The PTR9611 ultra-low power Bluetooth 5 ready multiprotocol System on Module based

on the nRF52811 from Nordic Semiconductor. The module can support Bluetooth 5.1

by upgrading the protocol stack. The module with an ARM® Cortex™ M4 32 bit

processor, 192KB Flash/24KB RAM, Bluetooth 5.1 Direct Finding AOA/AOD support ，

provide a complete solution with no additional RF design, Bluetooth 5, allowing

faster time to market, while simplifying designs, reducing BOM costs, also reduce

the burden of Regulatory approvals to enter the world market. Making you more

quickly into the Bluetooth smart application and remove the worries.

Direction Finding enables positioning solutions to not only rely on received signal strength

indicator (RSSI), but also the actual direction of a signal. This improves accuracy

significantly and opens new possibilities for applications in this segment. There are two

types of methods for determining direction, angle of arrival (AoA), where the direction of

the received signal is calculated, and angle of departure (AoD), where the direction of the

transmitted signal is calculated. The Module is the perfect choice as a transmitter in both

the AoA or AoD scenarios, with its low power character and connectivity features.

ABLUE TECHNOLOGY /w ww .a bl ue te ch .c om The module integrated antenna requires a suitable ground plane to radiate effectively. The area under and extending out from the antenna portion of the module should be kept clear of copper and other metal. The module should be placed at the edge of the PCB with the antenna edge facing out. Reducing the ground plane will reduce the effective radiated power.
