as described on legato.io/legato-af/14_1/tools.html there should be SIM + APN + Data Commands, but on the AR7554 with the following firmware there is none:
Firmware Version: SWI9X15A_06.03.17.00 r23798 CNSHZ-AR-BUILD 2014/08/08 12:53:51
Bootloader Version: SWI9X15A_06.03.17.00 r23798 CNSHZ-AR-BUILD 2014/08/08 12:53:51
Linux Version: 3.4.36-yocto-standard #1 PREEMPT Fri Aug 8 07:16:46 EDT 2014
My assumption is that this is due to still under construction (early beta status) software.
Is there a newer firmware available for the AR7 board?
