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
From an existing Yocto version, we need to improve it by adding Bluetooth and CAN communications. The embedded plateform is a SMT32MP157F with a Cortex A7.

Proyecto de desarrollo de placas PCB con el procesador ESP32 para recibir datos via bluetooth y enviarlos por wifi a la nube de diversos dispositivos.
This is going to be a data logging App. It'll be able to connect with a car (through a Bluetooth dongle) and send all the necessary commands to the onboard control units to communicate with it and extract information in real-time. This information will be Simplified and displayed over the App in a predefined format. Some of the Apps similar to this (For example- carista, Torque pro etc.) are already available on the play store....you can check them out.
Restaurant waiter robot Components: - A robot trolley up to 5 trays - Ultrasonic sensors - Motor (big stepper motor) - Infrared - Speaker - Button - Wifi / Bluetooth - LCD display - Lithium ion battery The robot need to follow the line drawn on the restaurant floor and move in one direction only. The shop worker will use a mobile phone to setup the shop layout with table numbers, charging station and pickup station. A simple console and report need to be shown in the App to indicate the battery percentage, distance travelled and tables served daily. The App can be used to instruct the robot to self charge at charging station. After shop worker enter the table number for each tray and press Go, the robot will follow the line and send the food to each table. When arrived at the tab...

Information security is of key importance and therefore the infrastructure should be exceptionally difficult to infiltrate. All access rights will be predefined for set duration and all information captured will be sent to primary control center. Access will be granted through Bluetooth or NFC for now, however, other hardware compatibility such as biometrics and RFID should also be possible. 3 layers will be constructed for this program:• Top layer - Central command center will have access to all information and can control all access rights• Middle layer - Access to limited information defined by the ...

Drawings, schematics, and GERBER files should be included as well as a bill of materials, along with two working prototypes. Bonus: it would be nice for battery powered, while charging from the same one usb input. Estimated battery life should be calculated for 24VDC at 20 ma load for a period of 8 hours . It would be nice to have a custom enclosure. It would be nice to have a small display voltage and amps out, up to 10ths of a volt and up to one milliamp. Modbus tcp over wifi if using the ESP32 would also be nice. Whatever the device I will build a UI for the PC and/or phone app to use. Dependin...

Write a bluetooth device locator, like AirTag, Tile, SmartTag, Chipolo. Code with Xcode 13, Swift 5. The app should run in the background even if the app is closed. Display a notification to the user if Bluetooth or location is turned off. Store each received Bluetooth frame in an array. When the Bluetooth scan finishes, send the table of received Bluetooth frames with the longitude and latitude of the current location of the IOS device to a TCP socket server. After server aknowledge empty the array. Use the startMonitoringSignificantLocationChanges () function to make it restart even after restarting the device.

We're developing a product which contains an Arduino Nano 33 BLE (). We're using an original Arduino board, not a copy. We want to be able to establish a link so the product can communicate with an Android tablet. This is something new for us, so it'll save us a lot of time if someone can build an example for us.. which is this project. The example should include a simple app for an Android tablet and a corresponding app for the Arduino. The Android app should include a simple user interface including - a button to establish a connection to the Arduino or disconnect from it. - a text box where the tablet user can enter a string to send. - a "send" button which sends the string to the Arduino. - a received string box where a string send

It is an application where a user can select one type of event among several or a generic event to which they can add images, audio...or another technology that competes with them on price and effectiveness. The application must consider that a group of users update their location in real time with the lowest energy consumption. Other users will not constantly update their location and will only do so when creating an event or entering news It is desirable that the application, even in the background, allows the press of a bluetooth button to bring the application to the foreground and trigger a specific event. From the server side, the control of the user's status must be carried out according to the explanations that will be provided to the chosen company. Required platforms...

...pictures, silhouettes on a white background, and over the white area displays specific text relevant to the results of the sketch's operating on the variables received from the sensors. The sequence of events is triggered by using this touchscreen to post a query to get the new sensor values. An alternative display is found on the client's Android smartphone, and communicates with the Arduino via Bluetooth. [This method is preferred.] I have built a partly-functional proof-of-concept system, but I prefer to make another one, introducing one module and feature at a time, adding a new sensor or function only when the previous ones are working. The project would progress thus: 1) The nine preformatted .bmp images would be loaded onto the microSD card from the Windows 10-b...

I want to build scoreboards into my cornhole boards. I thought I had it figured out, but need help. I have already built the boards (photo attached) and bought what I thought I needed to light and control the scoreboards. I have them set up for 7 segment displays. I intend to put a small strip of 3 LED’s into each of the 7 segments on each number. So there will be two, two digit displays on each board. I would like one controller to control both boards at the same time. Score would need to run from 0-21. I am open to ideas on how to adjust the score. I have considered Bluetooth to iPhone but think maybe an independent hand helps remote would be best. All items I have are 12v. I have a 12v power source as well as 12v LED lights.
