Changing discoverable on succeeded

It is unclear what you want. Do you wont to make it discoverable? Then why you try to scan? Making the adapter discoverable means that it becomes scannable by OTHER devices. — Pilot6, Jan 26 '21 at 10:27
Yeah you are correct @Pilot6 the in-built bluetooth adapter is not finding any device nor discovereble to any other device. — Piyush Mhatre, Jan 26 '21 at 10:29
So what is the device? Please [edit] your question and add output of lspci -knn | grep Net -A3; lsusb terminal command. — Pilot6, Jan 26 '21 at 10:30
This device is poorly supported by Linux. It is a very old device. There are alot of questions with some solutions. Some work now, some don't You can search by your adapter RT3290 — Pilot6, Jan 26 '21 at 10:39
Yeah I have searched a tons of solutions and they didn't worked and came to know that there are many bugs but I am confused that which one is correct and how to fix them even if I identifyed it, can you help me something about it ?@Pilot6 — Piyush Mhatre, Jan 26 '21 at 10:43
I suggest you add what you tried and did not work (with the corresponding output you get, if appropriate). — sancho.s ReinstateMonicaCellio, Jan 31 '21 at 09:35
I have given everything ,bluetoothctl command, in it the scan on command should find all discoverable devices but its giving an error , now which extra details should I give to you. Ok you suggest me that what info should I give. @sancho.sReinstateMonicaCellio — Piyush Mhatre, Jan 31 '21 at 11:31
