3.2 Software Migration From xWR6843AoP ES1.0 to xWR6843AoP ES2.0

The changes described in this section are relevant for migrating the xWR6843AoP ES1.0 software based on the SDK 3.2.0.6 to xWR6843AoP ES2.0 and SDK 3.4.

Besides the addition of the Antenna on Package and a different antenna pattern, xWR6843AoP ES2.0 re-uses the same silicon. Hence software migration from xWR6843AoP ES1.0 to xWR6843AoP ES2.0 broadly includes the following steps in order:

  1. Initial migration of software to xWR6843ES2.0 (from MMWAVE-SDK 3.2.0.6 to MMWAVE-SDK 3.4). (Referred to below as Platform Software Updates)
  2. Angle of Arrival Processing updates for the updated antenna pattern on xWR6843AoP ES2.0. (Referred to below as AoA Software Updates)

Note:

MMWAVE-SDK 3.4.0 is the first baseline SDK release for xWR6843AoP ES2.0 device and the scope of migration notes provided in this section is limited to migrating to MMWAVE-SDK 3.4.0

When migrating existing xWR6843 AoP ES2.0 applications to SDK releases beyond MMWAVE SDK 3.4, you should follow the incremental migration instructions provided in the corresponding SDK release notes.
