8.9 APP_AES_Enable
This parameter enables or disables the encryption.
Value Description
0x00
Encryption disabled
0x01 Encryption enabled
Table 6: Parameter APP_AES_ENABLE
For the encryption to work, a suitable AES-key with its relating address has to be assigned. Also
see the respective commands
CMD_SET_AES_KEY_REQ
,
CMD_CLR_AES_KEY_REQ
and
CMD_GET_AES_DEV_REQ
as well as chapter 10.
8.10 APP_WOR_PeriodH
This parameter contains the high byte for the length of the wake period in WOR operation.
8.11 APP_WOR_PeriodL
This parameter together with the previous parameter determines the length of the wake-up
period in ms.
8.12 APP_WOR_MultiplierH
This parameter together with the previous parameters determines the length of the wake-up
period in ms.
8.13 APP_WOR_MultiplierL
This parameter together with the previous parameters determines the length of the wake-up
period in ms According to the following formula:

Formula 1 Duration between wake-up times
After every wake-up timeout, the module wakes up and "listens" to check whether a preamble is
being received. If a preamble is being received, the module will look for a synchronisation
character.
A wake-up period T
WOR
of 0 is not permissible. Take care that none of the results of
Formula 1 are equal to 0!
8.14 APP_WOR_RX_Time
By means of this parameter, the user can set the duration for which the module is to be in RX
mode while in WOR operation. Up to 255 ms can be set. The minimum period should be at least
3 ms in order to ensure that the radio chip is ready. If a preamble is received during this period,
the module will remain in RX mode until a data set has been received or the preamble aborts.
