Bluetooth beacon appcông việc

Currently we are experimenting with a proof-of concept web app written in Node.js that acquires the samples via bluetooth web api, calculates signal spectrum with FFT and displays both the raw signal and spectrum for one channel. Google graphs are used for drawing the signals. It seems that the web application as we have currently created is not optimized well as it barely manages to refresh the graphs at 10 or so fps for only one channel on an average modern laptop.

Hello, Im looking to make a RF transmitter. Which can be switched via a magnetic reed switch. Transmitting @457khz +- 100khz. To Fit on approx 1"sq is for tracking of cable run ferrets up to a distance of 20ft and with a battery life of approximately 10hrs. The reason for this specific frequency is to be recieved by an existing reciever such as an avalanche beacon or Deben Ferret Finder. I WOULD BE VERY INTERESTED IF SOMEONE COULD DESIGN A TRANSMITTER AND RECIEVER THAT OPERATE IN THE SAME FASHION/PRINCIPLE OF A DEBEN FERRET FINDER MK3.

...recording to my office application, it is an internal application and will not be posted on the Apple App Store or the Google Play Store. My application is built with Dart/Flutter and I will need a service which I will add to it. Requirements: - The API (GraphQl) for the service will be decided before the project is assigned. You will provide a suggestive required graphql API. - The tests, both unit and integration will be decided (Just test names & docs) before starting any actual code work. Again, you will have to provide your suggestions first. - Service must work for Bluetooth headsets, earphones, external speakers etc. Must also work for device switching, eg: turning on speaker or Bluetooth in between calls. - Service must work for Android 8 and above, inc...

Hello, We have an App on Android called Adaptalux. We are looking for a developer to implement code to the app for a new Bluetooth communications stack we have developed with one of our products. We have the entire app stored and is already available, we need the code relating to the new bluetooth protocols adding so it works with a new product that uses a new bluetooth module. All of the bluetooth data is already written and working with iOS, we just need it adding to our Android app. Basic Details are: 1. What programming language is used for the Android app? The Android version of the app was built using Java, the iOS version was swift ( originally v3 but I think I updated to 4 or 5 ) 2. What platform has bee...

Android or iPhone application to control an output of an ESP32, using Bluetooth BLE. The communication between ESM32 and the phone (will be Android or iPhone) must be encrypted. The ESP at programming will have programmed the encryption Key. I suggest the encryption key to be the MAC address of ESP. Encryption and details will be determined later, but must be a strong encryption. Principle of operation: User download the application and install it on the phone. When user click on the shortcut of the application, the first screen open. It is the setup screen. The user must enter a 7 – seven-digit code. The digits show as ******* and not numbers. Then a command will ask him to enter the code again. If the code does not match, cursor move and flash on the first line of code waiti...

The most important characteristic of any developer is persistence. Even if you are a junior developer and you can do this... Get the Code: Checkout, Build, & Run Chromium ...please apply. Here is what we need: Currently for a Web Bluetooth connection the browser requests a service through a JavaScript call: let device = await ((filters: [(services: [serviceUuid])])); This call brings up a Bluetooth pairing screen that displays all devices broadcasting the specified serviceUuid. The user selects the right device from the list and the server provides a reference to the service: let service = await (serviceUuid); Specific characteristics can then be obtained from the service:

I have my own project And print receipts on Bluetooth printer. But now i need to print order to network project

What I want to do is get data from a Main board (Custom uC with sensors) via UART and connect it to the UART set pins (29 and 31) of a nrf52840 dongle. This in turn will send the information to a DK nrf52840 via bluetooth and the DK nrf52840 will be connected to the COM port of a laptop to view the data on a serial terminal. I want both (DK and dongle to connect automatically). I want to make this link since the main board and the dongle will be in a place of difficult access and through the ble link with the DK I will be able to observe the data in a safe place.

simple assignment for adding a bluetooth feature to an app that I already created.

Network Traffic Analysis Using Wireshark, capturing live traffic from it. Wireshark captures network traffic from Ethernet, Bluetooth, Wireless (IEEE. 802.11), Token Ring, Frame Relay connections, and more. Processing the traffic dataset, we can process the traffic or the packets collected in two ways, ie by applying filters commands or PID method. From the processed dataset working on the visualisation, creating a dashboard, statistical information, showing trends and more about the data. Intrusion Detection System This software application is to monitor network traffic for malicious activity or policy violations. If there is any violation it can be reported to an administrator. Creating a firewall in Wireshark to protect the malicious traffic flowing into the network.

Hello freelancers, I need to design a multiplatform application for the opening of a valve. It will only have a dial to mark the opening degree and two buttons (one open and one close). This application will be connected to a nodemcu by bluetooth. The hardware design is already done and it would be necessary to connect with it through bluetooth sending the necessary characters to make the interface. The valve is used to regulate the sound of the car, when it is open, the exhaust pipe is completely open and will make a lot of noise and when it is closed it will not. The design of the application must include my logo and must be with the theme of cars, which is what it will be used for. I would also like if it could be uploaded to the apple and android marketplace so that it c...

Looking for an app to be developed based on our specifications - we can be okay for beta version due to sending it out to investors. The app pairs with an IoT product in development as well so it would need to be able to pair with bluetooth/RFID and other firmware and software issues. Right now though, we want something basic to show people in order to gain investment for future final app development (if this arrangement goes well - we could use you for future app development as well).
