The easiest OTA firmware update

Missing an ability to update your devices?

Fearing that new firmware can hang or crash?

VCON solves both problems!

Device dashboard

You can update VCON modules remotely at any time using a secure device management console. Uploaded a broken firmware that crashes or hangs? Don't worry, you can reflash it in seconds! Supported firmware formats are .bin, .hex, .uf2.
The management dashboard with REST API allows you to monitor your fleet 24/7.

Remote communication

Remote communication

You can forward Serial port of your microcontroller/device to any MQTT or Websocket server of your choice. No need to write a single line of networking code. For example, you can send sensor data to AWS IoT simply by Serial.print(data)
Or, do you want to register your own custom management functions in the Arduino sketch, and call them remotely via the REST API? You can do that too. Yes, without a single line of networking code!

Ready-to-go recipes

Looking how to send your data to AWS Dynamo DB, or Firebase, or your private SQL database? Or how to send an SMS alert when sensor value get out of range?
