When Sleep Modes are enabled and IR (Sample Rate) is set, the module will remain awake until IT
samples have been collected.
IU (I/O Output Enable) command
AT Command: ATIU
Parameter Range:0 - 1
Parameter
0
1
Default Parameter Value:1
Minimum Firmware Version Required: 1.xA0
<I/O Settings> The IU command is used to disable/enable I/O UART output. When enabled (IU = 1),
received I/O line data packets are sent out the UART. The data is sent using an API frame regardless
of the current AP parameter value.
KY (AES Encryption Key) command
AT Command: ATKY
Parameter Range:0 - (any 16-byte value)
Default Parameter Value:0
Related Command: EE (Encryption Enable)
Minimum Firmware Version Required: v1.xA0
<Networking {Security}> The KY command is used to set the 128-bit AES (Advanced Encryption
Standard) key for encrypting/decrypting data. Once set, the key cannot be read out of the module by
any means.
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 KY by itself with no parameters, is invalid. All ATKY entries (valid or
not) are received with a returned 'OK'.
When queried, the system will return an 'OK' message and the value of the key will not be returned.
M0 (PWM0 Output Level) command
AT Command: ATM0
Parameter Range:0 - 0x03FF [steps]
Default Parameter Value:0
