Timeout Issue in MQTTClient

architmuchhal12 commented 7 years ago

Hello,

I am using ESP32 Arduino with Adafruti FONA 808 to connect to the MQTT Server. I have modified the MQTTClient.ino accordingly.

I am using hardware serial at 115200 baud rate. The issue I am facing is the serial monitor which displays the reason for no connection as (-4) which is due to Timeout Value. I also tried increasing the timeout value in the library but with no success.

Please suggest me a solution! Thanks!

Init Code:

// Select your modem:
#define TINY_GSM_MODEM_SIM800
//#define TINY_GSM_MODEM_SIM900
//#define TINY_GSM_MODEM_A6
//#define TINY_GSM_MODEM_M590

#include <TinyGsmClient.h>
#include <PubSubClient.h>
#include "Adafruit_FONA.h"

// Default pins for Feather 32u4 FONA
#define FONA_RST 25
HardwareSerial fonaSerial(1);
Adafruit_FONA fona = Adafruit_FONA(FONA_RST);

// Your GPRS credentials
// Leave empty, if missing user or pass
const char apn[]  = "wholesale";
const char user[] = "0";
const char pass[] = "0";

TinyGsm modem(fonaSerial);
TinyGsmClient client(modem);
PubSubClient mqtt(client);

const char* broker = "***********";
const char* userName = "******";

FONA808 Initiliazation:

// Set FONA module baud rate
  fonaSerial.begin(115200, SERIAL_8N1, 33, 32);
  if (! fona.begin(fonaSerial)) {
    Serial.println(F("Couldn't find FONA"));
    while (1);
  }
  Serial.println(F("FONA is OK"));
  Serial.println(F("Found FONA808 (v2) "));
  delay(1000);

Serial Monitor Output:

P.S. I have gone through the existing issue #23 but did not get any solution. @holgerkoch and @vshymanskyy Can you help?

I'm not sure if you can use Adafruit_FONA with TinyGSM simultaneously. I think you should try using TinyGSM separately.

Hi! were you able to fix the problem? Im having a similar issue with my fona808 and arduino uno.
