did you solve your problem? i have the same issue here, it change some packs, but looks like when it change baud rate it can't keep the communication...
In source code i can't find your baudrate code "14c05202", in truth there are two tables for baudrate in the code of hciattach_rtk.c, one there are not in use and another that is used. More weird is that there are some place that both values are used, in the function "uart_speed_to_rtk_speed" the initial value is using the code 0x701D that be part of the table that are not in use.
I had try to disable the change speed of baudrate but i got a new error...

Best regards,
Igor

Hi!

I solved my issue removing the config file.
sudo rm /lib/firmware/rtl_bt/rtlbt_config

then it works for me, even getting some errors at the startup.

Now i have it working with 1500000 of baudrate.
