Please note the SimplePack 2.0 is a legacy device and is not available anymore.
API 5 firmware is used by the SimplePack 2.0 and SimplePack 1.1 devices and covers a myriad of use cases through seven user modes that use the button and also the accelerometer.
For more data on how to parse API 5, please have a look at the
Heartbeat - A heartbeat message is sent if no other message has been sent for a specified period of time (specified in time interval since any message sent)
Departure delay - Time between pressing the button and arming the system
Automatic arm - In API 5. Starts from last movement disarm. Is non-linear
Accelerometer sensitivity - Movement detection sensitivity.
Sleep time - Time in minutes after alarm/stop message is sent when the device does not send any more messages (ignoring any movements to save battery and Sigfox subscription message count). This value is non linear in API 5.
Arrival delay - Time in minutes after which if device doesn't move a message is sent. (Track me / Trace me mode / Put me back / Don’t drop me) or in Trace me mode period when the device does not stop the Tracing (non linear in API 5)
Tracing interval - Time in minutes how often a message (notification) is sent while the device moves.
Downlink period - Applicable for Monitor me (Maintain me) mode. Downlink is requested after specified number of uplink messages.
Vibration measurement window - Applicable for Monitor me mode. Value 1 to 255 represents repetitions of acceleration measurement (when making decision if there is vibration or not). Smaller value increases risk of ignoring vibration. Higher value increases current consumption of the device (longer detection time).
Arm by:
Pressing the button
Downlink forced by extra long press or forced by heartbeat
After specified time of movement inactivity (API5)
Disarm by:
Automatic downlink after alarm or heartbeat
Automatic disarm
Long press (if active)
LED lights while the button is pressed (blinks quickly).
LED lights while the radio is transmitting (blinks slowly).
LED is lit for 40 secs while waiting for downlink.
LED blinks 20 times fast to acknowledges successful downlink.
No LED indication if downlink is not successful.
LED blinks (1 per 1 sec.) while in departure delay.
LED blinks (1 per 3 sec.) while in sleep time.
All LED lights can be switched off by downlink with the exception of press indication.
To force downlink request, do an Extra-long press of 10 seconds.
The device LED will blink quickly while the button is pressed and after 10 seconds, it will start to blink slowly for the duration of message transmission. The LED will be lit uninterruptedly for 40 seconds while the device waits for downlink. If the downlink is successful, the device will blink quickly 20 times to acknowledge this.
Battery voltage and MCU temperature is reported in all heartbeats.
Battery voltage and MCU temperature can be appended to all payloads (with exception of Monitor me).
Voltage during transmission is reported (VDD tx)
All of the use cases use the accelerometer with the exception of Press me, where the button is used. All can be further configurated with the settings above.
Report single click, double click or long press (3 - 6 secs.).
No arming or disarming.
Recommended downlink (payload: 01 18 00 00 00 00 00 00):
Estimated battery life:
More than 4000 clicks.
Arm by pressing the button, arming can be reported.
Any movement is reported.
Accelerometer sensitivity can be adjusted.
In case of repeated movement alert triggers, a time frame can be set between alerts (so no message is sent).
Recommended downlink (payload: 02 18 1E 07 4A 00 00 00):
Estimated battery life:
More than 4000 messages.
Imagine a luggage. You don't care about position while it's moving, but want to know when the movement starts and when it stops (to know e.g. which airport it ended up at).
After departure delay (arming) detection starts.
If the object doesn't move for Arrival delay, Stop notification is sent and downlink can be requested.
The device stops reacting for the duration of the Sleep time interval.
If the device starts to move again, an Alarm is sent and the device starts detecting stillness again.
Recommended downlink (payload: 03 18 1E 07 01 0A 00 00):
Estimated battery life:
More than 4000 messages.
Imagine a parcel/package. You want to trace the approximate position and time while it's moving using Sigfox geolocation service. It sends periodic messages while in move.
If object moves, a message is sent periodically set by the Tracing interval.
If the object stops to move for Arrival delay Stop notification is sent and downlink can be requested.
The device stops reacting for the Sleep time interval.
If the device starts to move again an Alarm is sent and the device starts detecting movement again.
Recommended downlink (payload: 04 18 1E 07 41 4A 0A 00):
Estimated battery life:
More than 4000 messages.
Measures any vibration within predefined time slots and sends the message after 11 slots are filled in. Suitable to monitor running hours of any bridge, engine, car.
A movement is detected each second (can be increased in API 5) . Each detected movement increases the counter from 0 to 255, e.g. number 200 means that the movement was detected in 200 samplings from 255, or in another words, the vibrations were detected in 78% (= 200/255) of 4 min 15 seconds interval (=255 seconds in default setup).
There are 11 counters (bytes) in every message, so the message contains 11 numbers, representing 2805 (=255x11) measurements.
If at least one movement is detected within the 2805 sampling interval (default is 2805 secs which equals 46 minutes), the whole record with 11 counters is sent within one message.
If no movement detected, nothing is sent.
Sensitivity can be adjusted.
The time window in API5 is flowing so the first sample is always a movement.
Recommended downlink (payload: 05 18 1E 07 DC 14 00 00):
Estimated battery life:
More than 4000 messages.
Imagine anything leaning or turning or displaced.
The mode measures min and max positions of the accelerometer while moving.
When movement stops (device is steady for defined time), a message is sent with current orientation data.
Garbage bins, road signs, electricity poles... Possibilities are endless.
If a movement is detected, a measurement starts.
Sensitivity can be adjusted.
The measurement continues until stillness for a time period set in Arrival delay is achieved.
A message with min, max and final values of device orientation related to ground (Earth gravity) is sent and downlink can be requested.
The device stops reacting for Sleep time interval. -
If another movement is detected, a measurement starts again.
Recommended downlink (payload: 06 18 1E 07 4A 01 00 00):
Estimated battery life:
More than 4000 messages.
Monitors and measures any major impact during transportation.
If major acceleration is detected (throwing, banging, falling), alarm is sent.
Sensitivity is adjustable.
The device stops reacting for Sleep time interval.
If major acceleration is detected again, another alarm is sent.
Recommended downlink (payload: 07 18 1E 07 41 00 00 00):
Estimated battery life:
More than 4000 messages. The permanent sensing of the accelerometer takes some energy.
