Using real-time data from Android app?

Hi everyone, first post in the forum.

I was wondering if there is a somewhat straightforward way to get and use realtime data from a phone app. More specifically I am looking into how to get some values of geomagnetic activity from this app into TD.

Any leads would be much appreciated!

i used bluetooth serial once … there are some android aps that send sensor data over bt serial. With a blueetotth dongle … you can use usb serial … you just need to select the port , baudrate … and lane ending sometimes …
LE i think you can serial send over the cable as well . just search the android apps for sensor serial
