Mesh OTA DFU

[mregan11]

I am using nrf52832 with sd 6.0 and sdk 15.0. My application is based on the buttonless DFU example, and I am using a bootloader with OTA DFU. To update the application I need to individually connect with each one of my products. Is there a way to update my current bootloader or application to allow for a BLE Mesh OTA DFU?

Hi. 

The bootloaders are quite different in the way they work. But if you want to do this, you can build your application as a Mesh application (without using Mesh) and then use the normal Mesh DFU update process to update your "Mesh" application. 

Note that you will need to flash the Mesh bootloader instead of the normal bootloader. Also, using Mesh DFU will use 1 hour for a 100kB image. 

Best regards,
