    ...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 on MQTT broker. The design of the screens is to better sectorize, hierarchize the information and make the information more user-friendly. The app is already launched, and I have the initial p...

A React Native app is functional today, but has some very minor bugs, and misses a few features. This initial small project will be used to verify if we can work together - If we can, I expect much more work over time on this project. You must have access to Android and iOS hardware, so that builds can be tested on device. Experience with MQTT protocol is a plus, as the majority of app communication happens through this protocol. However, it is not a strict requirement as much of this is already in place. See attached description of init...

I want to connect an Arduino Mega 2560 with a SIM800c module to AWS IoT core using the MQTT protocol with authentication and be able to send and receive messages between the Arduino and AWS. I am seeing that Mexico has very bad 2G reception, so I was looking into other modules with 3G or 4G as well. I'd like to know if you recommend something for this as well. Thank you! Leonardo

    There will be 12 LEDs. During a round, each LED will light a single color out of three. These colors will be red, blue and white. The player will have three buttons to press and he will have to indicate which was the priority color. If it hits, it moves on to the next round. If you miss, the game is over. To make the game more difficult, at each round, during an interval of 5 seconds, the LEDs must flash faster and faster. I need this prototype ready in the next 12 hours.
