Hi, I'm trying to figure out how to register a custom profile + service(s) using BlueZ in my C app. I found some posts mentioning gatt_service_add() and suggesting to look at gatt-example.c. I checked that file and it seems to be part of "plugins" with BLUETOOTH_PLUGIN_DEFINE in it. In "Doing Bluetooth Low Energy on Linux" pdf I read that plugins are deprecated and I should focus on D-Bus API. Is that correct? Should I avoid gatt_service_add()? Looking further I found https://people.csail.mit.edu/albert/bluez-intro/c404.html This example seems to be using hci_* functions (like hci_get_route() and hci_inquiry()) from libbluetooth.so. I checked hci_lib.h and found nothing related to registering profiles/services. What exactly is libbluetooth? Is that for GATT client purposes only? Finally I started looking for D-Bus API info. In "Doing Bluetooth Low Energy on Linux" pdf there is a RegisterApplication() mentioned. I can see that also in doc/gatt-api.txt. Is that the new D-Bus API I read about? Is there some tutorial/example for it I could use? -- Rafał
