Connect fail using BearSSL branch

[nopnop2002]

I flashed WiFiSpiESP BearSSL branch to WeMos D1 Mini(ESP12).

And I opened https://github.com/JiriBilek/WiFiSpi/tree/BearSSL/examples/ConnectWithWPA, edit ssid & pass, flashed to Arduino Uno.

And I connected D1 and UNO, Reset Uno.

But connection fail.

Do you have any help.

Could the buffer be too small?

The buffer should be ok, the messages can be of (almost) any length. But 'Bad CRC' could show bad SPI connection.
I am not sure if you need 5V/3V3 convertor, but I'd try to put it in the SPI bus. And I'd try to slow down the SPI speed in case of any interference.

[nopnop2002]

I'm sorry, I made a mistake on the UNO side.

wrong:
char ssid[] = "aterm-d5a4ee-g "; // your network SSID (name)

correct:
char ssid[] = "aterm-d5a4ee-g"; // your network SSID (name)

But I can't connect.
esp12 is correctly receiving the ssid and passphrase.
ssid: [aterm-d5a4ee-g]passphrase: [7530c4872b4f2] -> 7

• My code:

    WiFi.mode(WIFI_OFF);
    WiFi.mode(WIFI_STA); 
#if defined(ESPSPI_MONITOR)
        Serial.printf("ssid: [%s]", ssid);
        Serial.printf("passphrase: [%s]", passphrase);
#endif
    uint8_t status = WiFi.begin(ssid, passphrase);

I hope I understand the 'state' value well, then you are losing the connection.
The 'state: x->y' should write values from the following enum:

typedef enum {
    WL_NO_SHIELD        = 255,   // for compatibility with WiFi Shield library
    WL_IDLE_STATUS      = 0,
    WL_NO_SSID_AVAIL    = 1,
    WL_SCAN_COMPLETED   = 2,
    WL_CONNECTED        = 3,
    WL_CONNECT_FAILED   = 4,
    WL_CONNECTION_LOST  = 5,
    WL_DISCONNECTED     = 6
} wl_status_t;

Please try a sketch from Arduino/ESP8266 examples first in order to be sure there are no problems with your ESP8266 and it can connecti to the AP.
Also I'd recommend to turn off the ESPSPI_MONITOR debugging when you urgently don't need it as it may break the SPI communication. From what I've seen, I can tell the communication between the Arduino and the ESP is ok.

[nopnop2002]

I have changed some code in ConnectWithWAP:

  // attempt to connect to Wifi network:
#if 0
  while (status != WL_CONNECTED) {
    Serial.print("Attempting to connect to WPA SSID: ");
    Serial.println(ssid);
    // Connect to WPA/WPA2 network:
    status = WiFiSpi.begin(ssid, pass);

    // wait 10 seconds for connection:
    delay(10000);
  }
#else
  Serial.print("Attempting to connect to WPA SSID: ");
  Serial.println(ssid);
  // Connect to WPA/WPA2 network:
  status = WiFiSpi.begin(ssid, pass);
  while(1) {
    if ( WiFiSpi.status() == WL_CONNECTED) break;
    // wait 1 seconds for connection:
    delay(1000);
  }
#endif

It connected.

I pressed the UNO reset button several times.
I get this error sometime.

Since all GPIOs of ESP8266 are 5V tolerant, we don't need 5V/3V3 convertor.
It may be a problem with SPI Speed.

Hi, I tested ConnectWithWPA sketch on my device (STM32F103 + ESP8266) and got correct results (run several times to be sure it gives the same result for each run).
I admit, I am not using the recent version of Arduino/ESP8266, I fixed the commit c61b70de865531f62218541fa0f32715c153a449 (14 months old) but it should not matter.

I want to see your logs with _DEBUG_MESSAGES enabled.

It’s mine:

Edit: My SPI bus speed is 4 MHz.

Edit: My SPI bus speed is 4 MHz.

Where is SPI SPEED defined in the header file?

Maybe in my environment the last a0 message cannot be received by UNO.

So UNO demands a reconnection.

And I have one more question.

Why are so many GET_CONN_STATUS_CMD issued?

The function WiFiSpi.init(); has parameter max_speed.

Edit: Connecting to my AP takes a time, so that more GET_CONN_STATUS_CMD commands are not unusual.

The waiting loop for connecting is here:

uint8_t WiFiSpiClass::begin(const char* ssid)
{
	uint8_t status = WL_IDLE_STATUS;
	uint8_t attempts = WL_MAX_ATTEMPT_CONNECTION;

    if (WiFiSpiDrv::wifiSetNetwork(ssid, strlen(ssid)) != WL_FAILURE)
    {
	    do
	    {
		    delay(WL_DELAY_START_CONNECTION);
		    status = WiFiSpiDrv::getConnectionStatus();
	    }
	    while (((status == WL_IDLE_STATUS) || (status == WL_SCAN_COMPLETED) || (status == WL_DISCONNECTED)) && (--attempts > 0));
    } else
	    status = WL_CONNECT_FAILED;
   
    return status;
}

[nopnop2002]

If max_speed is not specified, UNO's SPI speed is probably 8Mhz.

If max_speed is specified, SPI.beginTransaction is executed.
But there is no SPI.endTransaction.

void WiFiSpiDrv::wifiDriverInit(uint8_t pin, uint32_t max_speed, SPIClass *in_spi)
{
    spi_obj = in_spi;
    spi_obj->begin();

    if (max_speed != 0)
        spi_obj->beginTransaction(SPISettings(max_speed, MSBFIRST, SPI_MODE0));
    
    espSpiProxy.begin(pin, spi_obj);
}

[JiriBilek]

It's rather old code of mine, I can't remember all details, but AFAIK the endTransaction is not that important, try to slow down the bus.
IMHO, the Arduino bus is 4 MHz as well, see:

class SPISettings {
public:
  SPISettings(uint32_t clock, uint8_t bitOrder, uint8_t dataMode) {
    if (__builtin_constant_p(clock)) {
      init_AlwaysInline(clock, bitOrder, dataMode);
    } else {
      init_MightInline(clock, bitOrder, dataMode);
    }
  }
  SPISettings() {
    init_AlwaysInline(4000000, MSBFIRST, SPI_MODE0);
  }

[nopnop2002]

For libraries that support SPI with transactions, SPI.begin() defines SPI_HAS_TRANSACTION.

{
    spi_obj = in_spi;
    spi_obj->begin();
#if defined(SPI_HAS_TRANSACTION)
  spi_obj->beginTransaction(SPISettings(max_speed, MSBFIRST, SPI_MODE0));
#endif

#if 0
    if (max_speed != 0)
        spi_obj->beginTransaction(SPISettings(max_speed, MSBFIRST, SPI_MODE0));
#endif    
    espSpiProxy.begin(pin, spi_obj);
}

Perhaps STM32's SPI LIBRARY may automatically issue endTransaction ().

[JiriBilek]

I believe, beginTransaction is for us useful only in the two lines (AVR):

SPCR = settings.spcr;
SPSR = settings.spsr;

The SPI transaction in an Arduino construction, there no such term in SPI bus definition.
