Explicit Rx Indicator frame - 0x91
Description
When a device configured with explicit API Rx Indicator (AO (API Options) = 1) receives an RF packet, it
sends it out the serial interface using this message type.
Note If a Transmit Request frame - 0x10 is sent to a device with AO = 1, the receiving device receives
a 0x91 frame with the Source endpoint (SE), Destination endpoint (DE), and Cluster ID (CI) values, and
not the values set on the transmitting device in Transparent mode .
The Cluster ID and endpoints must be used to identify the type of transaction that occurred.
Format
The following table provides the contents of the frame. For details on frame structure, see API frame
format.
