Smart cable setup:

The smart cable setup command is used to enable and configure a SmartCable device.

A device BD address is specified with which to automatically establish a connection,

replacing the need for AT connection commands.

It is stored in the non-volatile memory.

The command is:

–

AT+AB SmartCableSetup [BD Addr] [Attempts] [Interval]

If the command is successful, the response is:

–

AT-AB SmartCableConfigDone

In this case, suppose an automatic connection of dongle1 to dongle2 at power-on is

needed, with the possibility to retry for 5 times with an interval of 1 sec between each retry.

The command is:

–

AT+AB SmartCableSetup 0080e1f00002 5 1

This command is stored inside the non-volatile memory and executed at power-on.

In case dongle2 is already powered:

Figure 28.

Smart cable dongle1, dongle2

If dongle2 is not powered or not available, dongle1 automatically retries 5 times.

Figure 29.

Automatic retrial dongle1

If dongle2 is present, dongle1 automatically connects. If dongle2 is unplugged, connection

fails. However, connection is automatically restored if dongle2 is again plugged in during the

interval of retrial assigned to dongle1.
