Cannot set to IR displaymode for XT709 of EVO II v1, and where I can find the firmware version of the drone rather each component?

[lbdhr]

Hi, I am holding an Autel EVO II v1.0 drone with the XT709 camera. I am now developing the Android APP based on the Android Mobile SDK.

When I ran the setDisplayMode function in the camera widget to set the camera to the IR display mode, I just got an error showing "The command failed." while other settings like setExposure can be performed normally.

In addition, I also cannot find the version number of the firmware from the AUTEL Explore APP. I can see many version numbers of "flight control (V0.0.4.85)", "camera (V0.2.33.16)", "remote control (2.0.4.12)" and so on. None of them has a relationship with the "Supported Product List and Firmware Version: V2.7.35" referred to in the README file. I have downloaded the latest firmware of V2.7.4 and installed it through the SD card. But nothing changed.

Could you please help me solve these problems? Thank you!
