Response:

  • >RXATI{ID1},{TAG1},{VALUE1};{ID2},{TAG2},{VALUE2};...< — List of sensors with values
  • >RXATIU< — No temperature sensors connected

Response Fields

FieldFormatDescription
ID14-hex charsSensor ID (DS18B20)
TAGSingle letter (A–J, or U if untagged)Sensor tag (assigned via XATL)
VALUESign + 4 digitsTemperature value (e.g., +0250 = 25.0°C, -0100 = -10.0°C)

Examples

Query connected sensors:

>QXATI<
>RXATI28000013406C1001,A,+0250;28000013406C1002,B,+0180<

This response shows:

  • Sensor tagged A (ID 28000013406C1001): 25.0°C
  • Sensor tagged B (ID 28000013406C1002): 18.0°C

No sensors connected:

>RXATIU<

Temperature Value Format

The value is a 4-digit number representing temperature in tenths of degrees Celsius:

ValueTemperature
025025.0°C
1850185.0°C
00000.0°C
-010-1.0°C (note: negative sign included)

Notes

  • Sensors must be tagged with XATL to appear in the list
  • Temperature values are read in real-time from connected sensors
  • Query this command periodically to monitor sensor data
  • Tags are A–J (maximum 10 sensors)
