Hello,

I am having issues connecting my GalaxyRVR to the Controller App. I’ve followed the instructions and uploaded the provided code onto the R3 Board while the switch is in Upload mode. After that I then moved it back and reseted the board.

This is what the serial monitor outputs:

```auto
GalaxyRVR version 1.1.0
Initialzing...
SET+RESET
...ets Jul 29 2019 12:21:46

[Init]
[OK] 1.4.0
[OK]
ESP32 firmware version 1.4.0
checkFirmwareVersion: 1.4.0
SET+NAMEGalaxyRVR
...[OK]
[OK]
SET+TYPEGalaxyRVR
...[OK]
[OK]
SET+APSSIDGalaxyRVR
...[ERROR] SET+ Unknown command
SET+APSSIDGalaxyRVR
...[ERROR] SET+ Unknown command
SET+APSSIDGalaxyRVR
...[ERROR] SET+ Unknown command
[FAIL]

```

Thanks in advance!

EDIT: Here is a photo of the rover. (Maybe it helps?)

Revert to previous code release. Seems to be a new issue with latest release.

> I just solved this. I had to to install an older “Sunfounder AI Camera” library version, then it worked. I can now also use the STA or AP mode, no errors on the console. Version 1.0.6 of the library worked for me, version 1.1.0 does not work for me.

Thank you so much for the help. It works now.
