X96Max+_2101 Bluetooth Not recognized

[salsabilng]

Hi! Thank you for your hard work, nice! I'm just wondering, can i enable the RTL8822CS bluetooth? the wifi works, but the bluetooth seems not working properly. The Bluetooth only loaded when i use modprobe bluetooth then i can see the loaded bluetooth log in kernel log.

I checked that bluetooth has been added in dtb.

This driver comes from a third party and is not included with the mainline kernel.

It is very rare that you can use wireless, and many people report that wireless cannot be used.

Is the wired network of this box Gigabit or 100M? I see that your u-boot does not correspond to the installation option, did you manually change the u-boot?

[salsabilng]

no, i done nothing. my box is gigabyte with JL2101, im only following the instructions. yes the wlan is on, i can connect but it sometimes disconnect. (not stable). well, looks like indeed RTL8822CS is not good after all, i will use bluetooth dongle anyway. thanks for your help
