LE pair disconnected


Tommy Lin (林志聰) <Tommy.Lin@...>
 

Hi Ryan Erickson,

We use zephyr source code(samples/bluetooth/hci_uart) , and type following commands:

After then , we can find out device(named “2019bt”) in our phone , and we can pair it.

But “2019bt” will be disconnected after about two second at connected.

Could you give us some suggestions

Thank  You.

Hi Zephyr team,

 

We can find this issue on nRF51 DK and our custom board with zephyr source code(samples/bluetooth/hci_uart). Could you give us your advice on how to solve this issue?

Hi Tommy,

 

Sorry, I am not able to try out your usecase on Bluez, as it has been quite sometime that I have been using with Bluez, due to my priorities, you may have to wait or ask someone else on the maillist to investigate the reasons for the host to disconnect the link.

I am suspecting that you are not running at client that subscribes to a service, and hence the lost host decides to disconnect the idle link.

 

Regards,

Vinayak

Hi,

The Linux kernel has a 2 second timeout for any connection that doesn’t have users. “Users” in this context are e.g. any user space sockets that use the connection. Normally when bluetoothd is running it owns the ATT socket, so there’s always at least one user. It sounds to me like Tommy might not have bluetoothd or any other GATT server running. Anyway, this is starting to be a bit off-topic for the Zephyr mailing list.

Hi Tommy,

Sorry, I am not able to try out your usecase on Bluez, as it has been quite sometime that I have been using with Bluez, due to my priorities, you may have to wait or ask someone else on the maillist to investigate the reasons for the host to disconnect the link.
I am suspecting that you are not running at client that subscribes to a service, and hence the lost host decides to disconnect the idle link.

Regards,
Vinayak

Hi Vinayak,
sorry to bother you again.
In your experience , what reason will cause “CONNECTION TERMINATED BY LOCAL HOST”



HCI Event: Disconnect Complete (0x05) plen 4
Status: Success (0x00)
Reason: Connection Terminated By Local Host (0x16)
@ MGMT Event: Device Disconnected (0x000c) plen 8
LE Address: 7A:03:05:31:E7:E6 (Resolvable)
Reason: Connection terminated by local host (0x02)

Hi Zephyr team,

We can find this issue on nRF51 DK and our custom board with zephyr source code(samples/bluetooth/hci_uart). Could you give us your advice on how to solve this issue?

Hi Ryan Erickson,
We use zephyr source code(samples/bluetooth/hci_uart) , and type following commands:
After then , we can find out device(named “2019bt”) in our phone , and we can pair it.
But “2019bt” will be disconnected after about two second at connected.
Could you give us some suggestions

Hi Johan,

Thanks for your information

 

I do following things:

1.     add Bluetooth.service file to /lib/systemd/system/bluetooth.service

2.     add bluetooth.conf file to /etc/dbus-1/system.d

 

and start Bluetooth service , but it is still auto disconnection after connection.

 

Could you continue to give us some suggestions

 

Thank You,

Tommy

Hi,

 

The Linux kernel has a 2 second timeout for any connection that doesnt have users. Users in this context are e.g. any user space sockets that use the connection. Normally when bluetoothd is running it owns the ATT socket, so theres always at least one user. It sounds to me like Tommy might not have bluetoothd or any other GATT server running. Anyway, this is starting to be a bit off-topic for the Zephyr mailing list.

Hi Tommy,
I wanted to circle back around to make sure you were able to get your questions answered. If not, please let me know and I will help get you the answers you need. 

If you have not done so already, you can join our Slack channel where most of the developers and maintainers are available. It is a great place to ask questions and talk to the community.
Best,
Thea Aldrich

Hi Johan,

Thanks for your information

 

I do following things:

1.     add Bluetooth.service file to /lib/systemd/system/bluetooth.service

2.     add bluetooth.conf file to /etc/dbus-1/system.d

 

and start Bluetooth service , but it is still auto disconnection after connection.

 

Could you continue to give us some suggestions

 

Thank You,

Tommy

Hi,

 

The Linux kernel has a 2 second timeout for any connection that doesnt have users. Users in this context are e.g. any user space sockets that use the connection. Normally when bluetoothd is running it owns the ATT socket, so theres always at least one user. It sounds to me like Tommy might not have bluetoothd or any other GATT server running. Anyway, this is starting to be a bit off-topic for the Zephyr mailing list.
