- connect your Arduino to the phone using OTG cable
- access it using netcat in Linux

Supported boards / chips:
Arduino (original and clones)
ESP8266 boards
ESP32 boards
NodeMCU
ESP32-CAM-MB
STM32 Nucleo-64 (ST-LINK/V2-1)
FTDI
PL2303
CP210x
CH34x
many CDC ACM devices

Connection:
Phone must have USB OTG function and be able to provide power to the connected USB device (most phones nowadays).

Ratings and reviews

I found this to be a handy little app. Only issue is battery drain. After closing the app, it will continue to run in the background and drain your battery. So after use, you need to kill the process (via settings) or reboot the phone or tablet. If you change your settings to not allow this app to use battery while it is in the background, then the app will not work correctly. So, give it unrestricted use of battery, but make sure it's "process" is not running after you are done using it.

Simple and effective! I use it to drive the CNC milling machine from the PC via an old Android phone using the wifi connection.

Great application. Why it stops server after 5 min. There is no pro version. I would buy it if it exist. Great for Ham software DV Blue with DMR Station interconnection. Exelellent job. Pitty I have to uninstall it because of server interupt. OTHERWISE GREAT SOFTWARE!!!

What’s new

Fixed bug in USB drivers.
More boards are supported now, including ST-LINK/V2-1 found on STM32 Nucleo-64 boards.
