IMT Link App

Dear freelancer, The main goal is to deliver an app (IoS/Android) for connecting to and reading out the WT20-Ex temperature sensor and (later) other sensors through Bluetooth. The WT20-Ex is used for temperature measurements on tank containers and tank wagons. It wirelessly connects to our communication terminals that relay the temperature measurements to the platform through the mobile network. However, some customers only buy WT20-Ex's and want to read out the logged measurements when the tank container is at a depot. The WT20-Ex and all other IMT sensors have a BLE 5.x chip and can therefore be used to connect to a mobile device. The WT20-Ex logs the temperature measurements in its flash memory, it has sufficient storage capacity for years of logging with 30 minute intervals. You will be working together with the embedded software developer of the WT20-Ex. High level Scope: - existing code base of IMT apps to be used, software to be developed conform the existing framework and methodologies (React Native) - existing branding/look and feel to be used - secured connection, by authentication on the IMT platform - easy use - display the temperature readings in a table (timestamp, temperature) and in a graph, within the app - send the readings to an email address - send the readings to the IMT platform, so that I can view them later in the web application
