982440d21d Noise floor (#9347)
* add noise floor

* Sliding window noise floor

* Add getCurrentRSSI() to SimRadio for noise floor support

* Remove sendLocalStatsToPhone call from runOnce

* Change noise floor to int32_t type

* Use int32_t for RSSI sample storage in noise floor

* Remove float cast from noise floor assignment

* Fix Copilot review issues: fix noise floor logic, types, and null pointer

- Use robust busyTx/busyRx checks instead of simple isReceiving check
- Initialize noiseFloorSamples to NOISE_FLOOR_MIN instead of 0
- Move noise_floor assignment inside null check to prevent potential crash
- Change getNoiseFloor() and getAverageNoiseFloor() to return int32_t
- Fix RSSI validation to check for positive values (rssi > 0)
- Fix format specifier from %.1f to %d for int32_t
- Update comments to accurately reflect the sampling logic

* Fix RSSI condition to include zero value

* Change noise floor initialization to zero

* Disable noise floor for LR11x0 chips: getRSSI(bool) unsupported

* Remove updateNoiseFloor call from onNotify to avoid radio queue overflow

Per PR review feedback, calling updateNoiseFloor() in onNotify() for every
ISR event (ISR_TX, ISR_RX, TRANSMIT_DELAY_COMPLETED) can cause the LoRa
radio queue to get full. The noise floor sampling still happens in
startReceive() and after transmitting.

* fix lr11x0 current rssi

* Address noise floor review comments

* Address Copilot SimRadio noise floor comments

* Fix RadioLibInterface formatting

Overview

This repository contains the official device firmware for Meshtastic, an open-source LoRa mesh networking project designed for long-range, low-power communication without relying on internet or cellular infrastructure. The firmware supports various hardware platforms, including ESP32, nRF52, RP2040/RP2350, and Linux-based devices.

Meshtastic enables text messaging, location sharing, and telemetry over a decentralized mesh network, making it ideal for outdoor adventures, emergency preparedness, and remote operations.
