I encountered issue, when sensor is connected but not displaying data, it’s been with the android phone, the other phone works just fine. But as far as I know it’s common issue when trying to connect sensor to multiple devices. Strangely the only sensor that could work with both phones was a speed sensor. The only panacea was to reset the Bluetooth settings and having only one device with active Bluetooth. If not, the problem will repeat. Any suggestions are welcome.
