Connecting to mqtt broker... (ArduinoOS | LininoIO chaos_calmer 2.0)

Official Hardware Classic Yún
1

Hi, I am trying the Arduino Cloud and uploaded the sample sketch for a simple thing with a simple CloudLedStatus.

At very first, I was using 1.5.3 images.

Following https://www.arduino.cc/en/Tutorial/YunSysupgrade bricked the Yún

Yún recovered using https://www.arduino.cc/en/Tutorial/YunUBootReflash.

U-Boot 1.1.5-linino-gc0f42dd0 (Jul 9 2016 - 12:23:30)

Booting image at 9fea0000 ...

Image Name: MIPS OpenWrt Linux-3.18.11
Created: 2016-07-09 14:30:02 UTC
Image Type: MIPS Linux Kernel Image (lzma compressed)
Data Size: 1280860 Bytes = 1.2 MB
Load Address: 80060000
Entry Point: 80060000
Verifying Checksum at 0x9fea0040 ...OK
Uncompressing Kernel Image ... OK
No initrd
...

...

Then, load again sample sketch (attached on this post, without credentials) with a lot of "Serial.println()" for debugging, and still unable to connect mqtt broker...

Connecting to mqtt broker...

I really appreciate your advice.

Best regards.

P.S.

I had the same experience, but haven't resolved it yet.

The library seems to call mqtt.arduino.cc on poll

/// Configurations
#define SERVER_DOMAIN "mqtt.arduino.cc"
#define SERVER_PORT 8883
#define PROPERTIES_MAX 10


void ArduinoCloudThing::poll() {
while (!client->isConnected()){
if (cloud_debug) {
CLOUD_DEBUG_STREAM.println("Connecting to mqtt broker...");
}
while (!connect()){
delay(1000);
}
if (cloud_debug) {
CLOUD_DEBUG_STREAM.println("Connected");
}
mqttSubscribe();
}
if(!network.connected() && client->isConnected()) {
client->disconnect();
}
client->yield();
}
