The following flow charts will give an example for the different SSP authentication methods
“just works” and “passkey entry” within an incoming call request from an iPhone (or other
compatible iOS device) using Telit’s Terminal I/O Utility app to the S42/Central
(see also the connection example in chapter 3.1.2).
The “
Target Application
” part will simulate the device at the end (DTE) which communicates
to the S42/Central with configuration commands.
The interesting part of the bonding procedure is placed between the yellow boxes “
Start of
bonding procedure
” and “
End of bonding procedure
”.
All serial commands between the “
Target Application
” and the “
S42
” out of the
bonding procedure are used for further configuration of LE Security.
The configuration commands and responses within the flow charts are described in the
S42/Central AT Command Reference
.
