Comments on Serial USB Terminal for Android

★★★★★ Tech Nineteen · Jan 29, 2025

Great app, it's my go-to app now. I don't need to carry a laptop just a USB-C to USB A cable adapter. One thing that would make it even better would be Ymoden. The ability to receive large files would make it a 6-star app for me.

Edit: default save data folder is inaccessible. Go to settings/misc and change custom folder to whatever you want, I use documents. Then you can view saved logs and data in file browser 👍 Perfect terminal for Arduino projects! I just used this to help develop a bio-based steering wheel control interpreter in my car. The ability to write code which responds to terminal commands has made it so much easier to test and debug my contraption in the car without a laptop, which I don't have.

★★★★★ Brian Blakley · Mar 18, 2024

Very handy for sending serial commands to devices and viewing serial data outputs without needing a laptop. Thanks!

Not usable. App freezes when you have something plugged in and hit any of the buttons on screen.
