The problem was described here: https://forums.fedoraforum.org/showthread.php?318910-Driver-for-realtek-RTL8723BS-wifi-bluetooth-chip dmesg: http://vps2.happyuser.info/lynx7-problem/dmesg.txt

Some check:

$ dmesg | grep ttyS
[    1.677076] 00:02: ttyS0 at I/O 0x3f8 (irq = 27, base_baud = 115200) is a 16550A
[    1.703273] 80860F0A:00: ttyS4 at MMIO 0x50d47000 (irq = 17, base_baud = 2764800) is a 16550A
[    1.703558] serial serial0: tty port ttyS4 registered
[    1.716888] 80860F0A:01: ttyS5 at MMIO 0x50d4d000 (irq = 18, base_baud = 2764800) is a 16550A

$ ls /dev/ttyS4
ls: cannot access '/dev/ttyS4': No such file or directory

Why I see the ttyS4 in dmesg but the /dev/ttyS4 file does not exist?

Seems like duplicate of issue #28, but with ttyS4 not ttyS1. And, seems like this repository is kinda inactive since 2016.

Hi, I have made progress, commented in #28 It looks like they are trying to make the latest kernels work with the Realtek sdio bluetooth drivers but it is hacky....the WiFi on these fairly new Chuwi tablets is only 2.4GHz which is surprising. Incidentally, the WiFi signal, after upgrading the kernel, seems to be a lot stronger. Since it is a combined Bluetooth/WiFi chip, likely related to the progress they made.
