    Hi Matthew! You should try the following steps:

    1. Delete any app on any device you use CABLE with
    2. Restart the device(s)
    3. Redownload the apps & connect

    I am also suffering the same issue.

    I have removed all apps and re-installed but Cable is still flashing red at 1.5-2 secs.

    New firmware update has caused this to happen and I can no longer train indoors - is there the ability to factory reset etc?

    App ver 1.3.2
    Cannot get app to provide HW or FW version.

    Cannot get cable to turn on. No lights, blinking or otherwise. All batteries new on all devices: Garmin speed, cadence, hrm, Powertap power meter. When speed sensor is spun; green light blinks on speed but cable does not see.
    iPhone 12 Pro ver 15.6. Firmware for cable was updated.
    No other apps open.

    Cannot get to work to capture Ant + and out put to Bluetooth on phone.

    Any help? Revert firmware? It all worked fine for years with a double tap…
