drowning in numbers

Hi,

      we are late stage development on NRF52840 with sdk 15.0 and softdevice 6.0. The mind turns to certification. It all seems very complex and confusing

1) Do we need to be members of the bluetooth sig?

2) Do we need to qualify our products?

3) Do we need a company bluetooth Community ID and if so where would we use it?

4) We have a device information service on our product, do we need an IEEE OUI? Can we just take the current random mac and format the system id according to the standard?

5) Can we use a CUI instead of an OUI?

Cheers Paul
