Hi alltogether,
I am working on a project where I have to send MQTT Data every 10 Minutes via LTE (NB1).
I successfully activated PSM with AT+CPSMS=1,“00000001”,“00000101” (10min T3412), the network then assigned 120min T3412 to me - fair enough.
The module goes to PSM POWER DOWN as it should and it wakes up 120 Minutes later. But here are my questions:
-
I have to wake up the module every 10 min to send data. I can do this via the PWR Pin. Is this the right way? After I did send data, the module does not enter PSM again. How do I do that?
-
Does the wakeup every 10min affect the T3412 timer in any way?
-
When the module wakes up after the T3412 timer is expired (120min), it does not go into PSM again. What do I have to do to achieve this? AT+CPSMS still returns “active”. Executing the CPSMS command again does not have any effect.
Thank you and have a nice day!
