Error when network up/down #7

Closed theBASTI0N closed 3 years ago

theBASTI0N commented 3 years ago

On occasion when the network goes up and down an error is happening where ble discovery is stopped. Happens if WAN is disconnected/reconnected or if WiFi goes down/up.

When using bletool listen a message "Removed by server" appears.

I am using version 3.4.5 on a x750.

To simulate this:

  1. bletool enable
  2. bletool discovery
  3. bletool listen
  4. disconnect and reconnect wan cable. Repeat this until error message is seen.

When using HTOP bledaemon is reloaded when this error occurs.

Cannot build 3.4.6 to test.

Thank you for your feedback. I will test this as soon as possible.

If the connection is based on WiFi when down the error will happen multiple times a minutes.

This is probably because the output of the kernel is not completely masked.The connection between X750 and Bluetooth module multiplexes the system output serial port. I have informed my colleagues in the routing group to follow up on this issue.

@theBASTI0N Please type "echo 1 4 1 7 > /proc/sys/kernel/printk" in the SSH background and and see if the issue occurs again. Also confirm that you are currently with the latest x750 firmware version(v3.201).

Hey thanks for the update.

I am running v3.201.

After running the command I still see the error.

Still looks like network up/down's are causing the bledaemon to restart which causes this issue to remain.

The bletool listen process continues to run even when a restart of bledaemon happens, with Removed by server being the last message printed.

The issue is not the output of bletool listen but bledaemon restarting.

This doesn't seem normal.You can turn off bledaemon in the background(type "/etc/init.d/bledaemon stop"), run bledaemon in the foreground(type "bledamon"), and see what log output comes out

If you connect your gateway to phone hotspot it is easiest way to test.

I ran the above suggested and in another terminal bletool listen. I get this from bledaemon: big endian

When I turned off my phone AP i get this printed out from bledaemon:

Segmentation fault

I have pushed the new code, please test whether the issue has been successfully fixed.
