SOLVED = Temasek CM11 Rom + Note3 sm-n9005 + Garmin GSC 10 ANT+
so just to let you know,
i had already installed ANT+ Radio Service, ANT+ Plugin Manager, ANT+ Plugin Sampler. IpBike, IpBike SensorMan.
Which still did not work.
I then found ANT+ Enabler in the play market. The app says its only compatible with the Nexus and HTC.
So i mailed the developer and her said the sm-n9005 has the same chipset as the Nexus so it should work.
It has. I didnt even need a reboot. Started IpBike SensorMan, started the service, searched for sensors, spun the wheel on my bike [using the Garmin GSC 10 Speed/Cadence Sensor] and within a second it was detected. After that i assigned the sensor to the Bike profile in IpBike. Done.
ANT+ Enabler did cost me 10USD but worth it I guess.
Note though Edmundo still will not detect that my phone has ANT+ Hardware. But I'll be using IpBike to upload data to Strava.
