Adds two new MGMT Events: - MESH_DEVICE_FOUND - Returned when Mesh is enabled, and one of the requested AD Types is detected in an incoming Advertisement. - MESH_TX_COMPLETE - Reports that a prior requested transmission has completed and no longer consumes one of the available outbound slots. --- doc/mgmt-api.txt | 170 +++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 170 insertions(+) diff --git a/doc/mgmt-api.txt b/doc/mgmt-api.txt index ebe56afa4..2da89e2f3 100644 --- a/doc/mgmt-api.txt +++ b/doc/mgmt-api.txt @@ -332,6 +332,7 @@ Read Controller Information Command 15 Static Address 16 PHY Configuration 17 Wideband Speech + 18 Mesh Mode This command generates a Command Complete event on success or a Command Status event on failure. @@ -3858,6 +3859,128 @@ Add Advertisement Patterns Monitor With RSSI Threshold Command Invalid Parameters +Set Mesh Receiver Command +========================= + + Command Code: 0x0057 + Controller Index: + Command Parameters: Enable (1 Octets) + Window (2 Octets) + Period (2 Octets) + Num AD Types (1 Octets) + AD Types (variable) + + This command Enables or Disables Mesh Receiving.
