BLE Mesh firmware update using UART by the host controller

[Hardik V Patel]

Hi,

We want to update nrf52832 via uart. We have host controller and want to upgrade nrf52832 through it. We have SDK  BLE_2.0.1 for the mesh. I had gone through  DFU Example which is given but not found relevant for us. Basically, we want UART DFU in the SDK  BLE_2.0.1 with the example where we can start. Please help us.

Hi,

Unfortunately, there is no support for DFU over UART in the Mesh SDK.

Unfortunately, no we do not have any plans for that.

Thanks, Mttrinh, For your clarification and quick support,

As I mentioned I need DFU UART for our application but unfortunately it is not available so we have decided to implement our own UART DFU support so my query is as per below,

1)Is it possible to implement DFU UART in this SDK? I want to upgrade hex file over the UART from the host controller for NRF52.

2)Is there any document for DFU? It would be great if you can give us any documents for DFU UART also and bootloader related things where we should be able to start development of DFU UART.
