You can see the image. There the bluetooth button is already enabled but it is still turned off. I have tried many solution available in the internet, but nothing works. Please help me because I really need the bluetooth. I am currently using a bluetooth 5.0 dongle.

Here is the output of hciconfig -a:

Please share of the output of `hciconfig -a` on the terminal. Paste the text and format it rather than sharing a screenshot.

The device is `Cambridge Silicon Radio, Ltd Bluetooth Dongle`. It is a noname device with many problems. You can search the site for possible solutions.

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.
