Pressure Mode

The host sends command (0xB0) to DSPC01 and the module will return 3 bytes of Hex data

representing pressure value (300hpa ~1100hpa) which should be transferred to decimal value.

Compass Mode

The host sends command (0xC0) to DSPC01 and the module will return two bytes of

unsigned data (0~359). In order to get the accurate direction, the compass should be calibrated

for the first use. After sending command (0Xe0) users should rotate the DSPC01 module

horizontally for at least 2 times and each circle should last at least 3 seconds. The DSPC01

module will quit the calibration mode after 10 seconds.

Temperature Mode

The host sends command (0x80) to DSPC01 and the module will return 2 bytes of Hex data.

The MSB of first byte is symbol bit so the temperature might be negative. The remaining 15
