example_wirelessHandle not working on A1

[Shifters1]

I own a Unitree A1 robot running version 3.3.1. While other examples work perfectly, the "example_wirelessHandle" doesn't respond when I press key A or any key, despite being in Low-Level. Interestingly, the robot's remote control Bluetooth functions well with the robot when I'm not running this specific example. No errors are displayed when I run the example; the keys just don't work.

Could someone assist with a solution? Am I missing anything?
