The data will follow in the normal API format for DIO data.
The entire payload of the packet is encrypted using the key and the CRC is computed across the ciphertext. When encryption is enabled, each packet carries an additional 16 Bytes to convey the random CBC Initialization Vector (IV) to the receiver(s). The KY value may be “0” or any 128-bit value. Any other value, including entering ATKY by itself with no parameters, will cause an error.
MM (MAC Mode) Command AT Command: ATMM The MM command is used to set and Parameter Range:0 - 2 read the MAC Mode value. The Parameter Configuration MM command disables/enables the use of a Max-Stream header B&B Mode contained in the 802.15.4 RF 0 (802.15.4 + B&B packet. By default (MM = 0), B&B header) Mode is enabled and the module adds an extra header to the data 1 802.15.4 (no ACKs) portion of the 802.15.4 packet. 2 802.15.
receive three carriage returns at the end of the command. If no responses are received, the application should only receive one carriage return. When in API mode, the application should receive a frame (with no data) and status (set to „OK‟) at the end of the command. When the ND command packet is received, the remote sets up a random time delay (up to 2.
P0 (PWM0 Configuration) Command The P0 command is used to select/read the function for PWM0 (Pulse Width Modulation output 0). This command enables the option of translating incoming data to a PWM so that the output can be translated back into analog form. AT Command: ATP0_ The second character in the command is the number zero (“0”), not the letter “O”.
PR (Pull-up Resistor Enable) Command The PR command is used to set and read the bit field that is used to configure internal the pull-up resistor status for I/O lines. “1” specifies the pull-up resistor is enabled. “0” specifies no pull up. AT Command: ATPR Parameter Range: 0 - 0xFF Default Parameter Value: 0xFF _ (all pull-up resistors are enabled) Minimum Firmware Version Required: v1.
CSMA-CA stands for "Carrier Sense Multiple Access - Collision Avoidance". Unlike CSMA-CD (reacts to network transmissions after collisions have been detected), CSMA-CA acts to prevent data collisions before they occur. As soon as a module receives a packet that is to be transmitted, it checks if the channel is clear (no other module is transmitting). If the channel is clear, the packet is sent over-the-air.
received. The PWM output will also be set low at power-up until the first RF packet is received. A parameter value of 0xFF permanently enables the PWM output and it will always reflect the value of the last received RF packet. RR Command The RR command is used set/read the maximum number of retries the module will execute in addition to the 3 retries provided by the 802.15.4 MAC. AT Command: ATRR Parameter Range: 0 - 6 Default: 0 Minimum Firmware Version Required: 1.
Coordinator - If the „ReassignPANID‟ option is set on the Coordinator [refer to A2 parameter], the SD parameter determines the length of time the Coordinator will scan channels to locate existing PANs. If the „ReassignChannel‟ option is set, SD determines how long the Coordinator will perform an Energy Scan to determine which channel it will operate on. Scan Time is measured as ((# of Channels to Scan) * (2 ^ SD) * 15.36ms). The number of channels to scan is set by the SC command.
SM (Sleep Mode) Command The SM command is used to set and read Sleep Mode settings. By default, Sleep Modes are disabled (SM = 0) and the RF module remains in Idle/Receive Mode. When in this state, the module is constantly ready to respond to either serial or RF activity. AT Command: ATSM Parameter Range: 0 - 6 Parameter Configuration 0 Disabled 1 Pin Hibernate 2 Pin Doze 3 SM command options vary according to the networking system type.
ST (Time before Sleep) Command The ST command is used to set and read the period of inactivity (no serial or RF data is sent or received) before activating Sleep Mode.
<(Special)> The WR command is AT Command: ATWR used to write configurable parameters to the RF module's nonvolatile memory. Parameter values remain in the module's memory until overwritten by subsequent use of the WR Command. If changes are made without writing them to non-volatile memory, the module reverts back to previously saved parameters the next time the module is powered-on.
API Operation (AP parameter = 1) When this API mode is enabled (AP = 1), the UART data frame structure is defined as follows: UART Data Frame Structure: MSB = Most Significant Byte, LSB = Least Significant Byte API Operation - with Escape Characters (AP parameter = 2) When this API mode is enabled (AP = 2), the UART data frame structure is defined as follows: UART Data Frame Structure with escape control characters: MSB = Most Significant Byte, LSB = Least Significant Byte Escape characters.
To verify: Add all bytes (include checksum, but not the delimiter and length). If the checksum is correct, the sum will equal 0xFF. 3.4.2. API Types Frame data of the UART data frame forms an API-specific structure as follows: UART Data Frame & API specific Structure: The cmdID frame (API-identifier) indicates which API messages will be contained in the cmdData frame (Identifier-specific data). Refer to the sections that follow for more information regarding the supported API types.
AT Command API Identifier Value: 0x08 The “AT Command” API type allows for module parameters to be queried or set. When using this command ID, new parameter values are applied immediately. This includes any register set with the “AT Command - Queue Parameter Value” (0x09) API type. AT Command Frames Example: API frames when reading the DL parameter value of the module. Example: API frames when modifying the DL parameter value of the module.
AT Command Response API Identifier Value: 0x88 Response to previous command. In response to an AT Command message, the module will send an AT Command Response message. Some commands will send back multiple frames (for example, the ND (Node Discover) and AS (Active Scan) commands). These commands will end by sending a frame with a status of ATCMD_OK and no cmdData. AT Command Response Frames.
TX (Transmit) Status API Identifier Value: 0x89 When a TX Request is completed, the module sends a TX Status message. This message will indicate if the packet was transmitted successfully or if there was a failure. TX Status Frames NOTES: • “STATUS = 1” occurs when all retries are expired and no ACK is received. • If transmitter broadcasts (destination address = 0x000000000000FFFF), only “STATUS = 0 or 2” will be returned. • “STATUS = 3” occurs when Coordinator times out of an indirect transmission.
