ncs v3.0.0 nRF9160 SMS PSM eDRX

[peter.min]

Hi,

1.As shown in the following PSM eDRX figure, during the red period, how will the text messages sent to nRF9160 be processed? Will the nRF9160 module receive them in the next green period?
2. Why can't customers receive SMS messages during the red period but not during the green period when they are tested with China Mobile's CMNBIOT?

Kind regards,
Peter.Min

Hi, here came some more information

1, Tested at NCS 2.7. For both mdmfw 1.2.5 and mdmfw 1.3.5,  it shows same results.

2, Similarly, while no edrx/ no psm, if SMS was sent druing cfun=0, we still could not receive SMS druing cfun=1. However, if we sent one more SMS druing cfun=1, then we can receive all previously missed SMSs. Please refer to below
