rtw88 VS bluez

Not a high end device (Dell Vostro 15 3515), but it comes with preinstalled Ubuntu as well. It has some serious problems with wireless (10ec:c821). The default driver frequently loses connection on some wifi networks (it has issue with many networks though surprisingly not all of them). Sometimes reloading the driver helps, sometimes it just hangs my system. https://github.com/lwfinger/rtw88 seems to work a bit better though still has the same problem sometimes. It turns out that rfkill block wlan && sleep 3 && rfkill unblock wlan works better than reloading the driver. At least this way I haven't hanged my system yet. And wifi does not seem to be able to work at the same time as bluetooth.

Otherwise a fine device.

this is one i recognize from other support threads: https://github.com/lwfinger/rtw88

So my laptop has the RTL8821ce WIFI adapter, which doesn't like to work with the Linux OS. I've tried both the official rtw88 driver, and the unofficial rtl8821ce-dkms-git drivers, and although they work, they are less than ideal to say the least. (Connection drops randomly, range is abysmal, and net speed is painful)

I have installed Larry Finger’s rtw_8723de wifi driver for my chip rtl8723de. I have to blacklist it from loading at boot as the system does not boot if I don’t blacklist it. Is there a way to figure what goes wrong?

I have the same wifi adapter. Unfortunately, it does not work out of the box in linux. You need to install this exact driver for it work properly. Instructions for ubuntu are written there. And obviously you are going to need an internet connection first. I use an ethernet cable for this, but if you lack that, you may be able to download the necessary packages through windows, move them to linux storage and do an offline install there but I don't know the specifics of that procedure.

- On Linux: post suspend/sleep got the the same error like: https://github.com/lwfinger/rtw88/issues/56 - I tried to disable `aspm` and/or `msi` and the workaround mentioned in the issue, but it does not work.

I've tried to install these drivers: https://github.com/lwfinger/rtw88, but it still doesn't work.

Maybe this https://github.com/lwfinger/rtw88 works.

The driver for that card is rtw88. It should be included in the kernel or in this github repo. Since you're on Manjaro it's probably in the AUR as well.

5.68 with the fix is out: https://github.com/bluez/bluez/releases/tag/5.68

These are some links I checked and followed: https://github.com/bluez/bluez/blob/master/test/simple-agent https://scribles.net/creating-ble-gatt-server-uart-service-on-raspberry-pi/

The only issue I have is that I can't use LDAC with my bluetooth headphones (Sony WF-1000XM4). This is probably related to bluez: https://github.com/bluez/bluez/issues/313 It's fixed in bluez 5.65 which is not available in the repositories (yet). The current repository version of bluez is 5.64.

I am sorry but this is still not clear enough. I will assume that you are using a Linux based system e.g a raspberry pi and a Xbox one series x/s controller (the one with the share button). If this is the case, I have bad news for you: they still didn’t fix the problem with the Bluetooth ble inside the Bluetooth stack implementation on most Linuxes OS (Debian, Ubuntu or anything that uses BLUEZ). If the controller is not the latest BLE version, it is only a matter of updating it to a newer kernel (5.13 or higher) and the latest blues version, as there was also another problem that was solved for the older controllers. If you are in the first case where they didn’t fixed it yet. You can report it on GitHub or just follow this issue https://github.com/bluez/bluez/issues/155 to check if something new comes up, there is also the possibility to use a Bluetooth dongle and somehow “transplant” the pairing keys from a windows computer to Linux so that the controller leaves this “connection loop”.
