Yes, here is a log that shows psm works good without KCELLMEAS=1,10. I think the problem may not be the KCELLMEAS here,
As you said here, something is waking up the module, and automatically I am getting kcellmeas after 10secs as it is expected according to the reference guides. I think the psm loop issue occurs because of my software, that doesn’t expect that much quick kcellmeas. The problem is that the first wake up by something we dont know ATM.

I cant try this one. But I tried something maybe similar to this. I used +KCELLMEAS=0 instead. I ran +KCELLMEAS=0 every 3 secs for 2mins, though, the device never got valid kcellmeas until I started UDP/TCP comms.
My application needs to send data whenever it wakes up. So, thats why I only set kcellmeas=1,10 on time during modem driver initialization.
