Gateway ESP32 DevKit V1 & MQTT & RF24 unable connect to WIFI

[eduardomarcos]

Hardware using:

• ESP32 DevKit V1
• RF24l01+ Both components works (previously checked with other programs)

I tried to install in the ESP32 the Gateway working in Ethernet mode. It works with current wiring (I followed the setup instructions)

But, when I try to configure it to work as an MQTT Gateway, it is unable to connect to Wifi. MQTT service is a mosquitto running locally (and it works good)

Serial Output: 1181 MCO:BGN:STP 1182 MCO:BGN:INIT OK,TSP=1 1190 GWT:TPC:CONNECTING... 2193 TSM:READY:NWD REQ 2198 ?TSF:MSG:SEND,0-0-255-255,s=255,c=3,t=20,pt=0,l=0,sg=0,ft=0,st=OK: 2207 GWT:TPC:CONNECTING... 3213 GWT:TPC:CONNECTING... 4220 GWT:TPC:CONNECTING... 5226 GWT:TPC:CONNECTING... 6232 GWT:TPC:CONNECTING... 7239 GWT:TPC:CONNECTING... 8246 GWT:TPC:CONNECTING... 9253 GWT:TPC:CONNECTING... 10260 GWT:TPC:CONNECTING... 11267 GWT:TPC:CONNECTING...

And it is always trying to connect :(

And the code that I'm using:

#define MY_DEBUG
#define MY_RADIO_RF24
#define MY_WIFI_SSID "ssid"
#define MY_WIFI_PASSWORD "pass"

#define MY_HOSTNAME "ESP32_GW"
#define MY_GATEWAY_MQTT_CLIENT
#define MY_GATEWAY_ESP32

#define MY_MQTT_PUBLISH_TOPIC_PREFIX "mygateway1-out"
#define MY_MQTT_SUBSCRIBE_TOPIC_PREFIX "mygateway1-in"
#define MY_MQTT_CLIENT_ID "mysensors-1"
#define MY_MQTT_USER "mosquitto"
#define MY_MQTT_PASSWORD "mosquitto"

// MQTT broker ip address.
#define MY_CONTROLLER_IP_ADDRESS 127, 0, 0, 1
// The MQTT broker port to to open
#define MY_PORT 8883

#include <MySensors.h>

void setup()
{

}

void presentation()
{
  // Present locally attached sensors here
}

void loop()
{
  // Send locally attached sensors data here
}

I tried different configurations and I always get the same result. Not possible to connect (But Ethernet Gateway mode with same hardware wiring works)

Any idea? Maybe I'm missing something?

Thanks in advance!

Well, after continuing with some research, I found out a two things.

1. I do not know how I was thinking about connecting to a localhost MQTT server from the ESP32... Silly me! So I changed the MQTT server to a reachable one, that also works.

2. I force the WiFi connection in the setup function. And it also worked. After doing that, I could connect to WiFi, and the rest of the configuration was successful, brilliant.

The output that I got:

1183 MCO:BGN:STP Force WiFi Connection

[Connecting] [-----------[IP address: 192.168.1.38] 6689 MCO:BGN:INIT OK,TSP=1 6694 GWT:TPC:IP=192.168.1.38 6698 GWT:RMQ:CONNECTING... 7197 GWT:RMQ:OK 7199 GWT:TPS:TOPIC=mygateway1-out/0/255/0/0/18,MSG SENT 7209 TSM:READY:NWD REQ 7214 ?TSF:MSG:SEND,0-0-255-255,s=255,c=3,t=20,pt=0,l=0,sg=0,ft=0,st=OK:

And the code that I added:

void setup()
{
  Serial.begin(115200);
  Serial.println("Force WiFi Connection");
  WiFi.begin(MY_WIFI_SSID, MY_WIFI_PASSWORD);
    Serial.print("\n[Connecting] [");
    while (WiFi.status() != WL_CONNECTED)
    {
        delay(500);
        Serial.print("-");
    }

    Serial.print("[IP address: ");
    Serial.print(WiFi.localIP());
    Serial.print("]\n");

}

When I added the timeout to 3 seconds it works.

bool gatewayTransportConnect(void)
{
#if defined(MY_GATEWAY_ESP8266) || defined(MY_GATEWAY_ESP32)
	if (WiFi.status() != WL_CONNECTED) {
		GATEWAY_DEBUG(PSTR("GWT:TPC:CONNECTING...\n"));
		delay(3000); // Changed from delay(1000);
		return false;
	}
	GATEWAY_DEBUG(PSTR("GWT:TPC:IP=%s\n"), WiFi.localIP().toString().c_str());

Should I create a pull request with this change?

I also have same ESP32 DevKit V1 and I had same problem... I added the timeout to 3 in the gatewayTransportConnect and it's work. All this if I use the official release. But if I use the DEV release VER=2.4.0-alpha is not work... it give me error:

Rebooting...

Thanks all Denis
