Hi,
trying to connect my Heltec Wifi Kit 8 to Cayenne Cloud using PlatfirmIO.
Device is connected to network but connecting to cayenne fails with “Network connect failed” message
Connecting to Cayenne via MQTT Client Software (MQTTfx) works fine so im sure all my configurations are ok (Username, password, client ID)
Any Ideas what i can check to get this work.
Which code you are using ??
//#define CAYENNE_DEBUG
#define CAYENNE_PRINT Serial
#include <CayenneMQTTESP8266.h>
// WiFi network info.
char ssid = “xxxx”;
char wifiPassword = “xxxxx”;
// Cayenne authentication info. This should be obtained from the Cayenne Dashboard.
char username = “xxxx”;
char password = “xxxx”;
char clientID = “xxxx”;
void MQTTsetup() {
Cayenne.begin(username,password,clientID);
}
void MQTTloop() {
Cayenne.loop();
Is hrltec wifi kit based on esp8266? Can you share any link on the device drivers docs.
yes im quite sure it is
Can you try this code Cayenne-MQTT-Arduino/ESP8266.ino at master · myDevicesIoT/Cayenne-MQTT-Arduino · GitHub
This one throws some errors. maybe u can give me a hint whats wrong

This issue is because the device is not listed in detect device list. Let me check what can be done.
the only difference from ur code to mine ist that u have 2 parameters more in begin function.
Why is there a failure then cause of missing board?
Cayenne.begin(username, password, clientID, ssid, wifiPassword);
Any ideas already?
Are you using platformio?
Yes I do
i am not sure if that is what producing the error, but is that board compatible with arduino IDE?
I already did a few other projects with this board… So I think it works
can you try the above code with the arduino IDE.
same here
can you try some example sketches and see if you can get data via TCP, like from Google or something.
If that works you might try a simple example MQTT sketch with some third party MQTT broker and see if that works. https://www.14core.com/pushing-topic-to-mqtt-with-esp32-esp8266/
Meanwhile i bougt an ESP32 and this works fine. So Thread can be closed.
Thank u for ur support.
That’s a better alternative.
