The following sections illustrate the types of frames encountered while using the API.
Note The following information is missing or incorrect in the API graphics:
Transmit option 0x08 is not supported
The following information is not shown in the API graphics:
The 64-bit destination address can be set to 0 as an alternate address for the coordinator.
The maximum broadcast radius is 32.
You can use the NO command to include the DD parameter in the Node Identification
Indicator (0x95).

Modem Status

API Identifier Value: (0x8A)
RF module status messages are sent from the module in response to specific conditions.
Figure 35: Modem status frames

AT command

API Identifier Value: 0x08
Allows for module parameter registers to be queried or set.
Figure 36: AT Command frames.
Identifies the UART data frame for the host to
correlate with a subsequent ACK (acknowledgement).
If set to ' 0 ', no response is sent.
