# 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. Monitor power button and trigger clean shutdown
#   2. Launch sdlamp2 as the main process
#
# Install: copy to /mnt/vendor/bin/rg35xx-wrapper.sh
# Config:  set CMD in dmenu_ln to point here instead of sdlamp2 directly

# --- WiFi hotspot ---
# Deprioritized: connecting the device as a WiFi client to a shared network
# works fine even when sdlamp2 replaces the stock menu. Hotspot/AP mode isn't
# needed — SSH access works over the shared network.

# --- Power button monitor ---
# axp2202-pek on /dev/input/event0 sends KEY_POWER (code 116).
# logind has HandlePowerKey=ignore, so we handle it here.
