BlueZ, controller not working with every bluetooth services but some of them yes

tz flag

I'm not really advanced with linux but this seems like a beginner problem I can't solve.

I have a controller ( BLE controller running Zephyr hci_usb sample ) and it only works with a couple bluetooth services but not some others.

Here are the results I'm getting when I'm trying to find it and if I can scan with it:

hciconfig ( no BD address )

$ hciconfig
  hci0:   Type: Primary  Bus: USB
    BD Address: 00:00:00:00:00:00  ACL MTU: 27:7  SCO MTU: 0:0
    UP RUNNING
    RX bytes:1593 acl:0 sco:0 events:88 errors:0
    TX bytes:285 acl:0 sco:0 commands:51 errors:0

bluetoothctl ( has a BD address ) Scan does work

$ sudo bluetoothctl
  Agent registered
  [bluetooth]# list
  Controller EB:XX:XX:XX:XX:XX BlueZ 5.50 [default]

btmgmt ( finds the controller ) Scan does work

 $ sudo btmgmt --index 0
   [hci0]# auto-power
   Found controller with index 0
   [hci0]# find -l

hcitool ( Doesn't find the controller ) Scan doesn't work

$ hcitool scan
  Scanning ...
  Inquiry failed: Operation not supported

btmon

$ sudo btmon

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.
