3. Configuration
3.1 Operation Mode
Several Bluetooth settings must be made on the WCS-232 prior to setting up the serial port. The user should
understand the following Bluetooth connection modes:
-The Bluetooth device works as a master or slave. The master device attempts to connect to another Bluetooth
device, while the slave device waits for access. Bluetooth connections are always paired with the master and slave.
-Slave has two modes: Inquiry Scan and Page Scan. The Inquiry scan mode waits for an inquiry packet from another
Bluetooth device, and the Page scan mode waits for a connection packet.
-All Bluetooth devices have unique 12-digit address called BD(Bluetooth Device) address.
※ WCS-232 is released as a basic 1 set in a 1:1 paired state.
WCS-232 operates in four modes: Each mode is indicated by the LED described in the following sections.
Mode
Description
Mode 0
The mode used to control WCS-232 directly with the AT command.
After power on or software initialization, it waits for AT command input without any response,
neither master nor slave is assigned. The extended AT commands set provided allow WCS-
232 to perform functions such as search and connection. If you want to change the settings of
WCS-232, it must be in MODE 0 state.
Mode 1
The mode that attempts to connect to the last connected Bluetooth device.
It becomes the master device and will attempt to connect to the Bluetooth device which has
the last successfully connected BD address. For initial use or after hardware initialization,
Mode 1 is meaningless as there is no BD address memory of the last connected Bluetooth
device, and mode does not switch to Mode 1 from other modes. The change to Mode 1 is
made after a successful connection to a specific Bluetooth device that which was tried to
connect to in Mode 1. Once switched to Mode 1, it only tries to connect to the Bluetooth device
which has DB address memory according to powering off and or software initialization. WCS-
232 set to Mode 1 is not detected or connected by another Bluetooth device.
Mode 2
The mode that waits for a connection from the last connected Bluetooth device.
It becomes the slave device and will wait a connection from the Bluetooth device which has
the last successfully connected BD address. Like Mode 1, if there is no BD address memory,
the mode cannot be switched to Mode 2. Once switched to Mode 2, it only waits and allow the
connection from the Bluetooth device which has BD address memory according to powering
off and off or software initialization. The WCS-232 set to Mode 2 cannot be detected by
another Bluetooth devices and only connected to a Bluetooth device with BD address memory.
Mode 3
The mode waiting for connections from other Bluetooth devices.
