Add Indicator LED for Status & Support for Addressable LEDs

[Witty-Wizard]

Feature Description
Currently, there is no clear visual indication of the system’s status, which makes debugging and monitoring less intuitive. Adding an indicator LED will provide immediate feedback on system states (e.g., power, connection status, errors). Additionally, support for addressable LEDs would be great

Good idea. Need this func~

This would be a major improvement, especially for trouble shooting purposes.
Let's start with the builtin onboard LED of the XIAO-C6.

I do not see how a single LED could indicate all the possible problems that might be present. What would be a useful indication?

Hi Wolfgang,
My suggestion: Make it configurable by user.

• flash or blink for "received packets" like a FTDI in Arduino
• blink for "transmitted packets"
• blink on "MavLink hearth beat" (optional, not every body transmits MavLink)

In the past I have used a modified version of ESP-Now-Serial-Bridge. It's a transparent link only. Here the LED behavior was user's choice. Maybe it's an inspiration...

Another option is an addressable LED. Have used the "ESP-Now-Serial-Bridge" on "M5Stamp-pico" boards.

That's what exactly I had in mind with a ws2812 led driver.

Another possible way to use a single LED to show different conditions is the LED behavior of ExpressLRS.

I do have 90 Multicolor LED strip. i've tried dual way chasing and Rainbow type colors, but they're kinda blocking the main system, or on the other hand, the main system is blocking the led strips controlling. Well, for current situation, i'm falling back to fixing colors for ARMED, LAND, LOITER, etc.

I would also like status LED support. I may suggest two LEDs like indicators on wired network cards. One LED for connection status (like disconnected/connecting/connected) and second LED for data activity, like short blink per packet
