Please also check when you press the MD button, does the green LED turn ON?

I have went through the process here to set the baudrate and parity as you have shown and can get it working. I am thinking maybe this is related to the firmware inside the BP sensor. Please double check your frimware version; it should be 1.06 or later. You can check it by checking register 121:

If it is not, please follow the instructions from this page and see if the problem gets resolved.

Hello,

The commands look correct. If you refer to the documentation for the BP sensors, you will note that these two registers has the property of R/Wp. This means that it is write-protected. You will need to hold down the MD button on the BP sensor when you issue the commands for it to work.
