We have a medical app that allows us to capture data from Bluetooth devices. We are looking to add a new feature that allows the user to take a photo of of a medical device face plate. We want to have our app scan the image and find numeric values. We also want the app to find character/labels that indicate what the numeric value is associated with. For example, if we take a picture of a blood pressure devices, there will be three numbers (120, 80, 55 - these are examples). Near the 120 value in the image, you will see "sys". This means that 120 is the SYSTOLIC measurement of the blood pressure. For 80, you will see "dia". This means that 80 is the DIASTOLIC measurement of the blood pressure. And for 55, you might see "hr". This is the beats pe...

PLEASE READ THE DOCUMENTS. DO NOT SAY, I AM INTERESTED SEND ME MORE INFO! I will not respond. If you have specific questions - send them listed by number.

The PCB should hae capability to connect relay to external motor to turn ON or OFF 3) The power input, data input and data output support should be there for PCB 4) The PCB should also be capable to support power 3.3v for 2 sensors.( Sensors

Need to make a very simple app for remote control via Bluetooth and Internet. Core things which will be needed to figure out - Background app refresh - Bluetooth connction - How to keep the app alive even with elongated periods of being in the background - How to make sure the controls work even if another app is in the foreground and active - Needs to be a simple and very little memory usage so that the device does not shut it down for want for memory - will he likely 4-5 screens only - Need one app for Google play store and one for apple - ideally a single app - Will need a bit of design work as well - but the app is so simple that it should not be tough

Hi there - I'm working on a project that requires one or multiple weight scales / load cells to capture data on the current load and then broadcast it (I think broadcast? I dont know what other protocols are used for bluetooth BLE 5). The one other factor is that a RFID must be integrated as well to determine what is currently being weighed...and that information should also be broadcasted. Requirements for the project: - Must be tangible results...need to know how to capture inbound BLE content and prove your work. - You're responsible for gathering the required hardware. I'm happy to pay for the hardware up front if you can provide the hardware list. Let me know if you have questions. Honestly this is pretty easy...take data from two sources (load cell and RFI...

I'm looking for a basic Xamarin mobile app. The app has BLUETOOTH using the Nordic NUS serial service. It's a user interface for an industrial device. there would be one or two main screens and then a few menu screens with options. The program would need a database backend to store some config settings and recall them to send to the device. It will need to scan for and connect to the device over BLE and then allow the user to interface with the device using several commands to read/set values.
