Do you support Bluetooth features like BLE Mesh, AoA (Angle of Arrival) and/or Angle of Departure (AoD) in your own AT Command Set Interface implementation?

No. There is no software support for BLE Mesh, AoA (Angle of Arrival) and Angle of Departure (AoD) in our current AT Command Set Interface implementation. Please feel free to build and develop your own BLE Mesh, AoA or AoD application in C by using the Bluetooth SDK and tools from Silicon Labs. In this case, as a starting point, we highly recommend the Simplicity Studio 5 IDE which offers a rich set / collection of example projects and templates.

Bluetooth Mesh is a wireless mesh topology and standard which enables many-to-many (m:m) device communication for an enormous number of local BLE devices. It supports large-scale node networks without the need of an ordinary BLE gateway infrastructure. Refer to https://www.lairdconnect.com/making-bluetooth-mesh-simple and https://www.bluetooth.com/learn-about-bluetooth/recent-enhancements/mesh for additional information.

Angle of Arrival (AoA) and Angle of Departure (AoD) are two concepts for location positioning and direction finding. Without going into too much detail and to keep things very simple: One of the two BLE devices must have at least two antennas or more, so that the data received from those antennas then can be used to identify the direction and angular position of the location where the Bluetooth signals come from.
