Button Functions

The functionality of the buttons can differ depending on the specific LoRa APRS tracker device you are using. This page outlines the button operations for the most common devices.

T-Beam

The T-Beam tracker has three buttons. The functions are consistent across all versions.

• Left Button (near the USB port): This is the power button, managed by the internal AXP power management unit.

  • Press and hold for approximately 8 seconds to turn the device on or off.

• Middle Button: This is the user button.

  • A double press will enter or exit the on-screen menu.
  • A short press will force the tracker to send a beacon immediately (provided a GPS fix is available).
  • If you are using the display timeout feature, a short press will also wake up the screen.

• Right Button: This is the reset button.

  • A short press will restart the device.

The Heltec Wireless Tracker is equipped with two buttons. When holding the tracker with the USB port facing down, the buttons operate as follows:

  • A short press will force the tracker to send a beacon or wake up the screen if it has timed out.
  • A double press will enter or exit the on-screen menu.
  • A long press (about 2 seconds) will turn the device off by putting it into a deep sleep mode.
