I was following the bluez docs to access the gatt-services via bluetoothctl command.
https://core.docs.ubuntu.com/en/stacks/bluetooth/bluez/docs/reference/gatt-services
The gatt server was running on a raspberry pi and I was trying to read a service from ubuntu core running on DELL 3001 gateway. However the command select-attribute was not available. Is the documentation correct?
Below are the logs for the reference.
