8 Software architecture
8.1 Overview
Ivativ provides AT commands and binary APIs for Ivativ Host Interface Software (IVHIS) over UART. This
architecture uses s140 SoftDevice from Nordic Semiconductor. AT commands are issued from the
external host to the RENO module over UART interface. User may use any serial terminals like Docklight
or Putty, Mincom, Cutecom application to send AT commands.
This software allows BLE modules to advertise, scan and connect. It supports GATT server and Client
features. Using this software user can configure BLE, perform ‘Over the air firmware upgrade’ and
program GPIOs.
