I am having trouble connecting H743 wing to 915mhz radio. I’m not sure I have it wired properly to begin with. I am using UART 7 on the H743. I notice that my radio has no wires in the connector for cts and rts. This worked fine for APM2 with out any additional settings . I have tried setting the SERIALx_PROTOCOL to 1 for mavlink and no change.
Radio lights are solid green when powered.
