LabVIEW
POST to Kafka broker over TLS
Hi Community,
Details: LV2024 Q3 (64-bit) on Windows 11 using only LV native VI's.
Goal: Streaming messages to Kafka broker at 1 Hz from multiple test-rigs over secure TLS connection.
Situation: I setup the code for a secure TLS connection including required certificates, key and pw but I can't get it to work from LabVIEW. I don't receive any error but the messages are not appearing in Kafka. I increased all the timeouts to see if it is waiting somewhere but it runs in under a second. I do receive back 3 certificates in the 'server certificate chain' and it returns the 'bytes written'. The code is attached as a LV enriched PNG.
I verified the TCP connection is open via TNC in the command prompt.
Because it is already taking me quite some time I started in Python as well to validate my certificates and other TLS inputs, and my Python script works. I added the python code in a txt file attachment.
Is there anyone that notices an error in my LabVIEW code or maybe something I did different in Python?
Any help appreciated!
