I recently assembled a box for htpc duties, including a bluetooth
keyboard.

It mostly works, except that the hci interface continually powers down.

I suspect every time the keyboard powers down,the hci does, too.

How can I prevent that?

I want the hci always to be powered, so that the keyboard can reconnect
every time I hit a key.

As it is, whenever I want to use it, I have to ssh in from another
system, run bluetoothctl and therein run power on and connect $MAC.

You can imagine how frustrating that is.

The box has a Gigabyte F2A88XN-WIFI board, which came with a laptop-
style mini-pcie card with an intel 7260 802.11n on the pcie and an
8087:07dc bluetooth on the usb.

bluetoothctl show says:

it should not do that at all. Once a controller is powered that should stay until you tell it otherwise.

However what might happen is that the whole machine goes to sleep and the Bluetooth controllers gets kicked off the USB bus. That is something we can't do anything about. So check dmesg and look for USB disconnects.

You can also check with btmon what happens when the keyboard disconnects. If the controller goes away it will tell you as well.

Regards

Marcel

Since I wrote, I powerred it back on and is has remained up, but still
refuses to reconnect to the keyboard w/o an explicit connect command in
bluetoothctl.

I ran btmon until the keyboard disconnected; the last few events were:

Today I ran hcidump and hit a key on the keyboard; that showed:

As you can see, there are a couple of Connection refused - security
block errors.  Is there a permission issue which I miss?

For reference:

this looks like a recent kernel since it cleanly handles the page scan. However Page Scan enabled means that you are again connectable. So once the keyboard disconnects, the kernel will accept new connections.

So it is clearly that the actual connection attempt from the keyboard arrives and is allowed to continue by the lower layers. However when opening the L2CAP channels from the HID control and interrupt endpoints, it refuses to let you connect.

Can you check /sys/kernel/debug/bluetooth/hci0/link_keys that you indeed have the keys available.

However I have the fear that your keyboard is violating the Bluetooth spec. Please check /sys/kernel/debug/bluetooth/hci0/features or btmgmt info. I assume your local controller supports Secure Simple Pairing (every 2.1 or later controller does) and your keyboard does as well.

What this means is that the initiator device (in this case your keyboard) has to enable encryption. And BlueZ refuses the L2CAP connection if the ACL link is not encrypted (as mandated by the spec).

Can you run a hcitool info <bdaddr> against your keyboard and see who is the chip/module manufacturer on that keyboard.

The LegacyPairing: no is not a 100% indication, but I assume your keyboard is actually a Bluetooth 2.1 keyboard with Secure Simple Pairing.

Do you have an exact model number or link? We might have to buy one of these keyboards.

OK.  In retrospect, it is possible that I had suspended to ram before

OK.  So it seems that the keyboard is OK with encryption if the box

I got that one to support my trackpoint addiction. :^/

Are there any good tech specs for bt available w/o cost?

this is an unauthenticated link key from SSP. Surprising to me that you do not have an authenticated link key. That is odd.

Can you capture a pairing procedure with your keyboard with btmon? Then I can tell what is actually going on between these two devices.

The features page 1 should list at least 0x01 to indicate Secure Simple Pairing support. Can you run hciconfig hci0 features and btmgmt info to check this. Make sure the controller is powered on. The page 1 changes when powered on. If it does not reflect in debugfs, then we have a bug in debugfs.

That is the whole point behind Secure Simple Pairing. The initiator of the connection is responsible for encrypting the link. And the acceptor is required to reject the connection if the link is not encrypted.

So when BlueZ initiates the connection, we of course encrypt the link first. Seems the keyboard does not do that.

This is odd. It should show also features page 1. Run btmon while executing this command and I can tell you what is going on.

The Bluetooth specs are available for fee. Just go to bluetooth.org.

MH> The LegacyPairing: no is not a 100% indication, but I assume your
MH> keyboard is actually a Bluetooth 2.1 keyboard with Secure Simple
MH> Pairing.

MH> Do you have an exact model number or link? We might have to buy one
MH> of these keyboards.

>> I got that one to support my trackpoint addiction. :^/
>> 
>> Are there any good tech specs for bt available w/o cost?

MH> Can you capture a pairing procedure with your keyboard with btmon?
MH> Then I can tell what is actually going on between these two devices.

After unpairing, it refuses to re-pair at all.  So now no keyboard
whatsoever......

So the max_page value is 0, but it should be 1 for this controller. I think that is what is tripping up the command and not reading page 1. The page is clearly available as the other trace shows. And yes, the keyboard has Secure Simple Pairing enabled.

Most likely it has a button that you need to press or hold to make it forgot the current key.

And when in bluetoothctl, make sure you start an agent. That is the piece that will ask you for the passkey.

I got this keyboard now and the max_page value set to 0 is a clear bug with this keyboard. However, the kernel already works around this one. I did fix the command line userspace tools to include the same fix now.

So I did a basic pairing with this keyboard and it works as expected. It has SSP enabled and it does proper keyboard input handling for the passphrase.

What I am thinking is that you initially pairing with Legacy Pairing and then switched on SSP later on. This confused the keyboard and it things to allow Legacy Pairing. However that is really not how this works in the end.

When you make sure to remove all pairings and re-pair the keyboard it should all work fine and the keyboard should re-establish the encryption before trying to open HID control and interrupt channels.

Dear Experts,

Here is an emergent question about BlueZ feature:
I read the doc "supported-features.txt", which says BlueZ supports HID host=
.
And my question is whether HID device is supported?
Or can I use BlueZ HID profile to implement the Bluetooth HID device such a=
s a Bluetooth mouse or keyboard?

Thanks!

Gilbert

it should be pretty simple to implement a HID device role. There have been external projects in the past that did this. The reason why this is not in BlueZ is mainly due to the fact that we would need to get the input events from some kind of source. So if you have that figured out, then it should be simple to provided HID device role.

Hi,

I add KEYB to sdp:
#sdptool add KEYB

And HID service can be found and connected by a remote dongle on PC,
>From log, connect_event_cb() is called, but this function calls input_device_set_channel(), in which find_device() returns NULL, because the global variable "devices" is NULL, so the connection can not be established.
I want to know how to modify here for successful connection as a keyboard.

And I'm not very clear which interfaces should be called for HID device role to send data(such as a key press).

Sicerely expect your advice! Thank you!

First of all, no top posting in the mailing list please, second the
sdptool shall not be used since you did not have any plugin to
implement it won't work, in order for this to work input plugin
probably needs changes, it just happens to connect because the PSM are
the same for both roles but since there is no actual record for the
host the plugin will never be initialize to work with the device
connecting thus the error you are seeing.

We could in theory enable HID device record but then input needs to
handle incoming connections and interface with some event input that
you might have to register over D-Bus, if you don't really have an
input device to be used as a source you could use uinput to emulate
one then bluetoothd would have to listen to the events, translate (not
sure if this step is really needed though) them to HID and then send
to the remote.

Hi Luiz,

Thanks a lot!
Assuming we have the input source and BlueZ working as a HID device,
what interface BlueZ will expose for us to send a key press to remote? /dev/xxx or function call?
In another word, how to transfer the key press from input device to BlueZ?

Best Regards,
Gilbert

I guess you did not pay attention to the comment about top posting in the l=
ist:

http://www.bluez.org/development/lists/

Regarding the mechanism to hand over the events, as I said it already,
you probably need to come up with a proposal, something like
InputManager.Register("/dev/xxx") could work but I did not think about
the details and we could perhaps have the kernel doing some sort of
pass-through mode if the source input is already an HID device.
