I swapped out my Bosch SPH for a Nyon (thanks @retiredNH for your advice on this) on a Trek Allant 8s. I recently picked up a new iPhone and it doesnt fit in the SPH or its universal phone case. Plus I was never the biggest fan of that system anyway, so I decided to jump to the Nyon as I plan on keeping this bike for 3-5 more years. For the most part, everything is fine. Ive upgraded to V3 and my favorite feature is the customizable screens to be able to show exactly what I want to see. I am having one issue...Im using the Heartcast app to broadcast my Apple Watch heartrate to the Nyon. My phone (which I believe is required for the connection) goes in a small saddle bag so it's always nearby. I noticed that the bluetooth connection randomly drops out, and Im currious to know if anyone else has this problem with either Heartcast or HRMs in general?
