The device performs a software reset.
Normal startup logic follows (200ms
delay until data starts streaming).

3.4. Sensor payload
This mode provides users with measured distances displayed in the form of binary
messages using 5 bytes:
TXXSCRC8
.
The Payload will contain 3 bytes of data (2 for
distance in mm
, 1 status byte), and 2
metadata bytes (header and checksum).
Status byte: Two bits to indicate overtemperature (>50°C) and critical temperature
(>60°C) , three bits to indicate the status of distance measurement and three bits to
indicate the quality factor of the distance measurement.
The checksum byte is calculated out of the first 4 bytes of the message (header byte,
distance reading bytes, and status code byte)
Header (1 byte)
:
T (84 decimal / 0x54 hex)
Distance reading in mm (2 bytes) :
XX (MSB, LSB)
Status Code Byte (1 Byte)
:
S (One byte to indicate code status of distance
measurement. See the Status Codes section below)
.
Checksum (1 byte)
:
CRC8
Byte 1

3.5. Status codes
Certain status codes will be detected and reported by the firmware using the 4th byte of
the payload. Each bit in the byte represents a status flag as described below.
