The file transfer speed on MacBook Pro 16,1 from an Android device to Mac is too slow even if I transfer a file of a few Kbs. In case of a transfer from Mac to my Android device, it simply fails.
Some logs that might be helpful :-

When it fails to set baud rate, btmon has the following:
< HCI Command: Broadcom Update UART Baud Rate (0x3f|0x0018) plen 6
Encoded baud rate: Not used (0x0000)
Explicit baud rate: 3000000 Mbps
> HCI Event: Command Complete (0x0e) plen 4
Broadcom Update UART Baud Rate (0x3f|0x0018) ncmd 1
Status: Command Disallowed (0x0c)
Not sure if this means the command is unsupported by this chip, or if an "Encoded
baud rate" needs to be specified.

Some additional errors are being seen in 5.16

I think that I remember that the to be used baud rate is inside ACPI and that the Broadcom chip inside the MacBooks don’t support baud rate change and just start out at the appropriate rate in the first place. Then again, I don’t have a MacBook running Linux and thus can verify this.
Actually I would start by dumping the ACPI tables and see if the resources for the UART are listed correctly.
