nRF5 to Mesh Upgrade

[Aftab]

Hello,

We have selected nRF solution for our next product line and currently evaluating the software/SDK setup for that.

We are testing following SDKs:

nRF5_SDK_15.2.0_9412b96 and nrf5SDKforMeshv310src.

I have a few questions:

1. If a device is programmed with nRF5 SDK and later we want to upgrade it to Mesh SDK, can we do it through OTA?

2. Once a device is upgraded to Mesh SDK, will it remain compatible with the non-mesh nRF5 SDK devices?

Thanks.

1) Yes, you should be able to upgrade to mesh SDK from the nRF5 SDK. You will need to upgrade the bootloader, as the bootloader is different between the nRF5 SDK & the mesh SDK. You will then also need to use the correct softdevice for the specific mesh version, as well as upgrade the mesh application. However, it seems there may be some issues with upgrading the device page. Also, this seems like quite a complicated operation.

2) If you want to have mesh device compatibility with regular BLE, it might be a good idea to either use the proxy node functionality or integrate mesh functionality in a nRF5 application or vice versa. This way, it will most likely be quite a bit easier to do a DFU of the application code. You would then most likely only need to do a firmware update of the application & not the bootloader and softdevice.

Hello,

We have developed a GATT based application based on nRF5_SDK_15.0 (Bluetooth LE without mesh). We want to add mesh functionality in this code as you described above. The link you shared is not working. Can you please share some more details/documentation how to achieve this?

Hi, could you please open a new devzone case, as this case is quite old.
