Fixed_Pin change between connections

Curious regarding using ACI_GAP_SET_AUTHENTICATION_REQUIREMENT to change the fixed pin after already using a different pin key for a previous connection.

Would that work?

Any bad consequences?

Hi DS.4,

It's important to make sure that you are not in a connected state when changing the fixed pin.
This should work and not cause any problems.
Don't hesitate to let us know if it worked ;).

Changing it after I complete bonding , and it looks fantastic.

So next connection does get to use the new key. So far so good!
