How to improve mesh dfu transfer (nRF52833)?

[Tomlee]

Hi

   When I  use mesh dfu feature to update devices,   It is very slow (150K , almost takes 60min)

   What can I configure to improve mesh dfu speed, please?

Hi

This is done in the nrfutil call when you start a DFU transfer. Each DFU packet is transmitted after an interval that can be changed by using the -i option while starting the DFU. High interval values are recommended for dense networks with a lot of noise, as this gives more time for devices to recover missing segments/packets. Please note that reducing this interval below 60 ms can result in termination of the DFU process due to packet loss.

Best regards,

Simon
