mqtt | PHP7 MQTT client with * * full * * protocol support

Update the library of firebase:

implementation platform('com.google.firebase:firebase-bom:29.1.0') implementation 'com.google.firebase:firebase-messaging'

and remove implementation 'com.google.firebase:firebase-messaging:23.0.0'

I am getting the following response which seems to indicate an error in the mysql query

That's not an error in your MySQL query. It's a null reference error because you're trying to use result outside the callback.

Changing your code to this will work:

As per the comments the issue was with the configuration of the MqttNet Broker.

The setting MaxPendingMessagesPerClient defaults to 250 meaning that when there are 250 messages awaiting delivery for a specific client, and another message arrives, the first message in the queue will be dropped.

Your application is sending messages faster than the receiver can process them so the queue builds quickly and messages are lost. The last 250 messages arrive without issue because nothing new is being sent (so the broker has no need to drop further messages).

To fix this you can use WithMaxPendingMessagesPerClient e.g.

This is because you are using V2 of chart.js while using V3 syntax. For V2 all x axes scales are in an array calles xAxes and not their own object.

For the full docs you can see them here

Live example:

Not only do you have multiple calls, you also have a memory leak. The event subscription will prevent the Monitor object to be collected.

Possible solution

Upgrade google analytics to firebase analaytics. Hope it'll solve your problems.Also upgrade all the library what're you using.

For me below solutions solve the problem.

Add PendingIntent.FLAG_IMMUTABLE to your pending intents.

Here is an example -

PendingIntent pendingIntent = PendingIntent.getActivity(this, alarmID, notificationIntent, PendingIntent.FLAG_IMMUTABLE);

There can be a multitude of reasons why it does not work for you. Among them are:

• The host networking driver only works on Linux hosts, so if you use Docker for Mac, Docker for Windows or Docker Enterprise Edition it won't work.
• The port 2345 might be already in use on your machine, and the delve process might not be able to bind it.
• You might be using the wrong hostname when connecting to your session (your snippet shows 127.0.0.1 but it is commented out, and I don't know what IP it selects when one is not provided).

I am not sure why you are trying to use the host networking mode however, as it is normally useful for two main use-cases: it is more performant to use it when a docker container needs to bind a large range of ports (hundreds or thousands of ports), and can be convenient when running a Docker swarm as long as services do not have conflicting ports within the swarm.

It doesn't seem to me like any of those cases are related to the situation you describe, so even though that was not your original question, it is my recommendation that you look for other solutions to solve the problem which you attempted to solve by using host networking mode.

Solution!!

Since service is not executeable, instead of using service, i just executed mosquitto via mosquitto command.

If you look at the source of lepiaf\SerialPort you'll find it sets the stream in non blocking mode, however the read method does an infinite loop until it finds the separator. This means it will never return unless the separator is received, and depending on your configuration your script will be killed once the php max execution time is reached. Since the library is very simple the better option is to edit the read method adding a timeout parameter. Edit the file "lepiaf/SerialPort/SerialPort.php", scroll down to the read method (line 107) and change it as follows:
