FOBO tire pressure monitoring system report..

[GoldOxide_imp]

I don't know the underlying implementation, however, each wireless message transaction costs the device some battery capacity. The more frequent, the more energy consumed. Device listening (if applicable) is not so expensive in terms of power, but when it sends out data, your button battery (s) take a hit.

During connection establishment between the phone and the device, there is an exchange of information. I am assuming the link is probably not encrypted (i.e. nothing secret about tire pressure), so device power consumption should be minimal.

Maybe the FOBO communication is just one way? Would you happen to know if you can configure anything inside the FOBO from within your phone app? Would you know if the devices are Bluetooth enabled?
