Business сhallenge

  • SumatoSoft was responsible for the front and back-end parts of the project. There was a liaison between a manufacturer and us. 
  • A liaison’s goal: to deliver a fully functional product within the agreed interval of time and scope.
  • Manufacturer’s goal: to sell a new AC package with extended control (via iOS and Android apps and a new AC remote control unit).

Our solution

SumatoSoft team developed simple and neat native iOS and Android applications according to the requirements. Apps connect directly through BLE to the firmware of the AR system and allow to control and manage the environmental conditions. 

We used native methods to establish a connection for iOS and Android app versions. The biggest challenge was establishing a connection for the Android app because of the variety of versions and gadgets Android has. However, we prevailed in this task. 

It was a new AC remote control unit concept. This version of AC RCU became widely distributed on the Chinese market.
