We’re using HL7800 FW: BHL78XX.220.127.116.11 with a NB network with a private APN and static IP-addresses.
When I configure the modem to use an eDRX cycle of 81.92s (AT+CEDRXS=1,5,5) I never get any data (indicated by +KUDP_DATA=1,[size]) when sending something to the UDP-server session (AT+KUDPCFG=1,1,53439,0,1) running on the 7800.
However if I instead configure the eDRX cycle to be 20.48s (AT+CEDRXS=1,5,2) everything work as intended.
Note that this change is the only thing that is different in the setups.
How can I get this working?
Do someone else have a similar problem?
