BG95-M3 response time

I have got an issue with the communication response time when using BG95 M3.
The response time keeps changing, sometimes it even seems that the modele has entered the Power saving mode.
I need the response to be immediate.

The communication is the 2G network. Most messages are being sent irregularly, sometimes even 1 minute appart.
I tried to use the BG96 (using the same SW) and I had no problems.
Any help/idea would be much appreciated!
Thank you

Old FW BG95M3LAR02A03_01.003.01.003 has a bug.
I used the newest FW available BG95M3LAR02A03_01.005.01.005 and it’s working.

Can you explain bit more about your response time issue.

I am using MQTT and times, i have noticed message do get delayed and at times they are very fast.
