I' m using the nRF51 Dongle (PCA10031) for the evaluation of the OTA DFU bootloaders of SDK15.0.0 with the NRF52840 PDK.
Using the PC tool nRFConnect V2.3.2 with the App Bluetooth Low Energy V2.1.0 the download speed is much higher than using nrfutil (V3.5.1) dfu ble -ic NRF51 -pkg dfu_app_test.zip -p COM4 -n "DfuTarg" -f.
I have seen, that nRFConnect is using Connectivity firmware V1.2.2 with 1Mbit/s on the nRF51 Dongle, while nrfutil is using Connectivity firmware V1.2.0 with 115,2kbit/s.
Is there a possibility to speed up the download with nrfutil?
A other question to OTA DFU with a bonded target device with nrfutil:
The first OTA DFU with bonds ist working fine with nrfutil. But if I try to program the same target device a second time, it won't work.
Is there a possibility to use bonded OTA DFU with nrfutil repeatedly on the same target device?
Best regards
Roland
