BlueZ D-Bus Thermometer API description
Santiago Carot-Nemesio <>
Health Thermometer Manager hierarchy
Service org.bluez
Interface org.bluez.ThermometerManager1
Object path [variable prefix]/{hci0,hci1,...}
Methods RegisterWatcher(object agent)
Registers a watcher to monitor scanned measurements.
This agent will be notified about final temperature
Possible Errors: org.bluez.Error.InvalidArguments
UnregisterWatcher(object agent)
Unregisters a watcher.
EnableIntermediateMeasurement(object agent)
Enables intermediate measurement notifications
for this agent. Intermediate measurements will
be enabled only for thermometers which support it.
Possible Errors: org.bluez.Error.InvalidArguments
DisableIntermediateMeasurement(object agent)
Disables intermediate measurement notifications
for this agent. It will disable notifications in
thermometers when the last agent removes the
watcher for intermediate measurements.
Possible Errors: org.bluez.Error.InvalidArguments
Health Thermometer Profile hierarchy
Service org.bluez
Interface org.bluez.Thermometer1
Object path [variable prefix]/{hci0,hci1,...}/dev_XX_XX_XX_XX_XX_XX
Properties boolean Intermediate [readonly]
True if the thermometer supports intermediate
measurement notifications.
uint16 Interval (optional) [readwrite]
The Measurement Interval defines the time (in
seconds) between measurements. This interval is
not related to the intermediate measurements and
must be defined into a valid range. Setting it
to zero means that no periodic measurements will
be taken.
uint16 Maximum (optional) [readonly]
Defines the maximum value allowed for the interval
between periodic measurements.
uint16 Minimum (optional) [readonly]
Defines the minimum value allowed for the interval
between periodic measurements.
Health Thermometer Watcher hierarchy
Service unique name
Interface org.bluez.ThermometerWatcher1
Object path freely definable
Methods void MeasurementReceived(dict measurement)
This callback gets called when a measurement has been
scanned in the thermometer.
int16 Exponent:
int32 Mantissa:
Exponent and Mantissa values as
extracted from float value defined by
Measurement value is calculated as
(Mantissa) * (10^Exponent)
For special cases Exponent is
set to 0 and Mantissa is set to
one of following values:
+(2^23 - 1) NaN (invalid or
missing data)
-(2^23) NRes
+(2^23 - 2) +Infinity
-(2^23 - 2) -Infinity
string Unit:
Possible values: "celsius" or
uint64 Time (optional):
Time of measurement, if
supported by device.
Expressed in seconds since epoch.
string Type (optional):
Only present if measurement type
is known.
Possible values: "armpit", "body",
"ear", "finger", "intestines",
"mouth", "rectum", "toe",
string Measurement:
Possible values: "final" or
