Attached is the test code for the tcp socket loop test. I have seen very high failures up to 26 failures out of 40 tcp socket create/connect attempts.

Code is attached. When the mosquitto server is shut down, the code loops, failing to connect via this call nxd_mqtt_client_login_set(&mqtt_client,MQTTNAME, STRLEN(MQTTNAME),MQTTPASS, STRLEN(MQTTPASS)). After failing, nxd_mqtt_client_disconnect(&mq...

In this loop the mqtt client is created, connected and as long as the mqtt server/broker is up, the client continues processing messages. But when the remote mqtt server/broker is manually shut down, and after the timeout expires, nxd_mqtt_client_c...

Just in case you haven't, test the functioning of the Azure client without the security so at the least you know that it works. I have successfully used the insecure mode of the NetX mqtt client code, but not the secure mode. However, I used TLS...

To clarify, I am asking about the UART connection that is used by the low level code to tx/rx data via the cell modem. Digging into the setup code for the driver I discovered that the MCU transmits data to Port A, GPIO4, and receives on Port C, GPI...

I don't recall getting mqtt client working on a stm32cubeide code base but I was able to get mqtt working with that board over wifi by using the Arduino code. Arduino libraries have the pubsub mqtt client, for example.

You can use the errors to guide you as to which includes you need to add. Go through the errors one by one, noting which file the errored code belongs to and then add the corresponding include file in the project properties, making sure to use the p...

I too am working with that discovery kit and getting familiar with the stm32cubeide can take awhile. I recommend first updating the ide to the latest version 1.9.I used X-CUBE-CELLULAR V7.0 , the latest, so I could use the Azure RTOS and related lib...

Performance of the AzureRTOS TCP sockets is mixed - I see high socket connection losses when running this TCP socket connect loop code. Do you have any suggestions to improve the socket handling of this code?

Anyone else working with the Azure RTOS NetX related code for the B-L462 Cell dev board? I've got the MQTT code working and I am debugging, attempting to improve connectivity.

What uart port connects to the modem on the B-L462E-CELL1 board?

Using the B-L462E cellular board with Azure NetX MQTT code to connect to, publish and subscribe topics on my own mosquitto server. How can I reconnect to MQTT after the server restarts?

Is there a socket allocation problem with X-CUBE-CELLULAR V7.0 using Azure RTOS and the STM32L462RE discovery kit Cellular IOT board?
