Trouble Leaving PSM with BG95-M3

IoT Modules LPWA Module
1

I’m having some issues with canceling or removing myself from PSM.
Often times even after turning off PSM, my devices (tested only multiple BG95-M3) will re-enter PSM mode.
Often to get out of PSM mode, I have to spam AT+CPSMS=0 or AT+QPSMS=0 repeatedly.

Checking the status is not guaranteed either that I am fully out of PSM, as It appears that I can enter PSM again at any moment.

Any assistance would be greatly appreciated.

Hi @sstenzel

This is happened on QuecOpen solution or Standard solution? probably you called PSM API?
please help check this firstly.

Greetings,

I don’t know that I fully understand the question as I am unsure what QuecOpen is.
This is happening when just using PSM via AT commands with a BG95-M3. The above was run via a serial connection to the device.

Thanks,
