Mesh add ble dfu service

Question

Based on mesh3.1 sdk15.2 Can I add DFU service to light switch server? Used to upgrade firmware via APP nrf Connect? I added a dfu service to the light switch server with the following error: mesh assert at 0x002D4A2 
 
 How to solve this problem?

Currently we haven't implemented a solution for doing OTA DFU with nRF Connect. I think is possible to implement this yourself, but the easiset way is to do DFU over a serial interface for mesh right now. You can have a look at this post . 
 Edit: We do have an example that uses BLE DFU. Have a look at this example , it will give you an idea on how to implement this.

Hi Mttrinh 1. Open the nrf5_SDK_for_Mesh_v3.1.0_src\examples\experimental_lpn example 2. Change #define BLE_DFU_SUPPORT_ENABLED 0 to 1 3. Compile the project 4. The debug log is as follows: 00> , main.c, 521, ----- BLE Mesh LPN Demo ----- 00> , app_error_weak.c, 119, Mesh error 4 at 0x00000000 (:0) I have not made any changes to this project. Why do I get this error with dfu? How to solve it?

Hi, 
 Error 4 is NRF_ERROR_NO_MEM. You need to allocate more memory for the DFU.
