Not able to do any operations on bluetooth after getting below error.

If I do "hciconfig hci0 reset", then bluetooth will start working fine.

Hi Maxim,

Thank you for the quick response.

By looking into the comments and changes on shared link, we have a different issue.

We are using "Marvell combo (WiFi and BT) module using SDIO" card.
While connecting/disconnecting a device/headset multiple times, we are facing "Can't read local name on hci0: Connection timed out (110)" issue.

Bluetooth Controller: 4.2
Bluez: 5.49
kernel : 4.4.11

Verified below commands, when we got this error.

#hciconfig -a
hci0:	Type: Primary  Bus: SDIO
	BD Address: AC:3F:A4:CE:38:8F  ACL MTU: 1021:7  SCO MTU: 120:6

#hcitool scan

and on "hcidump -Xt" also no logs.

Thank you in advance.

Oh, yes. You have SDIO bus. My patch fix usb hub.

But SDIO controller can be connected over USB :) Check it.
Comment 8 Uday 2018-05-24 11:53:49 UTC 
No. We are not using USB. We are using SDIO interface directly.
