Here is a proof of concept which leverages an ESP32's Bluetooth capabilities, the great library https://github.com/T-vK/ESP32-BLE-Keyboard , and your existing computer/iPad/whatever's display as an output debug terminal - much like a serial monitor which is USB connected, only wirelessly and without the need for WiFi to be connected.

For example, you could have a solar-powered weather station outside, and want to be inside watching a debug log of it running ...

... and guess what, if you have an ESP32 you quite likely already have all the hardware you need for this.

Proof of concept code is attached and can be found here too: https://github.com/roblatour/BlueSerial

Of course, you can get more sophisticated, for example, add a toggle switch to your ESP32 project which when on signals your project to transmit log items, and when off doesn't.
