Bluetooth features
.AT1 implements the following Bluetooth protocols and profiles:
●
●
●
●
●
The embedded SPP can be used in two modes:
●
●
The two modes of operation are fully interoperable and the same module can be configured
simultaneously both as a CLIENT and SERVER device. The module only allows a single
Bluetooth SPP connection to exist at the same time.
When an active connection is present (GPIO1 high) the module is set as “Non-Connectable”
and “Non-Discoverable”, to reduce affection of inquiry scan or connection entabishment
attempt.
When no more connection is active the module reset its modes to those previously stored by
“+BTCMODE” and “+BTDMODE” commands.

Generic Access Profile (GAP)
Serial Port Profile (SPP)
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
exposed by a remote Bluetooth device. To set-up an SPP Bluetooth link the
AT+BTCONNECT must be used.
