LTE BVLOS setup

NeoRedPill

Hello,

We are looking for a R&D setup based on development drone Starling 2 (MRB-D0012-4-V4-C28-M3-T8-K3) with VOXL 2 Cellular add-on (MDK-M0130-3-03).
We expect to use the setup with a LTE BVLOS connectivity and analyze the traffic and behavior from the embedded modem (at PHY/MAC layer).
We pass thought the didactic material (bootcamp, specifications and code) but remains some questions:

Is the hardware selection make sense for our application?
Is the VOXL 2 already manage the BVLOS connectivity?
Even modem configurability via QMI, we need to collect L1 information from the 4G modem. This is usually possible through a diagnostic port (DM/DIAG) with a Qualcomm's QXDM tool. It this port is available from the add-on board? Or available from VOXL's USB port?

Thanks

Stephane
