sdlamp2 now catches SIGTERM and SIGINT via a sig_atomic_t flag checked in the main loop, ensuring position and volume are saved before exit. Previously, a kill signal would terminate instantly without saving. New tools/rg35xx-wrapper.sh replaces sdlamp2 as the dmenu_ln CMD on the RG35XX Plus. Skeleton includes placeholders for WiFi hotspot and power button monitoring (TBD after on-device investigation). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

# RG35XX Plus wrapper for sdlamp2
|
|
#
|
|
# Launched by dmenu_ln instead of sdlamp2 directly. Handles device-specific
|
|
# concerns that don't belong in the player binary:
|
|
# 1. Start WiFi hotspot (AP mode for SSH access)
|
|
# 2. Launch sdlamp2 as the foreground process
|
|
# 3. Monitor power button and trigger clean shutdown
|
|
#
|
|
# Install: copy to /mnt/vendor/bin/rg35xx-wrapper.sh
|
|
# Config: set CMD in dmenu_ln to point here instead of sdlamp2 directly
