3.7. Resetting BL-521

The BL-521 has a “reset button” located on the side of the case. 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 BL-521, or that the original device must

expire its bond in order to reconnect.

b) Resets BL-521 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

BL-521 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.

3.8. Troubleshooting the configuration menu

If you are having difficulty connecting to the BL-521 configuration menu, follow these few simple steps…

a) Ensure the power adapter is plugged in and switched on – The LED’s will light up on the BL-521

b) Ensure the attached cable AND the gender converter are attached securely to an available RS232 port on

your PC. If you are using a terminal or other “peripheral” type device, you may not need the gender

converter attached.

c) Check that your terminal/application has the correct communications parameters set. As it leaves the

factory, the BL-521 is set to 115200 baud, no parity, 8 data bits, 1 stop bit.

d) If you are still unable to communicate to the device, it may need a reset. Follow the instructions for resetting

your device.
