What changes for mesh dfu in nrf5_SDK_for_Mesh_v4.0.0?

[ZHENGXIANG]

Hello:

I am now working with nrf5_SDK_for_Mesh_v3.0.0 and I try to implement OTA for mesh dfu. However, I found that the v4.0.0 has a dfu_no_serial_nrf52832_xxAA_s132_7_0_1.emProject. Could you please tell what the difference is in the mesh dfu part in it and dfu_nrf52832_xxAA_s132_7_0_1.emProject? Does it mean using no serial version, I can do dfu wireless?

Thank you 

Jin

Hi, 

The dfu_no_serial project is available on both Mesh SDK v3.0 and SDK v4.0 . It's not new in SDK v4.0

The main difference in dfu_no_serial_nrf52 and the dfu_nrf52 is that the dfu_nrf52 has support for receiving the image via UART. When the dfu_no_serial can only receive the image via mesh. 

Note that they are not the bootloader, they are the application. You still need the bootloader for the DFU process to work.
