Specified by:

startScanningImpl in class NMEAGPSSpotter

stopScanningImpl

protected void stopScanningImpl()

Description copied from class: NMEAGPSSpotter

Stop collecting sentences from the gps device

Specified by:

stopScanningImpl in class NMEAGPSSpotter

scanningThreadRun

protected void scanningThreadRun()

cleanup

protected void cleanup()

findGPS

protected abstract void findGPS()

Locates a bluetooth gps device and hooks up serviceUrl, conn, and is. If no bluetooth gps device can be found, leave those 3 alone. Feel free to block in here if you like.
