Brainboxes BL-830, BL-819 manual Remote Configuration, Resetting the Product

5. Remote Configuration

One of the great features of Brainboxes RS-232 Bluetooth Adapters is the ability to be remotely configured. For example, a Bluetooth connection can be created from a second device and that second device can change the baud rate, local name or any of the settings of the adapter over the Bluetooth link.

This is achieved by the adapter presenting two services to connect to; one is the standard serial port service and the other is a remote configuration service. The latter is connected to, to enable the second device to access the adapter’s configuration menu using HyperTerminal and thus make any changes. Changes to port settings such as baud rate, parity or stop bits do not affect the port settings of the second devices’ HyperTerminal settings, so the adapter can be set to 115200, n, 1 and the HyperTerminal settings for the second device that is accessing the adapter’s menu remotely can be set to any settings i.e. 9600, e, 2.

Currently the remote configuration feature is not accessible from the main configuration utility application and HyperTerminal or some other suitable terminal application should be used.

Also, upgrading of the adapter cannot be achieved using remote configuration because as soon as the adapter starts to upgrade, the Bluetooth connection is lost and there is no longer a way of communicating to the adapter remotely.

To use remote configuration from adapter to adapter use the command line “remcfg=xxxx-xx-xxxxxx” where the x’s stand for the remote device’s Bluetooth address.

6. Resetting the Product

The adapter has a “reset button” located on the top of the case as shown in section 2.1 above. This button performs 2 different functions.

a)Resets Paired Devices.

A short press (less than 3 seconds) of the reset button causes any paired device information to be deleted. When the device is in low security mode, this will not have any effect on the devices operation, but whilst in high security mode, this will mean that another device can pair with adapter, or that the original device must expire its bond in order to reconnect.

b)Resets adapter to factory defaults.

A long press (more than 3 seconds) of the reset button causes all factory defaults to be restored. Care should be taken here to remember that these “factory” settings can actually be updated via the interactive menu and thus may not be the same as the device was shipped with. The user should also remember that adapter is likely to need it’s parameters re-configuring to ensure communications can be re-established with either the local serial device, or remote Bluetooth device.
