BLE Mesh DFU - which bootloader to use with nrf52840?

[Mitch996]

Hello: I'm about to test out the ble mesh dfu, and to do that I need to flash my device, which is nrf52840, with precomped bootloaders.

Now here is the problem: Which one should I choose? They are device-specific and the closest I can get is "bootloader_serial_nRF52832_xxAA.hex" should I go with it?

Edit: in case there isn't - can I compile one myself?

@thomasstenersen can you please help me... again?

You are right the precompiled hex files are device-specific, i.e. you won't be able to use any of the precompiled bootloader images on the nRF52840. The nRF5 SDK for Bluetooth Mesh does not have any support any support for the nRF52840 yet, so compiling it yourself would require changes to the CMake and Ninja build system of the release, which I have not attempted.

@bjorn-spockeli Hello, can you please tell me when will a release be available?

If you are not in the position to disclose that information, please either PM or post the email for the individuals who can of the Nordic headquarter in Norway. My previous contact with our regional sales office yields nothing beyond formulated response.

@mitch966: I am afraid that I do not know when a new version of the nRF5 SDK for Bluetooth Mesh is going to be released. All information regarding roadmaps and release schedules goes through our sales organization so if your local RSM cannot give you a date then its likely because this date has not been fixed yet.
