I am trying to open a bluetooth mesh network with my Raspberry Pi and a Qorov DWM3001CDK dev board where I run a Zepyhr RTOS.
I like to work with Python to do that so I got the bluetooth-mesh package for that. (https://github.com/SilvairGit/python-bluetooth-mesh)
For testing I also tried this package: https://github.com/dominikberse/homeassistant-bluetooth-mesh
When I am scaning for unprovisioned devices I can find my DEV board. But when I am start the provision process it always ends with an bad-pdu error.
The same result I got when I use the bluez mesh-cfgclient. The system says that it like to get an hexadecimal key and than after a few seconds I get the bad-pdu
There Termial ouput looks like:
Unprovisioned devices:
UUID: C713030EB87D4B90B5E70A51E8AA8E66, RSSI -67, Seen: Sat Jan 21 16:55:00 2023
[mesh-cfgclient]# provision C713030EB87D4B90B5E70A51E8AA8E66
Provisioning started
Request hexadecimal key (hex 16 octets)
[[mesh-agent]# ] Enter key (hex number): Provisioning failed:
[[mesh-agent]# ] Enter key (hex number): UUID = C713030EB87D4B90B5E70A51E8AA8E66
[[mesh-agent]# ] Enter key (hex number): bad-pdu
[[mesh-agent]# ] Enter key (hex number):
The bluez log looks like:

The Zepyhr log tells me this when the error apears:
<wrn> bt_mesh_prov: Unexpect msg 0x09 != 0x05
There is also no key output that I can use to work with.
Thank you very much for your help.
