Brainboxes BL-819, BL-830 manual Advanced Settings, Device Address, Device Name, Discoverability

3.7. Advanced Settings

The Advanced Settings section contains a more detailed range of settings that are least likely to require modification for any particular scenario to work. Each field will be discussed further below.

When the Advanced Settings has been selected, an additional section appears in the left-hand section called Default Settings. Both sections can be expanded at the same time to enable the user to view the current settings and the default settings at the same time.

As each section is opened, the previously opened section will close to prevent information moving off the bottom of the screen and thus requiring the user to scroll down.

Whenever a setting is changed, the field changes colour to indicate that a change has been made but not applied. After making a selection select the “Apply” icon to apply the setting.

Device Address

This field shows the Bluetooth Address (BD_ADDR) of the local device. As each Bluetooth device must have its own unique address, this field cannot be edited or modified in any way.

Device Name

In scenario’s where more than 1 Adapter is to be used in the same geographical location (i.e. they are all in range of each other/the controlling device), it may be wise to change the name of each device so that human users can more easily identify each individual.

This field does not have a drop down list of options. You must select the field and edit the name to your requirements.

Memory constraints on the Adapter mean that you must ensure that your desired name is less than 30 characters. The Factory setting for the local device name is “Brainboxes RS232 Adapter ”.

Discoverability

Discoverability is a feature that allows any other Bluetooth device to find (or not find) your Bluetooth device. Just because a Bluetooth device is non-discoverable it doesn’t mean it’s not also connectable. Because a Bluetooth connection is made using only the device’s address, if an application already knows the address of a non- discoverable remote device, and it has already bonded (if appropriate) or knows the correct PIN number, then it can connect to that device. You may wish to set this option to help avoid confusion when many RS-232 Bluetooth Adapters exist in close proximity to each other.

This field has 2 options selected from the drop down list.

1)“On” is the default setting for the adapters. This setting will make the Adapter “viewable” by any other Bluetooth device.

2)Selecting “Off” immediately renders the adapter “non-discoverable”. No other Bluetooth devices will be able to see the Adapter when they perform a device discovery. However, in this mode, your adapter is still “connectable”.
