MFile extension with an app that already uses the BLE extension

MIT App Inventor Help

Has anyone had success using the MFILE extension with the BLE extension?

2

I just get a white screen if I try to use the MFILE extension with an app that already uses the BLE extension.

Companion version, device name, Android version?

4

Have you tried using your extension in combination with BLE?

5

Again...
