Your project is to design a front badge for our bluetooth speakers looking like a vintage guitar amp. The name on the badge is "Zendling". We plan to have the badge manufactured in metal and with enamel inlays, so it could be a combination of metal and colour, maybe even more than one colour. However, the speakers may vary in their appearance, there will be "goldish" (like the red and beige one) and "silverish" (like the blue and beige one) variations, and there will be dark themes where the parts (e.g. the strings that separate the colours) will be either dark steel or even black. One single Zendling badge should - if possible - fit all these different themes. Don't get confused with the fact that the pictures are showing all silver (and not go...

Hi Hong Thiet N., I noticed your profile and would like to offer you my project. We can discuss any details over chat.

I want to develop walkie talkie between NRF52(or ESP32) Module and mobile app(Android).

The experienced Embedded Engineer is required to assist with the development of a portion of the product for the automotive industry. Details will be shared over the zoom call. The project may take time from a few weeks to a few months. Also, if collaboration if successful, more work can be provided. Experience required: Bluetooth Low Energy. BLE = 5.0 (5.1 ideally). Experience with Nordic MCUs (critical), ideally with nrf528323 and nrf52840. Experience with BLE devices on Central and Peripheral configuration. Feel free to reach out to ask questions.

The ultimate goal of this project is to develop a mobile application under iOS and Android that can interact with a bluetooth (Android and IOS) or USB (Android only) smartcard reader (ISO7861 compliant). The project will be executed in different phases. Phase 1: basic setup of the app (no interaction with a real SmartCardreader, only a mock of the reader) Phase 2: connectivity between the app and a BLE SmartCard reader on Android Phase 3: connectivity between the app and a BLE SmartCard reader on iOS Phase 4: connectivity between the app and a USB SmartCard reader on Android Note that the BLE device currently used is the ACSR3901SU. The details for phase 1 are described in attachment. For phase 1, we do not require that you have an experience with SmartCard reader...

Need to build a sensor that using two points could measure the variation of a small current flow (mili Amps) going through a material when affected by heat or pressure. Data must be send through a Bluetooth interface.. The device must accept some basic configuration and offer a simple protocol communication with the linked application through the Bluetooth interface. Even when the drawing shows a finished product layout, the prototyping could be done on any type of board.

I am a dance teacher and I need an APP that acts as a digital metronome, using the vibration system of the devices, for helping my students to understand the rhythms of songs. The main idea is to create a shared metronome using the Bluetooth and the vibration of the mobile devices. The Main Device creates a vibration pattern, touching the screen 3 times in a row. This constant Pattern is transmitted by Bluetooth to the other devices making them vibrate. Due to possible time lags, the app must be able to stop the pattern to create a new one.

...a swing (as rotated around to different angles on a 2D display). A properly operating software application is far more important first, and I have a couple of (Arduino-type?) hardware units put together by the most recent contractor that can hopefully be used. I have attached front and back images of one of the sensors for reference. While powered by USB cable, its data is sent wirelessly by Bluetooth, which is linked to my desktop. If it is important to know what any given components are and that cannot be made out on the images, please let me know. I would ideally like to proceed in two broad steps from here. First, I would preferably like to learn how to access all of the raw parameters and parameter data values the sensor is capable of providing when in use, be able to see ...

So in short I have a system similar to foodpanda, Uber eats and so on. The restaurant have a tablet or similar in the place. I need the possibility for a Thermal Printer to connect to it. It's a Web App (VueJS), so it might not have access to etc. Bluetooth. It's a PWA and therefor web based. So there are some possibilities: 1. Look at and their plug-ins for what has already been created or used () 2. Foodooma also has a thermal printer module: () 3. Check and how to utilize that 4. Check PaperCut Mobility Print 5. Setup a print server with a Raspberry PI as a print control box/ print server. I need the best and easiest solution
