How to manage timer values octet.
T3412ext value:
Bits 5 to 1 represent the binary coded timer value.
Bits 6 to 8 defines the timer value unit as follows:
Bits
8 7 6
0 0 0 value is incremented in multiples of 10 minutes
0 0 1 value is incremented in multiples of 1 hour
0 1 0 value is incremented in multiples of 10 hours
0 1 1 value is incremented in multiples of 2 seconds
1 0 0 value is incremented in multiples of 30 seconds
1 0 1 value is incremented in multiples of 1 minute
1 1 0 value is incremented in multiples of 320 hours
1 1 1 value indicates that the timer is deactivated.
Example: 10101100 -> 101 means values is incremented in multiples of 1
minute, 01100 means 12 -> the obtained value is 12 minutes
T3324 value:
Bits 5 to 1 represent the binary coded timer value.
Bits 6 to 8 defines the timer value unit for the GPRS timer as follows:
Bits
8 7 6
0 0 0 value is incremented in multiples of 2 seconds
0 0 1 value is incremented in multiples of 1 minute
0 1 0 value is incremented in multiples of decihours
1 1 1 value indicates that the timer is deactivated.
AT+CPSMS=1,,,"10101100","00100010"
OK
AT+CPSMS?
+CPSMS: 1,,,"10101100","00100010"
OK
It means that module requires to adopt the PSM for reducing its power consumption. If the
network supports PSM and accepts that the UE uses PSM with requested timers value,
module enters in PSM when the active timer expires (T3324=2 minutes) and stay in this mode
for ten minutes (T3412=12 minutes).
AT+CPSMS=0
OK
It means that PSM is set to disable, the module does not go to Power Saving Mode in any
case.
