Bluetooth® features
.AT1 implements the following Bluetooth® protocols and profiles:
● L2CAP
● RFCOMM
● SDP
● Generic access profile (GAP)
● Serial port profile (SPP)
AT command
The embedded SPP can be used in two modes:
● SERVER MODE: This mode allows the module to be connected by other devices. In
this configuration the local module does not initiate a Bluetooth® SPP connection, but
simply exposes an SPP service that can be connected by other devices. In order to
expose an SPP service the AT+BTREGPORT must be used.
) ● CLIENT MODE: This mode is used to initiate an SPP connection to an SPP service
t(s exposed by a remote Bluetooth® device. To set-up an SPP Bluetooth® link the
c AT+BTCONNECT must be used.
u The two modes of operation are fully interoperable and the same module can be configured
rod simultaneously both as a CLIENT and SERVER device. The module only allows a single
Bluetooth® SPP connection to exist at the same time.
P When an active connection is present (GPIO1 high) the module is set as “Non-Connectable”
te and “Non-Discoverable”, to reduce affection of inquiry scan or connection establishment
le attempt.
so When no more connection is active the module reset its modes to those previously stored by
Obsolete Product(s) - Ob “+BTCMODE” and “+BTDMODE” commands.
