as already written in other threads (two years old) the DFU upload with nrfutil is extremely slow.
Transferring the same data from a smartphone (with BLE5) takes about 20seconds, with nrfutil 2 minutes or more.
We use nrf52840 DKs for the PC side and our board.
We use the following command to run the update.
nrfutil dfu ble -ic NRF52 -pkg app_dfu_package.zip -snr $(NRF52840_SNR_BLE) -n "MY_NAME" -f -cd 0
nrfutil version 6.0.0a1
What could be the reason for the slow update. Is there anything we can do to speed this up?
