Mobile APP - ioT devices

The scope of work is to remodeling an APP based on an existing version, that is already in place, changing some things and add another functionalities. All source codes will be delivered as the icon images in different formats. Basically we need a freelancer to provide a new version of this APP. – “Sources in Ionic 3” This APP communicates to a HUB trough a WiFi router or Access Point. The Hub receive all requisitions from mobile APP, make treatments, and send information’s to the other devices via WiFi link, that are present in the same network. A new function called: “Discovery” (UDP Broadcast) must to be implemented on the new version. This function will be used when a principal hub is not present or down. In this case, another device can be used as a hub if this function is present on his firmware. Also the APP must to have capabilities to store IP address from a present HUB and make renew search periodically. A new function called: “Setup Screen” must to be created in order to insert manually HUB ip address in case of error or limitation of the device or network topology that limits the Hub discovery protocol. Also multi Language functionalities must to be in place. A full document and information's will be delivered after bid finished.
