Message is not publishing to ESP8266 from IBM Bluemix

I have programmed to my ESP8266 and subscribed one topic to keep listening messages. This is my graphical view of injecting message to IBM Iot node.

This is my settings of inject view

This is my settings of IBM Iot node.

Here are my logs at Serial Monitor, it is connected and subscribed to cmd channel

So far so good, When I am trying to inject a message to my IBM Iot node then it is not publishing a message, as it is not reaching on serial monitor and no log on debug view. here you can see

Here is source code:

#include <ESP8266WiFi.h>
#include <PubSubClient.h> // https://github.com/knolleary/pubsubclient/releases/tag/v2.3

const char* ssid = "shiv";
const char* password = "manmohan@12345";

#define ORG "2kafk4"
#define DEVICE_TYPE "ESP8266"
#define DEVICE_ID "5CCF7FEED6F0"
#define TOKEN "opKF7v3@8jRM*mGkb_"

char server[] = ORG ".messaging.internetofthings.ibmcloud.com";
char topic[] = "iot-2/cmd/test/fmt/String";
char authMethod[] = "use-token-auth";
char token[] = TOKEN;
char clientId[] = "d:" ORG ":" DEVICE_TYPE ":" DEVICE_ID;

WiFiClient wifiClient;

void callback(char* topic, byte* payload, unsigned int payloadLength) {
  Serial.print("callback invoked for topic: "); Serial.println(topic);

  for (int i = 0; i < payloadLength; i++) {
    Serial.print((char)payload[i]);
  }
}
PubSubClient client(server, 1883, callback, wifiClient);

void setup() {
  Serial.begin(115200);
  Serial.println();
  wifiConnect();
  mqttConnect();
}

void loop() {
  if (!client.loop()) {
    mqttConnect();
  }
}

void wifiConnect() {
  Serial.print("Connecting to "); Serial.print(ssid);
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  Serial.print("nWiFi connected, IP address: "); Serial.println(WiFi.localIP());
}

void mqttConnect() {
  if (!client.connected()) {
    Serial.print("Reconnecting MQTT client to "); Serial.println(server);
    while (!client.connect(clientId, authMethod, token)) {
      Serial.print(".");
      delay(500);
    }
    initManagedDevice();
    Serial.println();
  }
}

void initManagedDevice() {
  if (client.subscribe(topic)) {
    Serial.println("subscribe to cmd OK");
  } else {
    Serial.println("subscribe to cmd FAILED");
  }
}

I tried to check cloud foundry logs using cf command, here it is https://pastebin.com/dfMaS1Gd

Can anyone hint me what I am doing wrong ? Thanks in advance.

Solution

  • Confirm the device type is correctly specified in your node configuration. Currently the screenshot show 0.16.2 which doesn't seem to match the device type you registered and what is specified in your code.
