Cannot Find SERIAL6 Parameter in Mission Planner and see nothing in serial ports

[Esther_Le]

Hi everyone,

I’m new here and would really appreciate some help.

My setup:

• Mission Planner version: 1.3.82
• Flight Controller: MatekF765-WSE
• Firmware: ArduCopter_with_BL 4.6.1

I was trying to configure a serial port for my flight controller in Mission Planner. I’ve connected a telemetry radio (LR24F) to UART6, and I expected to see SERIAL6_* parameters in the Full Parameter List. However, they’re missing — I can see other serial ports (e.g. SERIAL0 to SERIAL5), but not SERIAL6.

I’ve attached a screenshot showing what I mean.
I was told all serial ports should be configured via the Full Parameter List, but I can’t find SERIAL6 at all.

Has anyone encountered this before? Any advice would be much appreciated!

Thanks in advance!

Default UART order

• SERIAL0 = console = USB
• SERIAL1 = Telemetry1 = UART7 (support CTS and RTS signaling)
• SERIAL2 = Telemetry2 = USART1
• SERIAL3 = GPS1 = USART2
• SERIAL4 = GPS2 = USART3
• SERIAL5 = USER = UART8
• SERIAL7 = USER = UART6 (TX only unless BRD_ALT_CONFIG = 1, then RX available also)
• SERIAL8 = USER = UART5 (RX only, for ESC telemetry)
