Technologies: ESP8266, MQTTS The library and example should run on a ESP8266 I will not consider negotiation after a bid is made. If you have questions, ask first. Do not BID if not certain of the price. Discovery and setup: - An library that connects to a IoT platform that will be provided to you ([login to view URL]) - This library once instantiated should connect to a server (provided to you) and obtain it's own identifier - This library once instantiated should make the ESP8266 discoverable on UDP broadcast - This library should react to a discovery request from a smatphone app (provided to you) and follow a pairing process (calling some HTTP endpoints provided to you) - This library once instantiated should follow an Authentication, authorization process - This library once instantiated should connect with the obtained credentials to a MQTTS server - This library should save locally the obtained token / credentials and maintain the same (eg: token renewing) After discovery: - This library is used to receive and send data from / to an IoT platform - The library should pass to the developer space all the received events from the cloud - This library should have a method to send events to the cloud - This library should know how to compose the json format that the IoT cloud knows. Configuration variables - A set of configuration variables should remain on a config file.h - A set of runtime configurations should remain of local storage inside a json object You should provide a simple .ino example where: - The library is instatiated - There's an event received from the We will provide the full flow process and the endpoints.

Hello " - This library once instantiated should make the ESP8266 discoverable on UDP broadcast " I can't get this point, why this is needed ? Discovery of the chip can be obtained by making an AP network , while connecting to the Cloud (server) is through HTTP requests so why UDP ? to receive from the server ? MQTT provide a full duplex connection , so .. no need for UDP after establishing MQTT conection And if you need the server to send to the chip before the MQTT connection , then may be the best way to do it is an Open Channel (web socket) instead of (Open-Close Channel) like HTTP Requests . BTW .. May be this project is a candidate for RTOS_SDK , but yes , it can definitely be done by Arduino Core If you have no problem with my Bid , please provide a detailed description of the steps

I already have few firmwares for MQTT specific to your board. and I can modify it for your application. I can also create your own cloud server with all the features with a front end for controlling and data visualization. I am an IOT Developer with an expertise in Embedded Systems and Cloud Deveopement. Would love to hear back!
