I'm building a BLE application, main functionality is real-time data polling from the sensor board.
This board has an open sourced lib: https://github.com/zentri/ble_commander_ios
In order to get the data, you need to keep sending command to the sensor board as soon as you receive the data come back from the sensor.
Now I have several view controller all conform to this delegate and getting data back seperately.
But I'm trying to integrate this data polling function to a single class. within this class, I need to conform to that delegate, keep sending command to sensor.
Question: How can I make this "readdata" delegate method always running in background no matter which view controller I'm in.
Thanks
