Hello,
I’m currently on a project that needs PSM working.
I have tested two devices which are R410M-02B and BG96 with same SIM card, but seems like only BG96 cannot enter PSM.
These are the AT commands I tired.

There is no PSM URC indication or QPSMTIMER URC after I left the device idle.
I have also tried at+qcfg=“psm/enter”,1 command but still cannot enter PSM.
I’m guessing maybe my firmware is outdated but I’m not really sure.
Any help will be appreciated!
Regards,
Kenny
