(I'm answeirng for Joem since he's out for a long weekend) The following is the `calib_data`, as received during initialization. I verified over two reboots that the data was consistent: ``` 000005.468,I,BMP388,get_calib_data results: 00 DD 6A 51 49 F6 C9 00 1E F6 23 00 55 61 CA 77 F3 F6 A3 3F 16 ``` Is this the right data? The code used to print the above data is copied below:   ``` static int8_t get_calib_data ( struct bmp3_dev *dev) { int8_t rslt ; uint8_t reg_addr = BMP3_CALIB_DATA_ADDR ; /* Array to store calibration data */ uint8_t calib_data[ BMP3_CALIB_DATA_LEN ] = { 0 } ; /* Read the calibration data from the sensor */ rslt = bmp3_get_regs(reg_addr , calib_data , BMP3_CALIB_DATA_LEN , dev) ; LOG_C_INFO ( "BMP388" , "get_calib_data results: " ) ; for ( int idx = 0 ; idx < BMP3_CALIB_DATA_LEN ; idx++) { LOG_C_INFO_BASIC ( "%02X " , ( unsigned int ) calib_data[idx]) ; } LOG_C_INFO_BASIC ( " \n " ) ; /* Parse calibration data and store it in device structure */ parse_calib_data(calib_data , dev) ; return rslt ; } ```     ...
