About this app

ZenAir is a tool for communication with microcontrollers (Arduino or ESP in particular), websites/servers or other devices with IP via WiFi, MQTT or Bluetooth.

All using entered devices are on the screen called Terminals. There is 2 view Terminal types: CLASSIC and GRID. GRID one provides you possibility to place items/panels on screen and configure it with editor mode.

Advantages of app:
— No Ads and paid features
— No telemetry, works completely local
— JavaScript runtime engine J2V8 to modify data
— Grid Terminal that gives ability to place items as you want
— Import and Export by Text (Base85) or Image (Data Matrix) between users
— Locator with SSDP: to search your IoT devices in local Wi-Fi & get embedded Terminals
— Fully configurable, fast and compact interface
— Autosave with adjustable rate
— Auto Connecting (at App start)
— Auto Reconnecting (at unexpected disconnect)
— Can working in Background
— Keep-screen-on (preventing device from sleeping)
— Line-keeping: In moving console, keeps the line which you stay on
— Most unique Linear Chart item

Here is main items of CLASSIC Terminal:

History — records an actions related to the interaction between devices. It is possible to remember data that was sent by user and/or received from device. The size of the history is determined in the settings with maximum of 9999 lines.

Slider — supports joystick mode, automatically sends 0 (with prefix if it exist) at the end of usage. It is possible to set any prefixes. Minimum —2^31, maximum 2^31 — 1. The count of sliders is limited to 16.

Button — it is possible to send commands as long/complex as possible. Pressable button mode with configurable sending rate is supported. Auto—clicker is supported like click at a certain interval (at least every 15 minutes) or once a day at a certain time, this is an experimental function that doesn't necessarily to work as it should. The number of buttons is limited to 60.

Input field — just a single line field. By default, all data is sent with the ";" terminator (can be changed on settings).

Console — all incoming data displays here, previous line can be stacked with next. Maximum size is 9999 lines.
