Connecting phone to ESP32 with serial link

[extqblys]

Hello,

I am trying for several days to connect my phone to my esp32 but didn't find something working yet.
I have an USB-TTL cable with adaptor to connect my phone in the micro-usb port.

Can someone tell me if it's possible to communicate between ESP32 and phone without Wi-Fi and bluetooth ?

Regards,

PS: I'm sorry if there are some mistakes in my message, i'm not an english native speaker. Thank you !

It should be possible, but first you need to make sure you have the correct software/firmware in your esp32 (so it communicate with the outside world) and then install a terminal program on your mobile phone

If your phone support otg you can use an otg cable and a USB terminal app. I use this on my android tablet

I recently worked to establish a serial connection between ESP32 and Android App.
