Hi there,

Very interesting but this is it working on nrf52832 chip ?

I think Nordic missed a usecase:

I still make the slots equal in size, this way mcuboot can support revert. But the size of the DFU that must be transferred (e.g. over BLE mesh) is 30% smaller.

Hi Ali,

Great article, thank you! I'm curious - how is it possible to achieve a data rate of 60.5 kB/s during DFU? I’m using nearly the same settings as you, but my data rates don’t reach that level. Do you think it could be due to the device I'm using for the update (my phone), or might it also be related to the difference between your SoC (nRF54L15) and mine (nRF5340)?

Hi Shahin97,

I'm using "ncs\v2.8.0\nrf\samples\nrf_compress\mcuboot_update" this routine running in nRF5340-DK.After connecting the Bluetooth, select the DFU screen and select dfu_application.zip to upgrade.But after the selection, there is no transfer progress, no other printing on the serial port, it seems that nothing happened

Could this be used with ble mesh dfu?
