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 request/response topic

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...

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...
