You can check with &quot;bluetoothd -v&quot;. The gatttool has been deprecated since bluez v5.44, so if you want to stick to gatttool then use v5.43, or just simply use bluetoothctl and do your notification magic there.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/121008?ContentTypeID=1Thu, 15 Feb 2018 16:45:40 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a339d9e2-ef94-4f96-87d8-1a479359c55aMartinBL<p>Hi,</p> <p>I suppose 0x000e is the correct handle to write to, and that 0100 is the hexadecimal value you want to write? I haven&#39;t used ubuntu and bluez gatttool, but are you sure that the value should be least significant byte first? I.e.&nbsp;that it shouldn&#39;t be&nbsp;0001?</p><div style="clear:both;"></div>
