What are the advantages/disadvantages of using Bluetooth or ANT+ sensors (speed, cadence, heart) with Wahoo Fitness iPhone case?
Is one system better or worse than the other for:
- battery drain
- other issues
I intend to use external battery charge battery so the phone has a constnt charge. I will charge the external battery with a hub dynamo. This will be on a tadpole trike to do long distance touring and randonneuring.
