8 years ago I have no clue. There is one report of similar problems. It is possible that the baud rate is not 115200, but something higher. There has been one report that once the firmware is loaded, the rate jumps to a much higher rate. See https://github.com/lwfinger/rtl8723bs_bt/issues/7, but there is no solution there.

8 years ago with this command: sudo ./rtk_hciattach -n -s 115200 /dev/ttyS4 rtk_h4 i get the following answer:

8 years ago hi Walrabe : Have you solved this problem? I meet the same problem as you.
Hallo Larry,
i have a new MeeGoPad T02 and installed Ubuntu 15.10 on the internal eMMC. Then i downloaded/compiled/installed your rtl8723bs-master driver, all works fine (thanks for your work on it). After that, i downloaded/compiled/installed the _bt driver. Neither sudo ./rtk_hciattach -n -s 115200 /dev/ttyS4 rtk_h5 nor sudo ./rtk_hciattach -n -s 115200 /dev/ttyS5 rtk_h5 work for the MeeGoPad. I see ttyS4/ttyS5 in the dmesg and i modprobed rfkill-gpio manually, nothing works until now. Do you have any ideas? Thanks for your time!
Cheers, Chris Walrabe
