ATT BEARER

Question

hi 
 
 what is meant by ATT bearer ?

Thanks for the screenshot. If you take a look at the same document, pg 2276 section 5.2 says this about the ATT Bearer: "the ATT Bearer is the Attribute L2CAP fixed channel". It is also referred to as the logical link in Section 5.1 on pg 2275. The best definition is most likely in Section 2.4 Profile Fundamentals on page 2224. The ATT Bearer is the Attribute Protocol L2CAP channel.
