doLightSleep() skips a light sleep when the LoRa IRQ line is already asserted, and bounds that to LORA_IRQ_SKIP_SLEEP_MAX consecutive skips so a line stuck high cannot stop the node sleeping for good. But the counter was reset on the sleep it finally allowed, so the bound never stuck: a genuinely stuck-high line produced five skips, one sleep, five skips, one sleep, for as long as it stayed high. Each of those skipped attempts is not free. It runs waitEnterSleep() and the full notifyLightSleep / notifyLightSleepEnd observer pass, which detaches, arms and restores every wake pin - the path #12100 and #12131's interrupt storm live on - so the loop costs far more than the sleep it is protecting. Reset the counter only when the line is actually read low, which is the condition that says the radio is clearing its IRQs again. Nothing changes for the transient case the skip exists for: the line goes low as soon as the main loop services the packet, and the next sleep clears the count.

Meshtastic Firmware
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.
