2432S024 (R) GUITION: No GPS

Describe the bug If I wire ATGM336H (RX -> IO22 / TX -> IO21), GPS features never appear.

To Reproduce Steps to reproduce the behavior:

1. Wire ATGM336H: RX -> IO22 / TX -> IO21 / VCC -> 5v / GND -> GND
2. Power on CYD and wait for boot-up process to finish.
3. Make sure GPS has a lock (LED feedback from ATGM336H confirms lock).

Expected behavior GPS tools and GPS header logo present.

Screenshots If applicable, add screenshots to help explain your problem.

Marauder (please complete the following information if applicable):

• Firmware version: 1.15.1
• Hardware version: RL Phantom (Installed via ESPTerminator)
• CYD Source: https://a.aliexpress.com/_msYkmn1

Additional context Could not install ESP32 Marauder on device via MacOS, this is why I installed via espterminator.

I rebooted firmware after satellite lock confirmed 3 times—with no luck. Also retried the process with RX -> IO21 / TX -> IO22—with no luck.

Used grove ports to wire ATGM336H to CYD. Specifically the bottom 2 pins of this grove port:
