Bluetooth Connection Issue with RTL8822CE on Jetson Orin NX Super Running JetPack 6.2

[429894465]

On the Jetson Orin NX Super with JetPack 6.2, using an RTL8822CE Wi-Fi card, I found that when trying to connect to Bluetooth headphones, some devices fail to connect, while a few specific headphones can connect successfully. I’m not sure where the issue originates.

After switching to JetPack 5.1.5, the Bluetooth connection problem does not occur. However, I would prefer to use JetPack 6.2 because of its superior performance for Jetson Orin NX, so I cannot revert to the older version.

Could you advise what might be causing this issue and how to resolve it?

The carrier board is as follows:

Please try with the patch at Can’t receive file via Bluetooth on Jetson AGX Orin with JetPack 6 - Jetson & Embedded Systems / Jetson AGX Orin - NVIDIA Developer Forums to see if can help.

Thanks

Hello. The problem on my end is not that I need to use Bluetooth to receive files, but that I need to connect Bluetooth earphones, which is a problem of not being able to connect

The following is my log of finding that the connection cannot be established. It looks like Jetson initiated a pairing request, but it timed out or was rejected by the earphones during the “bonding” phase. I was wondering why the headphones refused him?

Hi,
Please apply this setting and try again:

I have tried this method before, and just now I tried it again, but it did not work. I am wondering if it is a problem with the Bluetooth driver?

“# CONFIG_BT_LE is not set” BLE (Bluetooth Low Energy) mode was not enabled during kernel compilation.
Could this possibly affect me

Hi,
If it’s specific to certain devices, it’s very likely some kernel configs are missing. You may enable the configs for a try. And also suggest check whether there’s error in dmesg.
