Are the UUID's generated with nRFgo valid?

[Marcel Mulder]

Hi,

I just took a look to nRFgo to see how it generates vendor specific UUID's. It looks if they are generated completely random including the version number. According to RFC4122 the UUID string had the format of:

xxxxxxxx-xxxx-Vxxx-xxxx-xxxxxxxxxxxx

where V is the version number of the UUID. For random generated UUID this should be 4. If i look to the generated base uuid's in nRFgo than the V part is also random. I think you end up with an invalid UUID or am I wrong?

You are correct, the UUID generated does not appear to be a Version 4 UUID. However this does not mean that the number generated is incorrect , it however does not conform to the Version 4 UUID convention. You can edit the number created to match the Version 4 UUID. i.e. using the nRGgo studio as a random number generator.

The UUID must comply to ITU-T Rec. X.667 | ISO/IEC 9834-8 (technical equivalent to RFC4122) according to Bluetooth specification. Therefore I think it is incorrect to assume that the UUID generated by nRFgo are correct.
