Hi Nezha,
I write a little article about that and when I do the test, I follow the pinout I retrieve from the STMicroelectronic core code.

I check your pin selection, and it seems to be ok.

#ifdef HAL_SPI_MODULE_ENABLED
WEAK const PinMap PinMap_SPI_MOSI[] = {
  {PA_7,      SPI1, STM_PIN_DATA(STM_MODE_AF_PP, GPIO_PULLUP, GPIO_AF5_SPI1)},
  {PA_12,     SPI1, STM_PIN_DATA(STM_MODE_AF_PP, GPIO_PULLUP, GPIO_AF5_SPI1)},
  {PB_5,      SPI1, STM_PIN_DATA(STM_MODE_AF_PP, GPIO_PULLUP, GPIO_AF5_SPI1)},
  {PB_5_ALT1, SPI3, STM_PIN_DATA(STM_MODE_AF_PP, GPIO_PULLUP, GPIO_AF6_SPI3)},
  {PB_15,     SPI2, STM_PIN_DATA(STM_MODE_AF_PP, GPIO_PULLUP, GPIO_AF5_SPI2)},
  {PC_3,      SPI2, STM_PIN_DATA(STM_MODE_AF_PP, GPIO_PULLUP, GPIO_AF5_SPI2)},
  {PC_12,     SPI3, STM_PIN_DATA(STM_MODE_AF_PP, GPIO_PULLUP, GPIO_AF6_SPI3)},
  {NC,        NP,   0}
};
#endif

#ifdef HAL_SPI_MODULE_ENABLED
WEAK const PinMap PinMap_SPI_MISO[] = {
  {PA_6,      SPI1, STM_PIN_DATA(STM_MODE_AF_PP, GPIO_PULLUP, GPIO_AF5_SPI1)},
  {PA_11,     SPI1, STM_PIN_DATA(STM_MODE_AF_PP, GPIO_PULLUP, GPIO_AF5_SPI1)},
  {PB_4,      SPI1, STM_PIN_DATA(STM_MODE_AF_PP, GPIO_PULLUP, GPIO_AF5_SPI1)},
  {PB_4_ALT1, SPI3, STM_PIN_DATA(STM_MODE_AF_PP, GPIO_PULLUP, GPIO_AF6_SPI3)},
  {PB_14,     SPI2, STM_PIN_DATA(STM_MODE_AF_PP, GPIO_PULLUP, GPIO_AF5_SPI2)},
  {PC_2,      SPI2, STM_PIN_DATA(STM_MODE_AF_PP, GPIO_PULLUP, GPIO_AF5_SPI2)},
  {PC_11,     SPI3, STM_PIN_DATA(STM_MODE_AF_PP, GPIO_PULLUP, GPIO_AF6_SPI3)},
  {NC,        NP,   0}
};
#endif

#ifdef HAL_SPI_MODULE_ENABLED
WEAK const PinMap PinMap_SPI_SCLK[] = {
  {PA_1,      SPI1, STM_PIN_DATA(STM_MODE_AF_PP, GPIO_PULLUP, GPIO_AF5_SPI1)},
  {PA_5,      SPI1, STM_PIN_DATA(STM_MODE_AF_PP, GPIO_PULLUP, GPIO_AF5_SPI1)},
  {PB_3,      SPI1, STM_PIN_DATA(STM_MODE_AF_PP, GPIO_PULLUP, GPIO_AF5_SPI1)},
  {PB_3_ALT1, SPI3, STM_PIN_DATA(STM_MODE_AF_PP, GPIO_PULLUP, GPIO_AF6_SPI3)},
  {PB_10,     SPI2, STM_PIN_DATA(STM_MODE_AF_PP, GPIO_PULLUP, GPIO_AF5_SPI2)},
  {PB_13,     SPI2, STM_PIN_DATA(STM_MODE_AF_PP, GPIO_PULLUP, GPIO_AF5_SPI2)},
  {PC_10,     SPI3, STM_PIN_DATA(STM_MODE_AF_PP, GPIO_PULLUP, GPIO_AF6_SPI3)},
  {NC,        NP,   0}
};
#endif

The SS isn’t so important but if you can try the default also

// SPI definitions
#ifndef PIN_SPI_SS
  #define PIN_SPI_SS            PA4
#endif
#ifndef PIN_SPI_SS1
  #define PIN_SPI_SS1           PA15
#endif
#ifndef PIN_SPI_SS2
  #define PIN_SPI_SS2           PB0
#endif
#ifndef PIN_SPI_SS3
  #define PIN_SPI_SS3           PNUM_NOT_DEFINED
#endif
#ifndef PIN_SPI_MOSI
  #define PIN_SPI_MOSI          PA7
#endif
#ifndef PIN_SPI_MISO
  #define PIN_SPI_MISO          PA6
#endif
#ifndef PIN_SPI_SCK
  #define PIN_SPI_SCK           PA1
#endif

In the code, you begin two times the spi interface, and I think It can generate some problems.
Try to use a configuration declaration like this

//    SD card attached to the secondary SPI as follows:
//        SS    = PB2;
//        MOSI  = PC3;
//        MISO  = PB15;
//        SCK   = PB10;

#define SD_CS_PIN PB12
static SPIClass mySPI2(PC2, PC3, PB10, SD_CS_PIN);
#define SD2_CONFIG SdSpiConfig(SD_CS_PIN, DEDICATED_SPI, SD_SCK_MHZ(18), &mySPI2)

then only one begin.

  // we'll use the initialization code from the utility libraries
  // since we're just testing if the card is working!
  if (!SD.begin(SD2_CONFIG)) {
  // if (!SD.begin(SD_CS_PIN)) {
    Serial.println("initialization failed. Things to check:");
    Serial.println("* is a card inserted?");
    Serial.println("* is your wiring correct?");
    Serial.println("* did you change the chipSelect pin to match your shield or module?");
    while (1);
  } else {
    Serial.println("Wiring is correct and a card is present.");
  }

But check the STM32duino core can change the pin.

Try to use also the example I wrote and tested for the Arduino environment.

Thanks Mark,
I fixed It.
Thanks again Renzo

Hi,
I share It on PCBWay, not directly Gerber but you can order from PCBWay at the cost of the PCB.

In the master, you have a Relay with 3 exit
NO (Normally open) – COM (Input) – NC (Normally close)
if you put in COM 100v you can use NO e NC to activate an external SSR.

I think It’s your need.

Hi John,
In my farm I using a small pump with high prevalence (70m),

and it work without problem with the 200w panel I add a charging regulator to send 12v-like specs

The flow is less than the home water tap, but on a sunny day, fill the 1000l tank.

If you follow the indication of the Tank project, you can connect the Master that have two voltage regulator and a batter input connector that can be powered directly from 12v.

The client has the panel input and a voltage regulator with a rechargeable lithium battery and after it functions It goes into deep sleep.

This system I think can cover your expectations.

Hi DR-DNK,
I check the library and it works for me. Try to check your environment.

Hi gjb,
I wrote a paragraph on how to get RSSI here.

Hi rs77can,
I think there is the possibility that the webserver and email need a good quantity of RAM.
What are the specs of the MCU you use?

Hi,
I retest SdFat2 and standard SD, and works correctly.
Check if you have some issues in the importing library at compile time.

Hi Jon,
I think that there is no response from the firmware, probably the management is different and It can’t work.

Hi Edge,
with some limitation, you can transmit the message, but you must decrypt It I think work only transparent transmission.

https://blog.zesanglier.fr/2023/02/11/communiquer-entre-un-module-ebyte-e32-et-un-module-ra01-02-sx1278/

not a good idea for a production solution.

Hi jon,
you can check on your browser developer tools and go to WS –> Messages and check if the information arrives from the device.

Hi Giuseppe,
I don’t know which shield you buy, but you can go to the article on the relative shield and get the constructor.

Hi,
you can find more information on this article.

Hi,
It’s strange, che if you do something wrong with spiffs size.
The file is correct, you can have some other information about the management of gz file in this tutorial.

Web Server with esp8266 and esp32: byte array, gzipped pages and SPIFFS – 2
