Problems with MQTT connection since 18.12.2022

Hi,

I have been able to make a MQTT connection with hivemq broker example provided with mqtt-announce.js. For some reason the UI changed a day ago and ever since I have had problems with connecting the broker. I have booted many times but no connection is made. I don't know how to debug any further?

Hi,

I did once more did not help: Code states the same "not connected". I used BLE functionality here and it works. Anyway problem happens even with minimalistic mqtt code.

// Scan options

let scanOptions = {

duration_ms: BLE.Scanner.INFINITE_SCAN, // Scan indefinitely

active: false, // Use passive scanning

interval_ms: 150,

window_ms: 50,

};

// Scan callback

function scanCB(ev, res) {

if (ev !== BLE.Scanner.SCAN_RESULT) return;

// Get the address and signal strength of the beacon

let addr = res.addr;

let rssi = res.rssi;

// Publish the beacon data to the MQTT topic

//MQTT.publish("beacons", JSON.stringify({ addres: addr, signal: rssi }));

//print(addr);

}

// Start scanning

BLE.Scanner.Start(scanOptions, scanCB);

// Publish a message every 10 seconds to confirm that the code is running

function mqttWatchdog(){

let status = MQTT.isConnected();

if(status){

print("Running");

MQTT.publish("beacons", "Running", 0, true);

print("Running");

} else {

print("Not connected");

}

}

Timer.set(2000, true, mqttWatchdog);
