It seems like AT!SCACT fails in your case. It should look like my example below. Verify that the APN is correct and that you are registered in the network.
at+creg?
+CREG: 0,1
OK
at+cops?
+COPS: 1,0,"3 3",7
OK
at+cgdcont?
+CGDCONT: 1,"IP","data.tre.se","0.0.0.0",0,0
+CGDCONT: 2,"IP","data.tre.se","0.0.0.0",0,0
OK
at!scact?
!SCACT: 1,0
!SCACT: 2,0
OK
at!scact=1,1
OK
at!scact?
!SCACT: 1,1
!SCACT: 2,0
OKAfter running AT!SCACT=1,1 I use “sude dhclient eth2” in the host. eth2 is the first port enumerated on the MC7304. After that I can see that the interface get an IP using ifconfig. I have no experience with dhcp6c.
It is supported. Take a look in the build/bin of that package. As you can see there is a binary of the SDK for both MIPS and MIPSEL(little endian).
It seems like the sample applications are only pre built for MIPSEL. But it ise easy to build the sample applications. Just run make in path of any of the sample apps.
