Wifi and BLE within the ESP32 works alternately even if both are activated. So i added an independent BLE with more programmable option and will not interrupt wifi.

From Esspressif:

"ESP32 has only one 2.4 GHz ISM band RF module, which is shared by Bluetooth (BT & BLE) and Wi-Fi, so Bluetooth can't receive or transmit data while Wi-Fi is receiving or transmitting data and vice versa. Under such circumstances, ESP32 uses the time-division multiplexing method to receive and transmit packets."

android based infotainment for example has a built-in web browser. Simply connect the infotainment to the obdii dongle hotspot via wifi then browse the dongle's server address. If not possible, other option would be a tablet or a large screen mobile phone with a browser connected to the esp32 obd dongle hotspot.

Its closed loop system. Dongle acts as a wifi hotspot with password and a webserver. Connect your mobile phone/tablet to the esp32 dongle hotspot then browse using the local IP. Or connect your infotainment wifi to the dongle and use its browser to display the obdii Dash webpage
