The project is a children's toy racing car system app for Android specifically for DFU purposes. In the toy car is a wireless PCB featuring Nordics nRF52810. The toy car is able to have its firmware wirelessly updated via Bluetooth using a smart phone. The end user downloads the latest toy car firmware from our website and stores in files on phone. The user runs the app and scans for the device, enters it then adds file to box where the latest firmware upgrade is uploaded to toy car. The iOS version has been completed and is available to look at via video and Testflight (Apple) Video here: The PCB is in prototype stage and only ONE exists. It cannot be sent to the app developer. Part of the agreement will be that my company will carry out all beta testing

I have tried to add as many details as required to understand the scope but I can be available if more information is required. The Background: I have a product that uses HM10 as a Bluetooth communication device. It sends received commands to atmega328 which in turn turns a light on or off (and does a few other things based on commands). Commands are very simple we have added Arodino code to run commands and achieve the desired functionality. Mobile apps: We have two native mobile applications. One for Android and another for iOS. Both worked fine until recently. The right hardware: We were using HM10 which was working fine with both iOS and Android. When you run the AT+VERSION command on this one, you get a response:"MLT-BT05-V4.45". This hardware has the attached me...

Want to know Bluetooth Mesh Performance (sender rate/receiver rate): * send-demo: write a test program for nRF52832 DevKit based on Zephyr BTmesh stack and post 40 Gonoff Set Unack messages over mesh (no transmission repeats, relay off). App should reach 40-50 packets. Need to know Config settings for Zephyr stack. * receive demo: extend send-demo to have both send & receiver capability. By proper mesh model configuration sender and receiver activity can individually be activated/deactivated. Additionally packet sender rate can be increased/decreased stepwise with button presses. Now use as many boards for sending and 1 board for receiving to demonstrate 200 packets/second receiver packet rate from Bluetooth Mesh.

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.
