Mesh add ble dfu service

[zero]

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?

Hi ，

1.Change NRF_FSTORAGE_SD_QUEUE_SIZE 4 to 64, it still has no effect, please help confirm where to change?

<t:          0>, main.c,  522, ----- BLE Mesh LPN Demo (Updated) -----
<t:          0>, app_error_weak.c,  119, Mesh error 4 at 0x000274C7 (E:\Nordic\nrf5_SDK_for_Mesh_v3.1.0_src\examples\common\src\ble_dfu_support.c:148)

2.Modify the flash_placement file , and add RAM_SIZE=0xc260 to common. Still there is error 4.

.

How do I allocate more memory to DFU?

Hi,

To perform DFU over BLE update for the Low Power node example, you must build and program the Secure Bootloader example. Have a look at the the guide here.
