Briefing The app is being developed to access information from an ESP32 device, which has a water flow sensor. ESP32 records water consumption and the app presents this data in the form of a bar graph. At this stage of the project, I need to implement the initial configuration of the ESP32 device using Bluetooth, as the link (), in addition, implement the MQTT to access the ESP32 device via MQTT Broker on the internet and the redesign of the screens. I developed the app's initial flow to make it clear what the app needs to check once it's started by the user, after that it's simple, the app already knows the ESP32 device via mDNS or MQTT Broker, with that, the app must do HTTP GET/POST via mDNS on the local wi-fi network, or via r...

...android native application that is including two main capabilities. Context This Android app is a native application with two main capabilities: 1. Displaying a programmed sequence of images and videos on a device, display/screen. 2. Counting the number of people looking at the camera or in front of it. The app interacts with the screen, the camera and Orangead’s cloud infrastructure. Usage Modes These capabilities are used independently or together, depending on the configuration of the application. For example, a configuration might only activate the player module of the app, while another configuration only activates the detector module, while a third configuration might activate both. The app is programmed in such a way that the detector and th...

I need an Arduino based program for hidden mesh communication over wifi + Bluetooth for ESP boards where one of the boards will be acting as MQTT Server + (MQTT Client for another MQTT Server) and in case the local MQTT Server (one of the boards) is offline, then the other boards will communicate through the mesh without affecting their communication and functions. All boards can be programmed OTA. The boards that have Nextion screen can update and send the graphic file OTA. Boards can communicate over Modbus (Wifi+serial) for the related points while the board with MQTT Server can report all the MQTT points over Modbus too. Web server with custom password for assigning the required parameters like wifi, MQTT, name, nextion file location for upload, arduino file for upload,..... Ad...

The Bluetooth device would attach to a board used for kiteboarding. It would measure the speed and location of the board. Combined with a smartphone or watch, it would record the GPS tracking information to be displayed on a map. Take a look at the Woo and Surfr apps to get inspiration for the mockups. Woo: Surfr: In addition to screens similar to the ones in the Woo and Surfr app, there should be a screen to display the last known location of the board on a map. I would like mockups for both a phone and a watch.

Need a software/firmware developer that can program an OBD2 Bluetooth dongle to communicate with an ios/android app

I need your support. I have developed a sensor that wakes up, measures, sends the values and then goes to sleep again. The sending over Bluetooth does not work reliably. Only in 3 out of 5 cases is the message received by the Test software. I would like you to take a look at the class and run it on your hardware. Then you will see that an error message is thrown. You will then see that not all messages arrive. I want the messages to arrive completely. I outsource the complete Logic to my own lib, which then contains BLEDevice.h and BLEBeacon.h as external libs. The problem lies in the application of the external libs in my own lib (you could also call it a class). Unfortunately, it only sends the beacons unreliably. In addition, there are always warning messages. I would like t...

Okay so there is an arduino that has a sensor connected to it. This sensor should measure the heart beats and record the sound (from the microphone that is already attached to the arduino) The coding part: a website or an app should be created that has a username and password. Once you login it'll let you pick between a doctor and patient. If you click on the doctor dashboard you should have access to the patient file where you can access their heartbeat sound and their calendar, and the arduino device should be connected by Bluetooth to the doctor part of the website and it should record and store the readings for each patient. The doctor should be the one to add the calendar. If you click on the patient's dashboard you should also acess the calendar and heartbeat ...

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...

The receiver will have an LED that will turn on when it receives the signal.

We've developed a mobile app for Android. It's a point of sale app. We wish to add the functionality of printing different receipts using a thermal printer and the invoices (A4 format) using a desktop LAN printer. For the connectivity, we want the printing module to be able to connect to different printers (thermal and desktop) using Bluetooth, WiFi or USB. there will be some UI to develop in order to add a new printer, configure or delete the old ones and to choose what printer to use. We want that the printer module be delivered in a stand alone package (a jar file for example) that we can integrate to our project.

...have an existing app which needs a design upgrade but i don't have the time to do it myself. In the attachment you see on the right side how it looks right now. Your job is it to make it look similar to the picture on the left side. BAsically you should use the text on the right side and make it look good. As you see on the left side :) The app is based on this open source Bluetooth serial monitor: If you are up for it and can do it fast. Let me know. If you can solve these two issues. That would give you a tip: 1. This app scans for Bluetooth devices. But it only shows devices if i manually give Location Permissions to the app (Under Android settings). Can't the app don't get these permissions during install? 2. This ...
