Bluetooth pairing is not working well (RTL8852CE)

[ruei_chang]

Hi there,

I’d like to ask for help.I’m experiencing a Bluetooth pairing issue. I have two smartphones, a Sony Xperia 1 VI and a Samsung S23+, also have three Bluetooth speakers that are ready for pairing.

However, only my Sony Xperia 1 VI and one of the Bluetooth speakers can connect to the Orin Nano. The other devices are unable to connect properly. Currently, I’m using a custom board with a my builded L4T OS(JP 6.2).

My vendor asked me to check it on devkit to see if the issue is still existed. I’ve tested with the devkit, flashing both JetPack 6.2 and JetPack 6.1 via SDK Manager, but the problem remains.

Here is my defconfig from builded OS, not from SDKManager
defconfig.txt (262.7 KB)

I found there are three topics with bluetooth question. I have tested those methods below, but the issue is still there.

Can't receive file via Bluetooth on Jetson AGX Orin with JetPack 6

Hi DaneLLL, I have tested the default RTL8822CE with AGX Orin developer kit, it has the same problem with RTL8852BE’s Bluetooth issue. It can send file to other devices, but cannot receive file from another device. Please check it again. Below are some informations about RTL8822CE module.

Can't connect my orin nano to another device in bluetooth

Hi, I tried to install the package from your link and I have the same behavior. I also tried to connect with a bluetooth headset using the jetson (also tried using bluetoothctl and my lapatop to compare and i can connect using connect command). From a jetson terminal, all the command to connect to the bluetooth headset with bluetoothctl (connect, trust, pair) provide the following error message: Device HEADSET_ADDRESS not available I connect to the jetson in ssh so I can’t realize the GUI p…

Hi, Please try this: Ubuntu 18.04 unable send or receive files via bluetooth Please launch Bluetooth Manager on TX2/Ubuntu 18.04. And the window should pop up. We have tried it on 4.6.4(r32.7.4) and it works fine.

Also had followed the instruction for Bluetooth Audio

Hi,
Please share the steps. We don’t have the two phones but can try with our Android phones.

Hi,

[Smartphone paring]
I found a solution to fix the connection between Samsung and Bluetooth(tegra-ubuntu).

I installed blueman. And when I tried to connect to the Samsung phone it will show up a dialog to confirm bluetooth pin. After clicked confirm button, then the connection between Samsung and Bluetooth can be established.

However, I got my Sony Xperia 1 VI a wired action. I click my Xperia device from Bluetooth list. The notification showed connected message. But as you see, the status in the list is still in pairing.

I waited for a few seconds, it was still in pairing until the connection is broken.

And I tried to use my Sony Xperia 1 VI to connect to the tegra-ubuntu. The tegra-ubuntu showed up a dialog to confirm bluetooth pin like Samsung phone.

The connection will be established after the Bluetooth PIN is confirmed.

Another issue of Bluetooth speaker, the speaker is still unable to pair with tegra-ubuntu successfully…the connection never be established successfully…

Hello,

I think I fixed the problem…

I found a website which has a guideline to setup the bluetooth of jetson orin.

I installed libghlib2.0-dev libdbus-1-dev libdbus-c++ -dev libudev-dev libical-dev libreadline-dev.

And use the Bluetooth Manager to pair and trust the device. Then Everything is great. The devices, which cannot be connected before, can be connected and play a music to it.

But I still don’t understand why I can’t pair and connect to the Bluetooth device from Setting. I can only pair and connect to the Bluetooth device properly with Bluetooth Manager.

Hello,

I tested the devkit using its default Bluetooth module, not the RTL8852CE. The results were the same as with the RTL8852CE: only one of my three Bluetooth speakers could connect to the devkit. The other two still couldn’t…I don’t think it’s an issue of module.

Do you verify the Bluetooth’ interoperability and compatibility on Orin Nano?

Hi,
It looks to be an issue in Ubuntu OS. The default system does not handle the condition so additional package is required. Should be missing some handling in userspace and kernel driver is fine.
