My Bluetooth keyboard is getting disconnected repeatedly. When I press a keystroke, keyboard tries to connect to the laptop but after it connects, it get disconnected immediately. My laptop has Intel Corporation Wireless 8265 / 8275 WiFi/Bluetooth adapter.

Here are some information about the keyboard that I'm trying to connect

I suspect its an issue with bluez or btusb kernel module. My keyboard works fine on my iPhone, Android device and on Windows.

  • uname -rs Linux 5.11.0-22-generic
  • bluetoothd -v 1 5.56
  • modinfo btusb version: 0.8

Edit

I updated Linux kernel to newer version and bluez was compiled and installed from the source. But the issue still persists.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
