AT commands
Serial interfacing commands
The following AT commands are serial interfacing commands.
AO (API Options)
The API data frame output format for RF packets received. This parameter applies to both the
UART and SPI interfaces.
Use AO to enable different API output frames.
Parameter range
0 - 2
Parameter
Description
0
API Rx Indicator - 0x90, this is for standard data frames.
1
API Explicit Rx Indicator - 0x91, this is for Explicit Addressing data frames.
2
XTend DigiMesh API Rx Indicator - 0x80
Default
2
AP (API Enable)
Set or read the API mode setting. The device can format the RF packets it receives into API frames
and send them out the serial port.
When you enable API, you must format the serial data as API frames because Transparent operating
mode is disabled.
Enables API Mode. The device ignores this command when using SPI. API mode 1 is always used.
Parameter range
0 - 2
Parameter Description
Transparent mode, API mode is off. All UART input and output is raw data and the
0
device uses the RO and RB parameters to delineate packets.
1
API Mode Without Escapes. The device packetizes all UART input and output data in API
format, without escape sequences.
2
API Mode With Escapes. The device is in API mode and inserts escaped sequences to
allow for control characters. The device passes XON (0x11), XOFF (0x13), Escape
(0x7D), and start delimiter 0x7E as data.
