Is there a working sample of BLE Mesh on the nRF5340?

[pquevedo]

Using nRF Connect SDK v2.1.0 and the nRF5340 PDK, are any of the ble mesh samples in the fw-nrfconnect-nrf repo working yet? I've tried both the mesh light and light_switch on the app core (readme says the 5340 is supported) and the ble hci_rpmsg on the net core but when I scan for beacons using an Ellisys capture device i don't see anything. The logs from the app_core indicate the device is publishing an unprovisioned beacon periodically without any errors but the only thing the sniffer can pick up are connectable advertising packets for the gatt proxy. 

These samples seem to work fine when running on the 52840 DK. Any guidance?

Hi,

The nRF5340 is supported, but it requires other network core configs than the ones that are by the default.

We don’t have a guide as of now, but it is in the works. What you have to do is to match the BLE-configuration in the controller and the mesh application, like it is described in the nRF5340 User Guide. You need the same feature-set, same L2CAP-buffersize, etc.

Hi,

these lines added to the prj.conf made nrf/samples/bluetooth/mesh/light app working on nRF5340:

# Make BT config the same as of zephyr/samples/bluetooth/mesh
# because that works right with zephyr/samples/bluetooth/hci_rpmsg
CONFIG_BT_TINYCRYPT_ECC=y
CONFIG_BT_L2CAP_RX_MTU=69

Best regards,
