There are 2 ways to collect and export data from Bluetooth Beacon Tracker.
Real-time data
If you need real-time data you can think about developing a solution based on the Synchronous API. You need to create a script that makes calls to the Synchronous API every 5 seconds and stores (inside a log file or a database) the list of BLE beacons detected (identified by the MAC addresses).
Frequency of the calls to the API
It is not useful to call the API, more than once every 5 seconds. Why? Because the locations of the BLE beacons detected and returned by our API do not change within those 5 seconds windows. So, making calls with an higher frequency would be only a waste of resource on your side and on our side. The BLE nodes scan the environment for traffic and send data to our Indoor Tracking server every 5 seconds and we can not change this parameter.
Historical data
If you do not need real-time data, we have a service that does all the work for you. Please take a look at this page.
