I have been using the RWGPS app for android and like it a lot.
everything was going good till I installed a Topeak PanoBike Bluetooth Smart Cadence and Speed Sensor
after the sync of the new Bluetooth device my GPS speed is no longer displayed when I ride. When the ride is finished i can look and see that the speed was recorded
I am NOT using the speed sensor in the Topeak PanoBike Bluetooth Smart Cadence and Speed Sensor I am only using it for cadence in fact the magnet for the speed sensor is not even on the bike at all.
