requirements title: to implement the code for esp32 mqtt bridge using c programming language and painlessmesh library as per the following details abstract: this project using ESP32, MQTT & ESP32 WIFI MESH network technology only professionals on the above fields may apply in this project please have a look on the diagram which illustartes the general idea of the project requirements details: as per the diagram, we have an esp32 wifi mesh network, required to send commands to esp32 nodes in this mesh, so that we can turn led on/off using mobile application, every mobile device can turn led on/off for only one predefined esp32 node in the mesh network, in other words it's a one to one relation between the mobile device and the esp32 node, when the esp32 node get the command it sends back acknowledge to the same mobile device required to implement the C code for the mqtt bridge node (esp32) using painlessmesh library, this node is the root device for the esp32 wifi mesh network and at the same time it's connected to the wifi network which contains the mosquitto mqtt broker, in other words it's connected to 2 wifi networks at the same time (esp32 wifi mesh and mosquitto wifi), the mqtt bridge node will receive command from mosquitto topic and send it to the corresponding esp32 node, then it passes back the acknowledge from esp32 and publish it on the same mqtt topic general terms: ⦁ people whom are wants to participate on this project are required to proof the experience on the relevant fields (esp32, mqtt and esp32 wifi mesh) , for example links to previous work, videos, sample codes ⦁ code is required to be clean and well documented, comment are required to illustrate every section and function of the code ⦁ variable names used in the code are required to be illustrative and describes its functionality ⦁ error handling should be in mind when designing the code, for example (failing to connect to wifi network, failing to connect to mqtt broker, failing the subscribe to topic or publish, fialing to send to esp32 node in the mesh, failing to get acknowledge from esp32, and so on) ⦁ candidate is free to ask any questions so that requirements are clear in his mind ⦁ once agreed, selected cadidate needs to provide video for his implementation shows the system working with different components, candidate may use mosquitto_sub and mosquitto_pub in place of the mobile app ⦁ if the video is ok and show the system working fine, candidate to send the mqtt bridge code so that i will test and check it working fine ⦁ if the code is working fine in my environment, 75% of the agreed money will be released, 25% will be released after 1 week (during this period code will be tested in different scenarios to check there is no issues and there is no need for any fixes or modifications) ⦁ please don't waste my time by using code already on the net ⦁ environment used in this project is arduino ide classic (1.8.19) ⦁ budget 70$
