Data field is a 4-byte return angle value, which is a compressed BCD code, S is the sign bit (0 positive, 1
negative) XXX is a three-digit integer value, and YYYY is a decimal value. The other axis data is the same. For
example, 10268010 means -26.801 degrees.

The data field is 12 Bytes, divided into four groups, namely x-axis angle, y-axis angle, temperature, and
battery power. Each group of angle 4 bytes is the compressed BCD code, the first bit is the sign bit (0 positive, 1
negative), three integer values, four decimal places; the temperature 3 bytes is the compressed BCD code, the
first bit is the sign bit (0 positive, 1 Negative), three-digit integer value, two decimal places; battery power is one
byte.
