Bluetooth Specification Nightmare

[Stephan Walter]

Hi, we're using an nRF8001. Trying to find the relevant Bluetooth Specifications, we found the following mess (pardon my french!):

• Core Specification 4.0, 2300 pages, June 2010
• 3 Core Specification Addenda, >100 pages each
• 1 Core Specification Supplement
• 3 Errata Service Releases since 2010
• multitude of GATT profile specifications

Is there a single document that describes the current specification we should try to follow?

Which "version" of the Specification does the nRF8001 conform to?

Is there a need to get proprietary profiles certified by the SIG or Bluetooth.org?
