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

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?

1) Yes, this should be possible. You would need to update the application to be mesh compatible. Beware that you will need to do all future DFUs over BLE, as the BLE bootloader does not support Mesh DFU.

2) Yes, a proxy node is essentially a translator node that can communicate with the mesh network & with a GATT BLE based device such as a smartphone.

1) Say we have a regular SDK device in field. Can we upgrade it to Mesh without using JTAG? We want to upgrade it to Mesh in field over the air.

2) By proxy node you mean a node that converts Mesh protocols to regular BLE?

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.
