netkey requirements

[jessevdam]

When configuring a BLE mesh network, one have to set a netkey. Are there any requirements for generating this key or can this be any random sequence of numbers.

Hi.

You can find the requirements for the Network key if you take a look at the Mesh Profile Specification (revision v1.0.1);
3.8.6.3 - Page 112:
The network key (NetKey) shall be generated using a random number generator compatible with the requirements in Volume 2, Part H, Section 2 of the Core Specification.
