This is the support thread for the "STEPS EMTB Data" data field, found here on the app store: apps.garmin.com/.../461743f9-b350-486f-bd87-613c7b0bab90
It's a simple data field that connects via Bluetooth LE to your Shimano STEPS e-bike and displays useful information like battery percentage and assist mode.
Any problems or feedback, let me know!
