Effortless remote control
VCON provides WiFi, Ethernet or Cellular connectivity and exporting your microcontroller's UART to a Websocket endpoint or or to an MQTT server (transparent UART bridge). Your Arduino can talk via UART not even suspecting it is connected online.
Effortless remote control
Ready-to-go management infrastructure
Together with OTA updates, you get a device management service for remote device control. All tested on numerous live products.
Use it and concentrate on your product rather than spending time and money on developing an infrastructure.
