Context
The original Termux boot script (Hack #52) used sleep 15 to wait for WiFi before starting the gateway. This works most of the time — WiFi typically connects in 10-15 seconds. But on cold boot after a crash, WiFi can take 30-45 seconds. On those occasions, the gateway starts without network and fails to connect to API providers, entering a broken state.
The fix is a retry loop that actively checks for connectivity before proceeding, with graceful degradation if WiFi never comes up.
Implementation
Replace the fixed sleep with an active ping-based retry loop:
#!/data/data/com.termux/files/usr/bin/bash
# start-pocketclaw.sh — robust boot with WiFi retry
LOG="$PREFIX/tmp/pocketclaw-boot.log"
log() { echo "$(date '+%H:%M:%S') $1" >> "$LOG"; }
log "Boot sequence started"
# Acquire wake lock
termux-wake-lock 2>/dev/null
log "Wake lock acquired"
# WiFi retry loop — 12 attempts x 5s = 60s max
RETRIES=12
WIFI_OK=0
for i in $(seq 1 $RETRIES); do
if ping -c 1 -W 3 8.8.8.8 > /dev/null 2>&1; then
log "WiFi ready after $i attempts"
WIFI_OK=1
break
fi
log "WiFi not ready, attempt $i/$RETRIES"
sleep 5
done
if [ $WIFI_OK -eq 0 ]; then
log "WARNING: WiFi not ready after $RETRIES attempts, continuing anyway"
fi
# Start sshd
sshd 2>/dev/null
log "sshd started"
# Start cron daemon
crond 2>/dev/null
log "crond started"
# Start gateway (setsid for detach)

log "Gateway launched (PID: $!)"

- Ping target
8.8.8.8requires internet access, not just WiFi connection. If the router is up but WAN is down, the loop will fail all 12 attempts - The gateway starts even if WiFi never comes up (graceful degradation). The WiFi watchdog (Hack #46) will handle reconnection
- Boot log is written to
$PREFIX/tmp/which is tmpfs and cleared on reboot. This is intentional — we don't want logs accumulating on limited storage - The 60-second maximum wait (12 x 5s) is designed for the worst case. Most boots complete WiFi check in 10-20 seconds
Result
| Metric | Before | After |
|---|---|---|
| WiFi wait | Fixed 15s | Adaptive 5-60s |
| Boot reliability | ~85% | ~99% |
| Failure mode | Silent (broken gateway) | Logged + graceful degradation |
| Boot time (normal) | 15s (fixed) | 5-15s (adaptive) |
