bluetooth disconnect after pairing

[dermurxer]

Hello everyone,

I have an IoT2050 Siemens microcontroller running Debian 11.9 with Kernel 5.10.104-cip3. Recently, I added an Intel AX200 network card via an adapter (mPCIe>M.2) and now I'm trying to connect my smartphone to the microcontroller via Bluetooth. The goal is to transmit data arrays between the smartphone and the microcontroller using TCP or UDP.
However, I'm facing an issue where the Bluetooth connection disconnects after pairing (see screenshot). I've already attempted to follow a guide (https://www.howtoforge.com/bluetooth_pand_debian_etch ), but it doesn't seem to work with my kernel.

I believe the problem has a simple solution, but I haven't been able to figure it out.

Thank you for your suggestions!

Best regards

Hello,

I have an IoT2050 Siemens microcontroller running Debian 11.9 with Kernel 5.10.104-cip3. Recently, I added an Intel AX200 network card via an adapter (mPCIe>M.2) and now I'm trying to connect my smartphone to the microcontroller via Bluetooth.

According to the log in the previous message, it looks like you are connecting the controller to your smartphone (named "Xperia 5 IV"). Your phone may be refusing to connect. Check smartphone configuration.

Some questions/requests:

• I assume your controller is using a customised Debian version: can you report the link to the controller's manual?

• Please report your general hardware/software configuration with the command:

  Code: Select all

  inxi -Fz

• Have you installed the Intel firmware for the new Intel AX200 network (mPCIe>M.2) ?

• Can you analyse/report for warning/errors/useful messages from your system log? You can use the following command after trying to connect via Bluetooth:

  Code: Select all

  script log.txt
  su -l -c "journalctl -b --no-pager"
  exit
  

  You can report logs in one the following ways:
  • paste them into the Debian Pastezone service (https://paste.debian.net) and report the URL/link of the paste in a follow-up message
  • attaching the logs to a follow-up forum message as a compressed zip or gz file
  • paste logs into the body of a follow-up message between code tags (if they fit the size of a forum message)

• Please reports screen output of microcontroller's as text (instead of as image), if possibile

Hope this helps.

note: if I understand correctly, you are trying to configure a TCP/IP over Bluetooth connection between the controller and a smartphone; this will probably require a separate topic if you want to delve into it.
