    Requiero realizar la conexión automática entre dos ESP-01. Funciones deseadas: - Pulsar botón (transmisor-maestro), conexión automática entre el transmisor y el receptor - Mantener conectividad estable al estar cerca (1 o 2 metros) - Enviar a dormir el dispositivo ESP-01 (transmisor-maestro) para ahorro de batería. (siempre deben estar conectados) - Encender un led (receptor-esclavo) cuando se pierda la conexión (solo se debe perder la conexión si los ESP-01 están fuera de rango en metros)

    esp32 wifi mqtt reconnect 6 días left
    VERIFICADO

    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.

    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.

I made a pdf to better explain how the app should be. The images are taken from existing App like Magic Home or Magic Hue. The use should be quite the same... I'm from Italy so we will need to understand how to test the App without having the light.
