At the first boot the HS402-WIFI oscilloscope creates an Wifi access point with SSID like
HS402-F62684. Connect to it with the phone or PC (password:
123456789) and open the browser at address 192.168.4.1 to access the oscilloscope configurations.
In windows you can find it also under Network. Double click on the icon to open the configuration page.
In case you cannot see the oscilloscope in the Network list, in the wifi list just open the preferences of the HS402 wifi and set it as Private since Windows block the device discovery on public networks.
- Remove WiFi automatic connection to strong network in Android. In this way the oscilloscope won’t disconnect if the Android tablet detect a stronger WiFi connection.
The RGB led connected to the ESP32 development board provides the status of the oscilloscope.
AP Mode: the ESP32 is itself an access point, you can connect to it directly by searching on the available Wi-Fi. SSID like
STA Mode (Station Mode): the ESP32 connect to an existing access point / router. The phone / tablet should be connected to the same network to connect to the oscilloscope. You can configure this mode in the ESP32 Webpage.
In case you forgot the password of the Wifi in AP mode and cannot access the configuration anymore, just press the
BOOT button to reset the configuration to the standard values.
- Press and keep pressed the
BOOTbutton for at least 3 seconds. The LED will blink in yellow color.
- Release the button, then the LED will blink in red color to indicate the configuration update and the ESP32 will restart automatically in AP mode with the default SSID name and password.
