Click the install button and choose the port that the ESP is connected to. "Erase device" is optional and will clear all your settings.
Wait until the process is complete.
Once completed you can configure your WiFi settings with console (enter Wifi number from the list and password) or connecting to a temporary configuration Wifi network Arska-XXXXXXX and going to url http://192.162.4.1/ (admin/arska) with your browser.
If needed, enter new configuration or restore previous configuration from backup.

Troubleshooting tips

Download files for install over WiFi

If you do not have a cable connection to your ESP32 devices and want to update existing Arska installation over wifi connection, select version and download files (firmware.bin, littlefs.bin) from the links below. Then goto Arska admin page and select Firmware update (takes you to url http://[ip address]/update) and upload both files starting from firmware.bin. After firmware.bin update Arska tries automatically update littlefs.bin, so manual update of the second file may not be needed. Always backup you configuration before updating firmware.bin file.

Installation troubleshooting

You can get error message "Installation failed - Timed out waiting for packet header" even if the installation was successfull.
Resetting the serial connection by disconnecting and reconnecting the cable helps in some problems. After that press the "Connect" button to retry.
On esp32lilygo-4ch may need to press Reset button while starting the install.
On esp32wroom-4ch-a board you need to have IO0 pin connected to ground pin (GND) during upload, but disconnected normally.
Set LilyGO T-Relay S3 to upload mode manually by 1) pressing BOOT down 2) push and release RST 3) release BOOT. After upload press RST.
if you have strange problems, changing the cable can help.
