Troubleshooting

Status LEDs​

The RAK Hotspot V2 includes two (2) small LEDs for status:


Figure 8456: Status LED location

🔴 Red LED: A solid red light indicates that the Pi is receiving power, which is normal during operation. If the red LED is flashing, it indicates a power supply issue. Reconnect the power and check again to resolve the problem.

🟢 Green LED: Upon power-up, the green LED will blink randomly for a brief period, typically about 5 seconds, before stopping. If the green LED continues to blink repeatedly for an extended period, it suggests a problem, usually related to the SD card, but possibly also due to a power issue.

In case the green LED continues blinking persistently, consider the following recommendations:

  1. Unplug the USB-C power cable.
  2. Remove the microSD card, check its position, and re-insert it ensuring it is properly seated. The card may have shifted during shipping or you might have inserted it incorrectly, perhaps upside down, after backing up.
  3. Reconnect the USB-C power cable, ensuring it is securely plugged in all the way.
