I would like to access GATT profile from C program using Bluez
I think that it is possible to read / write to the gatt profile using the "hci_send_req" function or the "hci_send_cmd" function.
However, we can not find the parameters that set the data.
Is it connected to the terminal of BLE and read / write to Gatt profile is not prepared?

First of all, I investigate whether it can be realized from the command line.
The environment is RaspberryPi3.
pi@raspberrypi:~ $ sudo dbus-send --print-reply --system --dest=org.bluez /org/bluez/hci0/dev_XX_XX_XX_XX_XX_XX --type=method_call org.bluez.Device1.Connect
Error org.bluez.Error.Failed: Software caused connection abort
Sorry, please hide the MAC address.
With the gatttool command, connect, primary, char-read-hnd, and char-write-req (cmd) are possible terminals.

Thank you for the information.
I tried, but org.bluez.Adapter1 actually exists, but an error occurs.
pi@raspberrypi:~ $ sudo ./glibtest XX:XX:XX:XX:XX:XX
Adapter is Powered "on"
Unable to get result: GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: Method "ConnectDevice" with signature "a{sv}" on interface "org.bluez.Adapter1" doesn't exist
The existence of org.bluez.Adapter1 is checked with the following command.
sudo dbus-send --print-reply --system --dest=org.bluez /org/bluez/hci0 --type=method_call org.freedesktop.DBus.Introspectable.Introspect
</method></interface><interface name="org.bluez.Adapter1"><method name="StartDiscovery"></method><method name="SetDiscoveryFilter"><arg name="properties" type="a{sv}" direction="in"/>
The version of bluez has been updated from 5.43 to 5.44.

You might want to use the DBus API for this.

You can useConnectDevicemethod if you already know the MAC address of the device. Else you need toStartDiscovery,Trust,PairandConnectin sequence. You can find theConnectDevicemethod example here: gist.github.com/parthitce/eb6b751df3235f7247babc4c9aba41d8. You can also find more examples in gist.github.com/parthitce and explanation in linumiz.com/author/parthiban
