I recently received my Zymkey4i and I followed the documentation for installing it on our RPi3 running Raspbian (stretch). It’s running with a 2.5A power supply.
When the power is applied, the zymkey blinks rapidly (I’ll guess 5 times/sec)…then stops for 2 seconds…then blinks 5 times/sec for a second then switches to blinking 3 times/sec (for 10 blinks)…pauses for about a second…starts back up at 5 times/sec…pauses…3 times/sec (for 10 blinks)…pauses…and finally continuously blinks at 5 times/sec thereafter non-stop.
Is it supposed to blink 3 times/sec all the time after it’s bound to the device? Or is this normal operation?
