firmware on my ___”

Next select the COM port to which you have connected your product

How do I terminate a connection

to a device in HyperTerminal

using a BL-521/730, 819 & 830?

Turn the power off on one device and then the other device will be configurable.

If you do not do this then the menu in HyperTerminal will be unresponsive as

the connection will be still present, also, simply power cycling a device will not

terminate the connection.

Once a device is configurable:

You can set the device as a client or server, so that both devices are either

clients or servers i.e. enter svr=0 to set a device as client or svr=1 to set as

server.

Be careful that another device cannot pair with your devices, if you are using

security mode 2 or higher than this will not be possible unless the other device

is using the same pin number.

If you type delpart this will delete the partner device from the connection and

will allow a new partner device to be entered.
