Don't understand BlueZ 5 GATT interface

Hello - I'm trying to write a GATT client using BlueZ 5.19. Neither Python nor glib are available in my environment, so I'm reduced to using libdbus. I understand that I call Bluez's RegisterProfile method to specify the UUID of the profile/service that I want to connect to, and that when a matching remote device is found, Bluez will call my NewConnection method. (This currently isn't working for me, but that's a different question, posed in an earlier email.) The NewConnection call passes a file descriptor that I use to talk to the remote device. Then what? What do I send over the connection in order to, for instance, read and write an attribute? Link layer messages? ATT protocol commands? Thanks! - Dave Beal dbeal@cardinalpeak.com Cardinal Peak, LLC
