Does Cadence Support Gear Data or Screen Changes with SRAM eTap AXS or Shimano Di2?
Cadence only supports Bluetooth sensor data (not ANT+), and unfortunately neither SRAM eTap AXS or Shimano Di2 sends gear data or allows shifter buttons to switch screens over Bluetooth.
In fact, Shimano Di2 doesn’t send that data over standard ANT+, but their own proprietary Private ANT protocol.
As soon as either system supports Bluetooth, Cadence will add support for showing what gear you’re in and allowing buttons to swipe between screens.
