5.3 PEPS Operation

The PEPS functionality is tested using the base station hardware (ATSAMC21-XPRO/ATA5831-XPRO/ATA5291-XPRO or ATA5293-XPRO/LF antenna module or X-10013-002 antenna/ATA8352-XPRO) and the ATAB5702A fob board with ATA8352-XPRO board. The PEPS operation is commanded by the CARS PC application to send LF wake-up messages along with UWB messages to the fob, which, then, responds with information via the UHF and UWB link.
Note: UWB boards are not required for PEPS Operation.
