My Pebble flashes on and off when charging
This can occur when the battery is completely drained.
The watch tries to boot, which disables charging, and a loop occurs.
- While connected to the charging cable, press and hold any button on the watch, until an error code appears on the screen.
- Release the button. Now, let the watch charge for some time (at least an hour).
- Finally, press a button to exit the error code.
