If you're seeing this screen, your Bad Elf GPS Pro+ (BE-GPS-2300) firmware has been updated to version 3.0.0 or newer, but you need to update the firmware in the GNSS chipset as well.
This one-time update restores GLONASS functionality to your Pro+ and fixes the Year 2003 bug that appeared on 29-OCT-2022.
To upgrade your GNSS engine, follow the instructions below:
Instructions for updating the GNSS engine firmware:
- On your PC or Mac, download this file: MTK-2300.bin
- With your Pro+ powered OFF, connect the Pro+ to your PC/Mac using a standard mini USB cable.
- When prompted via the LCD screen, tap the bottom button to enter USB DRIVE MODE.
- The drive will appear in Windows File Explorer or Mac OS X Finder.
- Copy the MTK-2300.bin file onto this drive, and then eject the drive from File Explorer or Finder. Do not disconnect the USB cable.
- The LCD will indicate the Pro+ is SCANNING DRIVE FOR UPDATES, at which point it will detect the new firmware file and begin the update process. This will take about 2 minutes to complete.
- Once updated, you'll be prompted to tap the power button.
- This update is only required for the Pro+ (with gray enclosure), not for any other Bad Elf GPS receivers.
- This update cannot be performed over Bluetooth; you must use a PC or Mac.
- If you get a "FILE CORRUPTED" error, just try again starting from Step 2.
- If you continue to get the "FILE CORRUPTED" error, you may need to reformat the drive on your Pro+. Contact us via email@example.com and we'll walk you thru this process.
