8. You may want to perform a CMD_FACTORYRESET_REQ to restore default settings.

5.6.1.4. LescNumComp mode

In case of the "LescNumComp" mode, a pass key is displayed on peripheral and central
side. Both, the central and peripheral device must confirm that both keys are equal. Here
the Proteus-III uses a pass key that is generated by the LESC method (low energy secure
connection) when a connection is initiated. When using this method, the peripheral and central
device output the new generated pass key (see CMD_DISPLAY_PASSKEY_IND ) when a connection
setup has been initiated. Both, the central and peripheral device request their hosts to confirm
that both keys coincide (see CMD_NUMERIC_COMP_REQ ). If both devices confirmed the key, the
channel will be opened for data transmission. Otherwise, the connection will be rejected.
Example: Secured connection with security method "LescNumComp"
1. Power-up the modules and make their UARTs accessible by the host(s) (115200 Baud,
8n1). After the power-up or after reset the following sequence is sent from the module to
the host.
