1185**
1186** Parameters       bd_addr - the peer address

1188**                  info    - the BTA specific information (like last active operation).
1189**                  p_offset- the location to receive object offset of the suspended session
1190**                  app_id  - application ID specified in the enable functions.
1191**                            It can be used to identify which profile is the caller
