Hi good day,

Thank you for reaching out to us regarding the issue you are experiencing with your Jumper. I understand how frustrating it can be when the system does not function as expected.

Let’s try a few troubleshooting steps to resolve this issue:

  1. Check Firmware Version: Ensure that both your transmitter and the ExpressLRS module are running compatible firmware versions. Sometimes, mismatched versions can cause loading issues.

  2. Reinstall Lua Scripts: Try deleting the current Lua scripts from your transmitter and reinstalling them. Make sure you are using the latest version of the scripts compatible with your firmware.

  3. SD Card Check: Verify that your SD card is properly formatted and has enough space. Sometimes, a corrupted SD card can cause loading issues. Reformatting the card and reloading the necessary files might help. This is a very common issue so just check all is formatted accordingly and that the SD is not corrupt.

  4. Factory Reset: If the above steps do not resolve the issue, consider performing a factory reset on your transmitter. Please ensure you back up any important data before proceeding with this step.

  5. Consult the Manual: Refer to the user manual for any specific instructions related to Lua scripts and ExpressLRS setup.

If you have tried these steps and the issue persists, please let me know.

How would you rate our customer service?

David

Any chance I could just have the transmitter sent back for repair or replacement I am super busy at the moment and that would be more convenient for me.

The Problem

The loading screen gets stuck because the ExpressLRS configuration script cannot find an ELRS module to communicate with.

Solution Steps

1. Access Model Settings

  • Open your model list
  • Navigate to page 2 of the settings

2. Configure RF Module

  • Locate the RF module settings
  • You will see two options:
    • Internal RF Module
    • External RF Module

3. Enable CRSF Protocol

  • If using internal module:
    • Select the Internal RF Module
    • Press ENTER
    • Change the protocol to CRSF (Crossfire)
  • If using external module:
    • Follow the same steps but select External RF Module instead

4. Test the Script

  • Return to the system menu
  • Try running the ExpressLRS LUA script again
  • It should now load properly instead of getting stuck

The root cause of this issue is typically having both RF modules turned off, which prevents the LUA script from finding a module to communicate with.
