Thanks a lot for the information, Роман.

Hi fabiooo,
I don’t use AT commands, you can retrieve that info with ModuleInformation, more info in this section.

Do You use currently the AT commands?
Ho do you query that info?

Hi wdaum,
if I remember the modules aren’t compatible, they are based on different technologies and EByte has changed the cryptography systems in the various models.

Hi Ludophot,
install an antenna; if not, you use It and retry.

The other problem is that I think there is a memory leak. Try to add some checks on the free memory

  Serial.println(ESP.getFreeHeap());

I found this tutorial, I think It’s what you need

Serial/UART Firmware Upload

A second firmware upload method is to use serial (UART) upload, which works in much the same way as the standard way of uploading code to an Arduino. Like in the case of the Arduino serial upload this approach relies on a pre-uploaded bootloader. My understanding is that the Nucleo boards already have this bootloader in place.

UART to Nucleo connections

• Connect GND and 5V for power.
• Place a jumper between BOOT0 and VDD to select the serial upload mode.
• Connect PA9 to UART RX
• Connect PA10 to UART TX
• Power cycle to reset board and enter serial upload mode

Serial Uploader Tool

On Windows ST provide a tool for uploading firmware over serial called STM32-Flasher: http://www.st.com/en/development-tools/flasher-stm32.html

For Linux there is a neat command line tool called stm32flash available in the package manager: http://manpages.ubuntu.com/manpages/bionic/man1/stm32flash.1.html

It can be installed with the following apt-get install:

sudo apt-get install stm32flash

I compiled the Arduino example Blink for the Nucleo64 STM32F303 using the Arduino IDE and then fetched the compliled .bin file from the /tmp folder that Arduino creates.

I could then upload to the STM32F303 by running:

sudo stm32flash -b 115200 -w blink.ino.bin /dev/ttyUSB0 

Terminal output:

$ sudo stm32flash -b 115200 w Blink.ino.bin /dev/ttyUSB0
stm32flash 0.5

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.
Bye Renzo

[Renzo Mischianti]

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

[Renzo Mischianti]

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

[Renzo Mischianti]

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.

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.
