pong example mesh, we are seeing the following messages:

Assigned handle 0 to COM14 Assigned handle 2 to COM15 Failed to establish connection to COM3 (handle 1)

This seems correct. How to test the mesh functionality? When we turn on the Bluetooth in our android phones to see these dev kits, we do not see any names on nrfConnect. How to see these devices on the app in an android phone (with Bluetooth turned on)? Are we missing anything? Any help is really appreciated.

Hi

If the mesh is working you should be able to see the packets, assuming you haven't changed the BLE access address from the default.

I just programmed the BLE_Gateway example into the nRF52, and immediately saw the advertise packet in nRF Connect as shown here:

The example I used was this: \nRF5_SDK_12.0.0\examples\nrf51-ble-bcast-mesh\nRF51\examples\BLE_Gateway

I just chose the target for the nRF52832, and removed the MESH_DFU define since I didn't install the bootloader.

Best regards

Hi Torbjorn, It is possible to program nRF52840? And could you explain how to removed MESH_DFU? I really want to test mesh funcionality :)

Hi

If you are looking to work with mesh I would recommend switching over to our Bluetooth mesh solution, which will see continued development going forward (openmesh was more of a temporary solution while we were waiting for the Bluetooth mesh specification).

We don't have nRF52840 support yet, but it is in the works and will likely be a part of the next release.

Best regards
