AT Commands Over Bluetooth
It is possible to configure and control a remote Serial Port Adapter via Bluetooth
using AT commands.
Criteria for using AT commands over Bluetooth:
• A Bluetooth connection to the remote device (the device to configure) must ex-
ist. The Bluetooth connection can e.g. be established using another Serial Port
Adapter, a device with a PC-card/compact flash or a device with embedded
Bluetooth support.
•
The remote Serial Port Adapter must have turned on the support for configura-
tion over Bluetooth, for more information see the
“Write_Allow_Configuration_Over_Bluetooth” command.
•
Once the connection has been established, the escape sequence must be sent
over the Bluetooth connection to the remote Serial Port Adapter to move it
into AT mode.
o The same escape sequence rules apply to AT over Bluetooth as for AT
over cable, for more information see the section about Data Mode and
AT Mode.
o
Note that the same escape sequence is used for cable and Bluetooth.
Therefore, if you are using two Serial Port Adapters one of the Serial
Port Adapters must have its escape sequence changed using the ATS2
command. This is to keep the first Serial Port Adapter to enter AT
mode instead of the remote Serial Port Adapter.
