Seeking a freelancer to design our project. We wish to take readily available scales the have BLE 4.0 and leverage the new BLE 5.0 protocol to implement the mesh and beacon abilities within the product development. The scales we have access too, already have the ability to send weight we want to add temperature and battery/charger voltage to be sent to an app we want to develop. The micro-controller used must allow for FOAT for all scale devices to assure timely updates to scales when required to address bugs and compatibility issues. Take out the BLE 4.0 install BLE 5.0 with microcontroller and give me #1 Weight data #2 Temp data #3 Voltage Data All to a simple app interface that we can have the SDK and BLE source code #4 Make it so the NEW BLE 5.0 Scale will use the Mesh network protocol so we can have many scales communicating and later we will work on pushing that data to a final App design and then a Web page for our clients This scope DOES NOT INCLUDE Web Development at this time but the BLE 5.0 Scale and Simple App you make MUST be capable for us to modify SDK and Have the BLE 5.0 source code so we can implement a cloud-based scale solution, Basically Please quote taking two scales like this [login to view URL] Scale capacity 3-180Kg + / 396lbs + Embedded Temperature sensor in the top of Scale, Temp sensor does not need to be of high accuracy. Must have Constant power supply adapter plug for wall power or rechargeable battery pack The scale must read in KG and Lbs Client option The scale must offer Tare weight The scale must have the ability to calibrate Scale weight and Temp offsets from app to each scale The scale must implement BLE 5 Mesh capabilities The scale must be configured to provide beacon announcements ( details of announcements post NDA) ? Operation: BLE 5 connectivity of an or all scales via a gateway to Network and App accesses. The app will allow clients to set Weight and temperature alert and power limits with Email and TXT notifications.
