    Default Wifi proyect, better choice

    Hi list,

    I have to make a new PCB with a WIFI application. The application is simple, you just have to do three things: activate a relay, read a switch and measure the voltage of the battery. Simple.
    The status of this should be sent via a WIFI link to a remote location.

    I've been looking for some WIFI module:
    Microchip RN1810/RN1810 13..15
    MIcrochip ATWINC1510-MR210UB 7
    Espressif Systems ESP32-WROOM-32U 3.4
    WIRELESS-TAG WT8266-S1 4.45
    Murata LBWA1KL1FX-875 7..9
    SiliconLabs WF111-E-V1 8..9
    GainSpan Corporation 700-0084 13.. 17
    Wiznet WizFi310 13

    I think the ideal for this application is the ESP32-WROOM-32U module from Espressif Systems. It also has a microcontroller inside where you can load the program. The price is unbeatable.
    The problem lies in programming the micro of the ESP32 module. The official IDE works in C. There is also a manufacturer's Core for the Arduino development environment also.

    Either option is out of my abilities.
    Can someone shed some light on my darkness?

    Regards,
    Gamboa

    Maybe an ESP8266 board would be more suitable for you Gamboa.

    The really inexpensive modules have a standard AT serial interface and are full Wi-Fi. See here for a simple search I did on ebay:

    https://www.ebay.co.uk/itm/1-2-5-10P....c100005.m1851

    Also, here's a document for the standard AT command set for teh ESP8266 devices, but you'll need to check if the module you buy is the standard type. As can be seen from the PDF, the AT command set allows full access to Wi-Fi as either client or server.

    I've worked with the ESP32 devices using the GCC C++ compiler and they are good, but certainly not in the absolutely dreadful Arduino IDE! It is an abhorrent piece of software that actually shows the state of commonly used software these days. :-( I use the Eclipse IDE. It is a typical open source piece of nonsense where you have to jump through hoops to do something, which is typical of nerd software. i.e. Originally Linux stuff, but it is far, far better than the Arduino IDE. Unfortunately, MPLABX is another piece of open source, originally, Linux crap that has actually won awards! Why? It is slow, cumbersome and huge. With lots and lots of anomalies and devices missing etc.

    Thank you Les.

    I think it will be the best choice. I will choose a PIC under Proton connected to an ESP-WROOM-02U board. I need a UFL connector for an external antenna.

    ESP-WROOM-02U (https://www.mouser.es/ProductDetail/...XHmr1O9R8TQ%3D), 2.8
