I am trying to send GATT notification in bluez 5.43 using DBUS. But
currently the gatt-service.c doesn't provide any details how to send
it using DBUS. Currently
static DBusMessage *chr_start_notify(DBusConnection *conn, DBusMessage
*msg, void *user_data)
return g_dbus_create_error(msg, DBUS_ERROR_NOT_SUPPORTED, "Not Supported")
is given like this as no characteristic supports notification in the
given code. But I am trying to build a custom service which has
notifiable characteristics. How should i handle it. What should be the
code that i need to write inside char_start_notify to achieve it.
Hi Barry,
I did look at it. But I want a solution in C and not python. I am not
conversant with Python. How do it convert this into C. I am a beginner
in bluez. Can you help me on this .

Have you taken a look at test/example-gatt-server?
The notifications are done with the PropertiesChanged signal on the
value of the characteristic
https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/doc/gatt-api.txt#n121
https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/test/example-gatt-server#n200
And in the example are issued with:
https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/test/example-gatt-server#n297
https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/test/example-gatt-server#n399
Hope that helps
