From my experiment,
I’ve used
OcPlatform.setDeviceId(getBytesFromUUID(UUID.fromString("AA323232-BB32-CC32-3232-DD3232323232")));
to a device with SVRs database "deviceuuid":
"32323232-3232-3232-3232-323232323232" successfully.
And OcPlatform.getDeviceId() ==> (AA 32 32 32 BB 32 CC 32 32 32 DD 32 32 32 32
32) OK
But the next time, OcPlatform.setDeviceId() are not allowed to change
"AA323232-BB32-CC32-3232-DD3232323232" back to
"32323232-3232-3232-3232-323232323232"
Because of:
E/OIC_SRM_DOXM: This device owned by owner's device.
E/OIC_SRM_DOXM: Device UUID cannot be changed to guarantee the reliability of
the connection.
W/OIC_SRM_DOXM: SetDoxmDeviceID: cannot set doxm: owner and rowner uuid, revert
D/OIC_SRM_DOXM: SetDoxmDeviceID OUT
Maybe this method should be deprecated for safety.

Subject: Re: [dev] Android, failed to set device ID
Thank you for your kind comments.
As I mentioned, I think, IoTIvity supports the function for changing the ID
using OcPlatform.setDeviceId.

Hello
To my best knowledge, there is no way to set the device ID programmatically.
The way it works - is to change the "deviceuuid" value in "doxm" section of
the security settings file loaded upon platform initialization.
In the server samples, look at file named oic_svr_db_server.json (JSON format)
and oic_svr_db_server.dat (samme file encoded to CBOR, this one is actually
used by the API).

Hello, IoTivity developers,
I am working on an Android based IoTivity project.
I need to fix the device ID of IoTivity platform.
I used OcPlatform.setDeviceId to set the device ID,
but it shows runtime error (UUID length, format are OK).
is there some other solution?
Regards
