HL7800-M Power consumption at eDRX with TCP/TLS

Dear all,

I want to solve 2 problems that will be happen using TCP/TLS and eDRX.
TCP/TLS connection works fine before enter eDRX mode.

issue1: increase power consumption about 20mA when in eDRX mode after using TCP/TLS compare to using only TCP with eDRX mode .

issue2: TCP/TLS will not work after wakeup from eDRX mode.

These symptom are happen in firmware 4.4.6 and 4.4.17.
Unfortunately Ver 4.6.8 and 4.5.4 does not work fine, It does not make a connection to server.

If I don’t use TCP/TLS , it work well with eDRX mode. There is no problem after wake up form eDRX mode.

I want to use TCP/TLS with eDRX mode.
Please let me know ,Is there any solution ?
