Can anyone tell me whether I'm using correct commands for calculating the temp and pressure for the sensor "MS5837-30BA"?

Basically I’m using “MS5837-30BA” (https://bluerobotics.com/store/sensors-sonars-cameras/sensors/bar30-sensor-r1/) this sensor. While debugging I observed the following values,
Temp = 106.76(varies)
Pre = 1021

I’m gerrting incorrect temp data. I just want to know whether I’m using correct commands or not?

Also is there C Library available for this sensor if yes then please let me know.

#define reset_cmd 0x1E

#define BLRBTCS_PR_SENSE 0x00 //DEVICE ROUTINE SELECTION ID FOR PRESSURE SENSOR.

#define RESET 0x02

Any libraries would be found on their Github. Blue Robotics · GitHub

Sorry but, I haven’t found any library available for the C.

Then there is no library directly from BlueRobotics. What are you using to read the data?

Here is some c++ code from our Arduino library where the temperature and pressure are calculated. The calculations were pulled directly from the datasheet. If you need help with your own code, you need to post the entire code.
