Hi,
I try to do the DFU example in the nRF5 Mesh SDK V4.0 for the nRF52833 Development-Kit:
Somehow I get this error thrown:
nrfutil dfu serial -pkg app_dfu_package.zip -p COM62 -b 115200 -fc --mesh
Upgrading target on COM62 with DFU package C:\Users\set\Desktop\DFU OTA\app_dfu_package.zip. Flow control is enabled.
Failed to upgrade target. Error is: ord() expected string of length 1, but int found
Possible causes:
- bootloader, SoftDevice or application on target does not match the requirements in the DFU package.
- baud rate or flow control is not the same as in the target bootloader.
- target is not in DFU mode. If using the SDK examples, press Button 4 and RESET and release both to enter DFU mode.
The bootloader and the SoftDevice is correctly installed, as tested with nRF Connect.
Flow Control and baud rate should fit, since I flashed the DFU example dfu_nrf52833_xxAA_s113_7_0_1
I tried to set the device in the DFU mode, but also this seems not to be the problem here.
So I have a few questions about the DFU:
- Is my assumption correct, that the nodes do not need to be in a mesh network directly (no network key necessary), but when they see a DFU package with the correct public key, they will accept it and relay it?
- Where do I need to put the private key, from my understanding I need to flash it on each device, but where?
Kind Regards,
Sebastian
