How to bypass backgroundFetch restrictions when sending data in the background?

Question

iOS

It is necessary to transfer data from the iOS application to the server while the application is in the background. The data is small amounts of data about the status of the user's device (related to iBeacon technology and the user's location). Data must be sent every half an hour / hour. At the same time, the application itself can be in background mode for quite a long time (several days), which causes a problem with backgroundFetch restrictions.
Are there any solutions to this problem?

Answer 1

Send pushes to devices - they will wake up and it will take about 30 seconds to send data
