    I want an arduin esp32 code where it connects with wifi and sends data over mqtt. It will check the internet connecton, wifi connection and of any failure it would try to re-establish itself. We should not need to reboot the device from outside, it should get back online whenever the problem is solved. The machine may restart after a long time when it is needed ,but remember on any failure it should not keep rebooting.

    You must live in the Western Balkans, Eastern Europe, Latin America, or the Caucasus. I am seeking either a high school student or a university student to help me build an Internet of things (IoT) device using MicroPython on the ESP32. (ESP32 is a microcontroller just as Arduino is a microcontroller). Why don't you need any experience? I would rather work with someone who is inexperienced yet very intelligent, rather than someone who is experienced yet not very intelligent. I will ask you a question that you must answer correctly, to prove to me that you are very intelligent. You must be able to work for five days each week for one hour per day. You may choose the five days which are convenient for you. You may work at any hour of the day (or night) that you would like.

    HART pressure transmitters for configuration via a distributed control system (DCS) or HART communicator. HART pressure transmitters are compatible with the Highway Addressable Remote Transducer (HART) communication protocol which is the most popular standard used with smart field devices by the process control industry. HART functionality enables the transfer of pressure transmitter data via an AC digital signal which uses the 4-20mA analogue output signal as a carrier, thus eliminating the need for extra wires and connectors.

    The pcb design that i made has an small error and i need someone to help me figure out the issue. Its a combination of Arduino Nano MCP328P + MCP2515 CANBUS board but in a smaller size with lots of extra arduino nano stuff removed as i will not be needing it. MCP328P chip and FDTI chip do communicate with PC and all digital/analog in/outs work quite well so no issues there, however the MCP2515 part is not able to receive nor send CANBUS messages so i am guessing within this simple pcb design i made an error that i cannot figure what is.
