Command Structure¶

The common options of the call and dispatch commands are documented here. The specific command structure is shown below.

tinkerforge call air-quality-bricklet [<option>..] <uid> <function> [<argument>..]¶

Parameters:	<uid> – Type: String <function> – Type: String

The call command is used to call a function of the Air Quality Bricklet. It can take several options:

• --help shows help for the specific call command and exits
• --list-functions shows a list of known functions of the Air Quality Bricklet and exits

tinkerforge dispatch air-quality-bricklet [<option>..] <uid> <callback>¶

Parameters:	<uid> – Type: String <callback> – Type: String

The dispatch command is used to dispatch a callback of the Air Quality Bricklet. It can take several options:

• --help shows help for the specific dispatch command and exits
• --list-callbacks shows a list of known callbacks of the Air Quality Bricklet and exits

tinkerforge call air-quality-bricklet <uid> <function> [<option>..] [<argument>..]¶

Parameters:	<uid> – Type: String <function> – Type: String

The <function> to be called can take different options depending of its kind. All functions can take the following options:

• --help shows help for the specific function and exits

Getter functions can take the following options:

• --execute <command> shell command line to execute for each incoming response (see section about output formatting for details)

Setter functions can take the following options:

• --expect-response requests response and waits for it

The --expect-response option for setter functions allows to detect timeouts and other error conditions calls of setters as well. The device will then send a response for this purpose. If this option is not given for a setter function then no response is sent and errors are silently ignored, because they cannot be detected.

Parameters:	<uid> – Type: String <callback> – Type: String

The <callback> to be dispatched can take several options:

• --help shows help for the specific callback and exits
• --execute <command> shell command line to execute for each incoming response (see section about output formatting for details)

Basic Functions¶

tinkerforge call air-quality-bricklet <uid> get-all-values¶

Output:	iaq-index – Type: Int, Range: [0 to 500] iaq-index-accuracy – Type: Int, Range: See symbols temperature – Type: Int, Unit: 1/100 °C, Range: [-231 to 231 - 1] humidity – Type: Int, Unit: 1/100 %, Range: [-231 to 231 - 1] air-pressure – Type: Int, Unit: 1/100 hPa, Range: [-231 to 231 - 1]

Returns all values measured by the Air Quality Bricklet. The values are IAQ (Indoor Air Quality) Index (higher value means greater level of air pollution), IAQ Index Accuracy, Temperature, Humidity and Air Pressure.

The following symbols are available for this function:

For iaq-index-accuracy:

• accuracy-unreliable = 0
• accuracy-low = 1
• accuracy-medium = 2
• accuracy-high = 3

tinkerforge call air-quality-bricklet <uid> set-temperature-offset <offset>¶

Parameters:	<offset> – Type: Int, Unit: 1/100 °C, Range: [-231 to 231 - 1]
Output:	no output

Sets a temperature offset. A offset of 10 will decrease the measured temperature by 0.1 °C.

If you install this Bricklet into an enclosure and you want to measure the ambient temperature, you may have to decrease the measured temperature by some value to compensate for the error because of the heating inside of the enclosure.

We recommend that you leave the parts in the enclosure running for at least 24 hours such that a temperature equilibrium can be reached. After that you can measure the temperature directly outside of enclosure and set the difference as offset.

This temperature offset is used to calculate the relative humidity and IAQ index measurements. In case the Bricklet is installed in an enclosure, we recommend to measure and set the temperature offset to improve the accuracy of the measurements.

tinkerforge call air-quality-bricklet <uid> get-temperature-offset¶

Output:	offset – Type: Int, Unit: 1/100 °C, Range: [-231 to 231 - 1]

Returns the temperature offset as set by set-temperature-offset.

tinkerforge call air-quality-bricklet <uid> get-iaq-index¶

Output:	iaq-index – Type: Int, Range: [0 to 500] iaq-index-accuracy – Type: Int, Range: See symbols

Returns the IAQ index and accuracy. The higher the IAQ index, the greater the level of air pollution.

If you want to get the value periodically, it is recommended to use the iaq-index callback. You can set the callback configuration with set-iaq-index-callback-configuration.

The following symbols are available for this function:

For iaq-index-accuracy:

• accuracy-unreliable = 0
• accuracy-low = 1
• accuracy-medium = 2
• accuracy-high = 3

tinkerforge call air-quality-bricklet <uid> get-temperature¶

Output:	temperature – Type: Int, Unit: 1/100 °C, Range: [-231 to 231 - 1]

Returns temperature.

If you want to get the value periodically, it is recommended to use the temperature callback. You can set the callback configuration with set-temperature-callback-configuration.

tinkerforge call air-quality-bricklet <uid> get-humidity¶

Output:	humidity – Type: Int, Unit: 1/100 %, Range: [-231 to 231 - 1]

Returns relative humidity.

If you want to get the value periodically, it is recommended to use the humidity callback. You can set the callback configuration with set-humidity-callback-configuration.

tinkerforge call air-quality-bricklet <uid> get-air-pressure¶

Output:	air-pressure – Type: Int, Unit: 1/100 hPa, Range: [-231 to 231 - 1]

Returns air pressure.

If you want to get the value periodically, it is recommended to use the air-pressure callback. You can set the callback configuration with set-air-pressure-callback-configuration.

Advanced Functions¶

tinkerforge call air-quality-bricklet <uid> remove-calibration¶

Output:	no output

Deletes the calibration from flash. After you call this function, you need to power cycle the Air Quality Bricklet.

On the next power up the Bricklet will start a new calibration, as if it was started for the very first time.

The calibration is based on the data of the last four days, so it takes four days until a full calibration is re-established.

New in version 2.0.3 (Plugin).

tinkerforge call air-quality-bricklet <uid> set-background-calibration-duration <duration>¶

Parameters:	<duration> – Type: Int, Range: See symbols, Default: 1
Output:	no output

The Air Quality Bricklet uses an automatic background calibration mechanism to calculate the IAQ Index. This calibration mechanism considers a history of measured data. The duration of this history can be configured to either be 4 days or 28 days.

If you keep the Bricklet mostly at one place and it does not get moved around to different environments, we recommend that you use a duration of 28 days.

If you change the duration, the current calibration will be discarded and the calibration will start from beginning again. The configuration of the duration is saved in flash, so you should only have to call this function once in the lifetime of the Bricklet.

The Bricklet has to be power cycled after this function is called for a duration change to take effect.

Before firmware version 2.0.3 this was not configurable and the duration was 4 days.

The default value (since firmware version 2.0.3) is 28 days.

The following symbols are available for this function:

For <duration>:

• duration-4-days = 0
• duration-28-days = 1

New in version 2.0.3 (Plugin).

tinkerforge call air-quality-bricklet <uid> get-background-calibration-duration¶

Output:	duration – Type: Int, Range: See symbols, Default: 1

Returns the background calibration duration as set by set-background-calibration-duration.

The following symbols are available for this function:

For duration:

• duration-4-days = 0
• duration-28-days = 1

New in version 2.0.3 (Plugin).

tinkerforge call air-quality-bricklet <uid> get-spitfp-error-count¶

Output:	error-count-ack-checksum – Type: Int, Range: [0 to 232 - 1] error-count-message-checksum – Type: Int, Range: [0 to 232 - 1] error-count-frame – Type: Int, Range: [0 to 232 - 1] error-count-overflow – Type: Int, Range: [0 to 232 - 1]

Returns the error count for the communication between Brick and Bricklet.

The errors are divided into

• ACK checksum errors,
• message checksum errors,
• framing errors and
• overflow errors.

The errors counts are for errors that occur on the Bricklet side. All Bricks have a similar function that returns the errors on the Brick side.

tinkerforge call air-quality-bricklet <uid> set-status-led-config <config>¶

Parameters:	<config> – Type: Int, Range: See symbols, Default: 3
Output:	no output

Sets the status LED configuration. By default the LED shows communication traffic between Brick and Bricklet, it flickers once for every 10 received data packets.

You can also turn the LED permanently on/off or show a heartbeat.

If the Bricklet is in bootloader mode, the LED is will show heartbeat by default.

The following symbols are available for this function:

For <config>:

• status-led-config-off = 0
• status-led-config-on = 1
• status-led-config-show-heartbeat = 2
• status-led-config-show-status = 3

tinkerforge call air-quality-bricklet <uid> get-status-led-config¶

Output:	config – Type: Int, Range: See symbols, Default: 3

Returns the configuration as set by set-status-led-config

The following symbols are available for this function:

For config:

• status-led-config-off = 0
• status-led-config-on = 1
• status-led-config-show-heartbeat = 2
• status-led-config-show-status = 3

tinkerforge call air-quality-bricklet <uid> get-chip-temperature¶

Output:	temperature – Type: Int, Unit: 1 °C, Range: [-215 to 215 - 1]

Returns the temperature as measured inside the microcontroller. The value returned is not the ambient temperature!

The temperature is only proportional to the real temperature and it has bad accuracy. Practically it is only useful as an indicator for temperature changes.

tinkerforge call air-quality-bricklet <uid> reset¶

Output:	no output

Calling this function will reset the Bricklet. All configurations will be lost.

After a reset you have to create new device objects, calling functions on the existing ones will result in undefined behavior!

tinkerforge call air-quality-bricklet <uid> get-identity¶

Output:

uid – Type: String, Length: up to 8 connected-uid – Type: String, Length: up to 8 position – Type: Char, Range: [a to h, z] hardware-version – Type: Int Array, Length: 3 0: major – Type: Int, Range: [0 to 255] 1: minor – Type: Int, Range: [0 to 255] 2: revision – Type: Int, Range: [0 to 255] firmware-version – Type: Int Array, Length: 3 0: major – Type: Int, Range: [0 to 255] 1: minor – Type: Int, Range: [0 to 255] 2: revision – Type: Int, Range: [0 to 255] device-identifier – Type: Int, Range: [0 to 216 - 1]

'o'	Threshold is triggered when the value is outside the min and max values
'i'	Threshold is triggered when the value is inside or equal to the min and max values
'<'	Threshold is triggered when the value is smaller than the min value (max is ignored)
'>'	Threshold is triggered when the value is greater than the min value (max is ignored)

If the option is set to 'x' (threshold turned off) the callback is triggered with the fixed period.

The following symbols are available for this function:

For <option>:

• threshold-option-off = x
