Want to know the speed of the nrf54 series device firmware update

[Nagajans]

We evaluated the BLE Mesh DFU performance on the nRF52840 and observed that transferring a 342 KB binary took approximately 36 minutes. This aligns closely with the documentation provided on Nordic’s website. We would like to confirm whether the DFU speed for the nRF54 Series remains around ~1 kbps, or if higher throughput can be expected.

Hi,

In the case of Thread, there is no single unified way as to how DFU can be done. For example Matter defines it's own Matter OTA way, though customers may implement something proprietary on top of IPv6.

In general the throughput on Thread highly depends on the used communication scheme e.g. UDP/TCP, strategy on confirmation and packet sizes, topology of the network etc.

For basic usages we would say it could be between 8kB to 11kB per second.
