L1 LED blinking on ROSbot 3 PRO

When starting my ROSbot, the L1 LED keeps blinking suspiciously (4 long blinks, 4 short blinks, repeatedly). It does not stop at any time: should I worry about this?

The system seems to boot normally: I can connect screen+keyboard to it, or ssh to it. I recently did apt-get update / apt-get dist-upgrade to see if that led to improvement, the blinking remains as it was. Also, I just fully charged the batteries: same result.

Can you move the robot? If the flashing frequency is around 1/2 Hz, it may indicate a firmware problem. Either the board is stuck, or a memory leak has caused something to go wrong.
I suggest performing:

  • power reset
  • rosbot.flash or ./flash_firmware.sh

The default state of LED L1 is no light when there is no communication (rosbot driver is turned off) or it lights up constantly (when communication has been established)

I ran the flash script and L1 is back to normal. Thanks!
