How to update over the air?
Posted by Squarell Support on 27 September 2016 04:04 PM

There are 2 ways to update DCFs and firmware Over the Air (OTA).

Core API. (via Canbus or Rs232) 

This is the method iUpload uses to update DCFs and firmware. We prefer this method because its very powerful and fast.This protocol can be performed regardless the DCF installed on the Squarell device. The only downside is that you must be able to update your modem firmware and that your modem has free RAM to have the DCF or firmware so it can be send over. Also, your modem must be able to process non ASCII bytes.

DUP protocol. (via RS232 or Bluetooth)

DUP is an easy to implement and use update method. It is less powerful than the Core API but if your modem is not able to send binary data or if you are not able to update your modem firmware this is the way to update. You can also use DUP by Bluetooth. You can just send some packets/messages from your server to the modem which forwards it by RS232/Bluetooth to the DCF in the Solid and when all packets have been received the device will automatically start the update.

All our Profiles, DCFs and firmwares that are available in iUpload and Expertview can also be accessed by you with help of the ExpertView webservice. How it works is described in the ExpertView webservice manual.
