Can variable transports by bluetooth?

Hi

I have making wearable device used nano, MAX30100

I made heart beat code and SpO2

I want those variable transport Android mobile phone

As I surfed Internet, written bluetooth comm can sensor value

but sensor value is not equal variable, is it?

So, I want know variable transportation with bluetooth

if it is possible, Can you introduce example code?? or way?

Sensor values are normally stored in a variable upon reading.

Heaps of examples out there on bluetooth/Arduino/Android. Use Google.
