We need to [develop / improve / finish] an Android app that interacts with Bluetooth devices. The device is a portable datalogger. Currently we have a semi-working app that is able to interact with one Bluetooth device. We need to finish working out the bugs and expand this functionality to make the app download from up to 6 devices in close proximity (i.e. connect and download from 1 device, when finished, start downloading from device #2 automatically, then #3 and so on). Each device can have approximately 150k data points. Current app version include this features: User selects the desired device Connect with a single Bluetooth device Get the device status (ie bat level, sampling in progress, etc) Start / stop sampling process (sample means enable device to store sensor data to internal memory) Download acquired data and clear memory Show XY chart of the data and export to CSV file We need to break the work into 3 milestones: Milestone 1: Finish fixing bugs when working with 1 device (mostly cosmetic, random crashes when working across new/old androids) Milestone 2: Multi device implementation. We need an app to work with multiple sensor same way it works with a single sensor. That means, user would be able to select up to 6 sensors on the screen. Then, if the user taps “Start sampling”, app should connect with each device and send a “start” command one by one. Same for stop, download, memory status etc. Milestone 3: Improved user interface (TBD)

Looking to create a prototype for a Bluetooth based device that can be remotely controlled from a mobile app. You'll need to have a proven experience of creating a low voltage devices, be comfortable designing circuit boards and creating a prototype. Big plus if you created a similar integration between IoT (Internet of Things) and mobile apps. You will not need to create the mobile app but you'll need to work with the rest of the team to enable the platform which the will run the firmware. Do you enjoy working with Microcontrollers such as Arduino or Raspberry Pie? Then this project might be of interest to you.

I want to design an iPhone car mount with wireless charging, powered with Solar Energy. First of all I need to design the product. Which is a iphone car mount that can stick to the windshield of the car and use solar energy to generate power. The mount should also have magnets. Then I need to design an iphone case with magnets so that the phone can hold to the magnets of the mount. And finally the case should have an adaptor that can wirelessly charge the phone. There are some existing similar projects. So if the idea is not clear, I can send you links to some products that are similar.
