3.3.29. AT#ENCALG - Set Encryption Algorithm
This command enables or disables the GSM and/or GPRS encryption algorithms
supported by the module.
AT#ENCALG=[<encGSM>][,<encGPRS]
Set command enables or disables the GSM and/or GPRS encryption
algorithms supported by the module.
Parameters:
The <encGSM> (one byte long) is a bit
mask where each bit, when set,
indicates the corresponding GSM
encryption algorithm
19. bit 0 = A5/1
20. bit 1 = A5/2
21. bit 2 = A5/3
22. bits 3 - 7 = reserved for future
use
no GSM encryption algorithm
sum of integers each representing a specific
GSM encryption algorithm: 1 – A5/1 2 – A5/2 4 –
A5/3
The <encGPRS> (one byte long) is a bit
mask where each bit, when set,
indicates the corresponding GPRS
encryption algorithm
23. bit 0 = GEA1
