Need to develop fimware

Hi, how are you doing. i ve been working on IoT project for a while now. i ve worked with firmware for Bluetooth modules, wifi modules and 3G for communicating with IoT Servers. If i understand, you want to create a board based on microcontroller and a weighing sensor where you send commands through Bluetooth from the android app to the electronic board to measure the weigh what did you mean, to process via internet. do you mean that the 'smart scale' and the phone with the app are not in the same location, where you need to send data through internet? The way i imagine this , is the smartphone app works as an interface for the scale, where data is fed continuously to the app, once connected, the screen of the app will be an online reading of the scale. work will be done as follow: -set specifications, range of weighs, 0kg to 30kg for example, -choose the right sensor, chip, and bluetooth module. -design a prototype PCB for the product. -Program the chip to read the measurement of sensor and bluetooth communication -Test and valid the prototype
