Dear Nordic,
We are developing the Cat M1 module base on the nRF9160 V1.2.0.
When we try to evaluate the current consumption in eDRX mode, we found our module even unable to enter eDRX.
But DUT has already negotiated PTW and eDRX cycle timer with the network, which can be verified by command:
AT+CEDRXRDP
+CEDRXRDP: 4,"0101","0101","0001"
OK
1. Cat M1 power consumption in eDRX mode
While if switch DUT to NBIoT mode, it could enter eDRX as expected.
2. NB-IoT power consumption in eDRX mode
What's the difference between NBIoT and CatM1 mode for eDRX?
Why DUT could enter eDRX in NBIoT mode but couldn't in CatM1 mode?
Thanks,
Zhen
