* 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 --------- Co-authored-by: Ben Meadors <benmmeadors@gmail.com> Co-authored-by: Jonathan Bennett <jbennett@incomsystems.biz>
