Firebase connectivity Issue using enc28j60 module on esp32

[Ranajayy]

Hi im using the enc28j60 module to connect to firebase on esp32 instead of wifi, im using the , examples/ExternalClient/Ethernet examples to try and use ethernet to conenct to firebase but i keep getting the -4 error, i dont under stand what im doing wrong
below is the attached example code im using and the resposne:

CODE:

#include <FirebaseESP32.h>

// Provide the token generation process info.
#include <addons/TokenHelper.h>

// Provide the RTDB payload printing info and other helper functions.
#include <addons/RTDBHelper.h>

#include <EthernetENC.h>

// For the following credentials, see examples/Authentications/SignInAsUser/EmailPassword/EmailPassword.ino

/* 1. Define the API Key */
#define API_KEY "*********************"
#define DATABASE_URL "********************"
#define USER_EMAIL "u************"
#define USER_PASSWORD "********"

/* 4. Defined the Ethernet module connection */
#define WIZNET_RESET_PIN 26 // Connect W5500 Reset pin to GPIO 26 of ESP32
#define WIZNET_CS_PIN 5     // Connect W5500 CS pin to GPIO 5 of ESP32
#define WIZNET_MISO_PIN 19  // Connect W5500 MISO pin to GPIO 19 of ESP32
#define WIZNET_MOSI_PIN 23  // Connect W5500 MOSI pin to GPIO 23 of ESP32
#define WIZNET_SCLK_PIN 18  // Connect W5500 SCLK pin to GPIO 18 of ESP32

/* 5. Define MAC */
uint8_t Eth_MAC[] = {0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED};

/* 6. Define the static IP (Optional)
IPAddress localIP(192, 168, 1, 104);
IPAddress subnet(255, 255, 0, 0);
IPAddress gateway(192, 168, 1, 1);
IPAddress dnsServer(8, 8, 8, 8);
bool optional = false; // Use this static IP only no DHCP
Firebase_StaticIP staIP(localIP, subnet, gateway, dnsServer, optional);
*/

// Define Firebase Data object
FirebaseData stream;
FirebaseData fbdo;

FirebaseAuth auth;
FirebaseConfig config;

unsigned long sendDataPrevMillis = 0;

int count = 0;

volatile bool dataChanged = false;

EthernetClient eth1;

void streamCallback(StreamData data)

}

void loop()
{
}

and the output on the monitor is :

im stuck can some one please help me

[mobizt]

Why you post the Serial monitor that is not related to the code?

Please check what's wrong. Are you already compile and upload it.

[Ranajayy]

i compiled and upload the code that is given in example but it gives the above out put

[mobizt]

There is no Ethernet initialization in serial monitor, what you are doing?

[mobizt]

I recommend you should use this alternative method to allow library to request the connection and status checking via callback.
https://github.com/mobizt/Firebase-ESP32/blob/master/examples/ExternalClient/Generic/Basic/Basic.ino

[mobizt]

If you still use setEthernetClient method, the issue can be occurred in case ethernet link down.

[Ranajayy]

ok sir will try the alternative method and let you know the response as well thank you very much.

[mobizt]

You can update to v4.4.7 which Ethernet library and Class can be configurable.

Firebase-ESP32/examples/ExternalClient/Ethernet/Basic/Basic.ino

Lines 26 to 31 in f49c467

	#include <Ethernet.h>
	// For using other Ethernet library that works with other Ethernet module,
	// the following build flags or macros should be assigned in src/FirebaseFS.h or your CustomFirebaseFS.h.
	// FIREBASE_ETHERNET_MODULE_LIB and FIREBASE_ETHERNET_MODULE_CLASS
	// See src/FirebaseFS.h for detail.

Firebase-ESP32/src/FirebaseFS.h

Lines 178 to 188 in f49c467

	/** 🔖 Optional Build Options
	*
	* 🏷️ For external Ethernet module support.
	* - Should define both library name and class object name.
	* - FIREBASE_ETHERNET_MODULE_LIB is the Ethernet library name with extension (.h) and
	* should be inside "" or <> e.g. "Ethernet.h".
	* - FIREBASE_ETHERNET_MODULE_CLASS is the name of static object defined from class e.g. Ethernet.

ok sir ill update and try this configuration thank you for the updates.
