I would like to be able to read and send SMS messages on my Samsung phone from my Ubuntu laptop through bluetooth interface and kdeconnect software.

The ‘KDE Connect Settings’ app in Ubuntu laptop is able to see the phone in a paired status.

The ‘KDE Connect’ app on the Samsung phone is unable to see the device corresponding to Ubuntu laptop.

On the laptop, when clicking on ‘Send ping’ button inside the ‘KDE Connect Settings’ app, nothing happens.

Running KDE Connect app version 1.32.5 in Samsung phone.

Using kdeconnect package version 1.4-0ubuntu5 on Ubuntu
OS version 20.04.6 LTS.

Bluetooth interface enabled in laptop:

$ bluetoothctl show | grep ‘Vendor specific’
UUID: Vendor specific (00005005-0000-1000-8000-0002ee000001)

See these messages in /var/log/syslog in laptop:

    Nov 24 12:21:23 adyar org.kde.kdeconnect.daemon.desktop[2518]: kdeconnect.core: Sending onNetworkChange to 1 LinkProviders

Sorry I can’t provide a “I know this one”-fix, but have you checked if all the BT protocols are in enabled in your phone’s BT settings?
Once I pair my Android with the computer, I can see the pc as connected device in Android’s bluetooth settings. It has a gear icon next to it to get to settings for this specific connection. Here I have protocols for HD audio, phone calls, media audio and contacts sharing, to toggle individually. Maybe one of these being off hinders full connectivity between the devices.
