BLE Spy template

When the BLE Spy mode is selected, the SpringCore device listens for all the BLE devices that are broadcasting in the nearby, and transmits to the host their advertisement data.

In simple mode (LKL=0E), only the content of the advertisement frame is returned. In full mode (LKL=0F), the "scan response data" frame is returned as well (if the remote BLE device has one).

Data transmitted to the host

The SpringCore Smart Reader sends to the host:

  • The BT_ADDR of the remote BLE device in field TagUid,
  • It's advertisement frame in field TagData,
  • It's scan response data frame in field TagDetails (full mode only),
  • The Rssi of the last frame received.
