SOFTWARE DEVELOPMENT KITS
We provide Software Development Kits by way of iOS and Android source code can be found in Blue Maestro’s Github to assist in the development of custom iOS or Android applications. The iOS and Android source code are examples based on Blue Maestro’s own apps available on the App Store and Google Play. They enable you to develop your own applications to scan for Bluetooth® Low Energy “advertisement” packets from our sensors and data loggers parsing them for their telemetric data, the extraction of logged information by forming a temporary connection with the sensors and the implementation of Blue Maestro’s innovative UART command line interface providing unparalleled flexibility in changing the settings of our Bluetooth® Low Energy sensors and data loggers from any iOS or Android smartphone.
Tempo Disc™ Bluetooth® Low Energy sensors and loggers do not require internet connectivity to work. However, should internet connectivity be required, Blue Maestro provides a simple and cost effective internet gateway called Tempo Anywhere™ that will be stream Tempo Disc™ Bluetooth sensor and data logger to Blue Maestro Cloud™ for storage and remote monitoring. Tempo Anywhere™ works by connecting via Wi-Fi to an available internet Wi-Fi router.
FREQUENTLY ASKED QUESTIONS
Q. How does Tempo Disc work?
A. Tempo Disc works by taking sensor readings at fixed intervals, advertising those readings and other key data in real time and then storing the readings for later extraction. The default for sensor readings is once every 10 seconds and for logging the default is once very 1 hour. These are user configurable.
Q. How many smartphones can communicate with a Tempo Disc at the same time?
A. Technically there is no limit to the number of smartphones that read data from a Tempo Disc at the same time. This is a key benefit of Tempo Disc since many smartphones can read data from it without having to form a connection to it. The saves time, makes Tempo Disc good for use cases where there are many users and preserves battery life. When it comes to extracting the log, only one smartphone can do it at a time. However it is very quick, approximately 1000 records every few seconds.
Q. How many Tempo Discs can I read from one smartphone?
A. It is technically unlimited. When it comes to downloading the logged data, only one smartphone can do it at a time, but it is quick.
Q. How many days of logging can I get?
A. This depends on the logging interval you set. For example, at the default of one hour 4,000 / 24 = 166 days. At 10 minutes it is 4,000 / 24 / 6 = 27 days. At once every 4 hours it is approximately 2 years.
Q. What happens to the log data once I extract it from Tempo Disc to my smartphone?
A. The log remains in the Tempo Disc, but is now available to analyse on your smartphone
Q. What is the battery life?
A. Depending on a number of factors, it is approximately 1 year. The battery life can be extended by changing the configuration to advertise less quickl. The battery is a CR2032 coin cell and is easily changed. You will see the battery level in the apps.
Q. What is the range?
A. The range is about 75 meters/ 220 feet line of sight. It is reduced where there are obstructions and it depends on the type of material of the obstruction.
