@Daniel could you try out the bluez package from the following PPA: https://launchpad.net/~waveform/+archive/ubuntu/pi-bluetooth/+packages ?
Should be as simple as doing: sudo add-apt-repository ppa:waveform/pi-bluetooth sudo apt update sudo apt upgrade The version in that PPA contains the pi foundation's patches to bluez which were necessary to enable bluetooth on the pi400 (LP: #1903048), but they also alter some of the general initialization of the bluetooth module on all pis (amongst other things). A (slightly tidied up) variant of this is currently intended for hirsute, to be SRU'd to groovy and focal, so I'd be interested to hear if it also fixes this issue. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to bluez in Ubuntu. https://bugs.launchpad.net/bugs/1901272 Title: Can't connect Bluetooth devices after reboot - Ubuntu 20.10 on Raspberry Pi 4 Status in bluez package in Ubuntu: Incomplete Status in linux-raspi package in Ubuntu: Incomplete Status in pi-bluetooth package in Ubuntu: Confirmed Status in bluez source package in Groovy: Incomplete Status in linux-raspi source package in Groovy: Incomplete Status in pi-bluetooth source package in Groovy: New Bug description: Raspberry pi 4 4Gb ram Ubuntu desktop 20.10 64 bit After reboot no Bluetooth devices connect, scanning Bluetooth devices works, results with same device name (duplicated and with not set up status).
