Hi Nezha,
thanks for your feedback, not all makers work with STM32, if you’d like to share your projects we are happy to publish Them.

Hi jiangzhiyu233,
I executed your code and I replicated the issue. It seems that there are some problems when writing and reading at the same time.
I do a little fix, try It, and give me feedback.
Thanks Renzo

Hi jiangzhiyu233,
I retry the code and I don’t have that behavior, do you use the example provided in github??

Hi Nezha,
your problem. It’s very strange.
I think you can try to use a “first choice” SPI2 and “second choice” in coherence, like so:

PB15
PB14
PB10

and

PC3
PC2
PB13

After that test, you can try the official STMicroelectronics core to check if STM32duino.

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.

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.
Bye Renzo

[Renzo Mischianti]

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.
Bye Renzo

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

[Renzo Mischianti]

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.
Bye Renzo
