Does Xert mobile support the Cyclops Hammer in Erg mode? I have been trying to get it to work and so far no joy. The Hammer does not show Xert mobil as connecting via ANT+ (or bluetooth) but I was able to see power being reported. There was no Erg functionality. I am using a Samsung Android phone and the remote player. I am seeing wattage being reported in the remote player as well but it is quite glitchy.
It should work perfectly in ANT mode. Be sure to start the activity to see power and get trainer control.
