About UART Terminal - connect to Arduino via OTG
Communicate with your Arduino, ESP8266 NodeMCU, ESP32 or other MCU or device like 3D Printer, CNC, etc. Just connect to the OTG USB port of your Android device.
User can select ASCII / HEX mode separately for terminal screen and command input.
User can also select the command ending (the characters to append at the end of each command).
Local echo option: to also see what you sent.
Baud Rate selection: any integer number, not limited by app, but make sure the connected device supports what you enter.
Char Delay option: for slow MCUs - wait a given number of milliseconds after each sent byte, so the connected MCU has enough time to process it.
Make sure your connected device is supported, before buying this app !!!
You can test it with our free app TCPUART
