TRAXXAS VXL8s calibration issue

Hello everyone,

For the past week, I’ve been trying to get a rover setup working with an MK15 radio, a V5+, and a Traxxas VXL8s ESC. When I turn on the ESC, it flashes green, which means it’s not interpreting the signal…
I tried arming it directly, setting the servo trim to 1504 and 1520, but nothing happened. Whether the ESC is in normal or bidirectional mode, there is no change, and when I try to calibrate the ESC, my minimum value is not recognized during calibration.
Does anyone have a similar setup or have encountered this kind of problem? After these tests and my various searches, I’m out of ideas.

Thanks in advance.
