A problem with FB_OUTPUT_BISTABLE_MQTT function

[SzwedaM]

Hi all,
I have used this function in my project. It was working with no issue before. Unfortunately, I lost working this function after updating to the latest version. I am not able to control the relay from HA to my PLC now. I can see relay status changes on HA only - it looks like I have one way communication (from PLC to HA). I have tried to setup this function again using the new library with no success. I have copied Home Assistant samples to eliminate typing mistakes - still same problem.

What was changed in the last version?

Thank you for suggestions.
Regards
Mariusz

I guess, one thing you can double check all the MQTT paths.
It has changed in some version, I dont know which.
See my struggle #124, maybe it helps yours?

Thank you for your answer. As you suggested, the MQTTSubscribeTopic is the same for all my bistable relays. The name of the path is losing the last 4 characters as on the attached print screen. But why??

I am actually cleaning all these topics in a new PR #131
For now you can increase all these string lengths.

I have increased the string length to 60. It is working now.
Thank you for your assistance.
