mqtt | supported properties , please review | GraphQL library

I get this most common error message in shiny app. I am well aware of this error and have resolved it dozens of time. But this time I am stumped.

I have a bme688 sensor (from Pimoroni) connected to a RPI ZERO. I have the PAHO MQTT library so I can send the data to the broker.

If you see code below, in the very last line, I have a "time.sleep(5)". The code below works perfectly well. It takes the readings and sends them via the MQTT. The problem I have is that if I change the time from 5 seconds to 300 seconds (10 minutes), the MQTT does not seem to send the data. The RPI ZERO has the raspbian desktop installed so I ran it using Thonny to see if I get an error but everything works fine with the 300 second delay... but it does not send the data across to the broker.

Any thoughts?

I am working on MQTT connection establishment to the server. I need to send the data to the server in JSON schema format using AT Commands.
The module used in N58 Neoway module. Using AT Commands connection got established and for publishing data or subscribing data to/from the server, it should happen in JSON format.
The AT Command used is:

I need an help, I can't connect with the broker. I'm using MQTTNet library into my api project .net core this is my code:

Anyone know how to fix it ?

I am developing a MQTT app that takes some values through a board and bring it to a GUI. So I programmed also in C and in python (for the GUI). I have a problem with UTF-8 codification. In C I wrote it:

This might be me misunderstanding how Mongo works/new Go dev - but I'm not able to connect to my mongo instance from Go. When I connect to my Mongo instance using Studio 3T, I can connect just fine, browse the tables, etc. But If I try to connect using the Go module, it complains about not being able to find all the nodes. Is it necessary for it to be able to access all nodes? I thought the replica set itself was supposed to handle the replication?

For example, I have this Go code:

I'm working on a Iot project. In my case, user can schedule a actuator command to run on specified time.( say on 08/06/2021 at 08.05 AM). This will be stored in mongodb database as a date variable. My requirement is to send an MQTT publish message to actuator at that specified time. Note that, this scheduling is not like interval scheduling. Each schedule will run exactly one time. I also need to edit the scheduled date time.

There is one way to achieve this. Each time user schedule a command, I can run a setTimeout function. But this is not a good practice and editing the schedule is difficult. So please help me to find a optimal solution for this. Thanks in advance.
