7.2. Setup connections

7.2.1. CMD_CONNECT_REQ

This command tries to setup a connection to the Proteus-III, which is identified by the FS_BTMAC
used in the command. After the module prints a CMD_CONNECT_CNF to confirm that the request
was received, the indication message CMD_CONNECT_IND follows which determines whether the
connection request was accepted by the other device.
In case of enabled security features (see the setting RF_SecFlags ) a CMD_SECURITY_IND is
output in addition.
As soon as the connection setup has been completed and all services have been discovered
successfully a CMD_CHANNELOPEN_RSP is sent to the host. Now data may be sent using the
CMD_DATA_REQ .
