One-Line Deployment

PASSWORD='your_wifi_pass' ./mass_deploy_enhanced.sh ~/Code/esp32/esp32-iperf

Common Commands

Deploy 32 devices

PASSWORD='mypass' ./mass_deploy_enhanced.sh

Test all devices

NUM_DEVICES=32 ./test_devices.sh

Custom IP range

PASSWORD='mypass' START_IP='192.168.1.100' ./mass_deploy_enhanced.sh

Different WiFi network

PASSWORD='newpass' SSID='NewNetwork' GATEWAY='192.168.2.1' START_IP='192.168.2.50' ./mass_deploy_enhanced.sh

IP Address Scheme

Default: 192.168.1.51 + device_index

• Device 0 → 192.168.1.51
• Device 1 → 192.168.1.52
• Device 31 → 192.168.1.82

Time Savings

• Old way: 60-90 minutes for 32 devices
• New way: 15-20 minutes for 32 devices
• Speedup: 4-5x faster! ⚡

Troubleshooting

No devices found?

ls /dev/ttyUSB* /dev/ttyACM*
sudo usermod -a -G dialout $USER  # then logout/login

Flash failed?

BAUD_RATE=115200 PASSWORD='pass' ./mass_deploy_enhanced.sh

Can't ping devices?

• Check WiFi password
• Wait 30 seconds after deployment
• Verify network supports static IPs

iperf connection refused?

• Device still booting (wait 30s)
• Check logs: cat /tmp/esp32_deploy_*.log
