update local gatt characteristic value using bluetoothctl

Question

I have set up a gatt Server on an raspberry pi using bluetoothctl and BlueZ 5.50 (according to this thread: BlueZ: How to set up a GATT server from the command line) I can connect to the gatt server from an other machine and also read the given value. Now I want to try notify.

The subscription works fine, but how do I update the value on the local gatt server? I can't use select-attribute because my local services an characteristics do not show up in the list that appears when using autocomplete.

Would be nice if someone can help me with this problem.

Answer 1

view the server DB

list-attributes local

select the attribute before performing opertaion on that charecteristic
