HI,
I'm using Raspberry Pi 3 to send a android a value, picked up by a sensor, stored in a firebase database. What I'm looking to do is to get that value stored in a file, in the Pi and send it via bluetooth, to the android smart phone and from here the app is connected to wifi, will send this value to the database and perform a query.
The Pi is set up with a Listener to the phone and both can send and receive files fine to one another. The issue is, how to get the value from the Pi to the phone automatically and we will be starting this process using a cron to run the sensor script every maybe 10 seconds.
Really appreciate if anyone can help out.
Thanks
