Board Connection Timeout

in Android
Hi Eric,

I encountered an issue that after a long period of execution, my application cannot connect to a specific sensor since all the connection attempts were timed out. I then try to connect with Metawear application, normally it takes 30~80 seconds to connect, but sometimes it will not show the fragment until I click 'Cancel', which is really weird. After I disconnected from the sensor, the connection in my app worked.

I don't know whether it's related to the timeout settings. If it is, I wonder if we can configure the board connection timeout ourselves? I looked into the source code, the timeout is set to 15 seconds in the API.

Thanks!

    There is no way to configure the timeout in the current API.  15 seconds should be sufficient time to establish a connection with the board.  If it takes 30+ seconds, something is not right with your device or OS.

    What Android OS and device are you testing with?

    I'm testing with LG Optimus Fuel. The Android system is 4.4.

    The only thing I can think of is a Bluetooth error Samsung phones were having due to Samsung's Android OS variant:

    Do you have another Android device to test with?  If not, you should look into acquiring more devices and testing on various Android OSes.
