I have installed an Ubuntu-Mate 20.04 on a raspberry pi4 4gb memory. LibreOffice is included in the package. I wanted to make a small computer for school presentations. Bluetooth is working between the rpi4 and the smartphone. Can transfer files between the pi and smartphone without any problem. But when using the remote controller on Impress (enabled in Tools-Option-Impress-enable remote) I get “Connection failed” message. I have Impress Remote installed in the smartphone. Need help to resolve this issue, please.
