1. NAME

l2ping - Send L2CAP echo request and receive answer

2. SYNOPSIS

l2ping [  -i <hciX>  ] [  -s size  ] [  -c count  ] [  -t timeout  ] [  -d delay  ] [  -f  ] [  -r  ] [  -v  ] bd_addr

3. DESCRIPTION

L2ping sends a L2CAP echo request to the Bluetooth MAC address bd_addr given in dotted hex notation.

4. OPTIONS

  • -i <hciX>
        The command is applied to device

I hciX , which must be the name of an installed Bluetooth device (X = 0, 1, 2, ...) If not specified, the command will be sent to the first available Bluetooth device.

  • -s size
        The size of the data packets to be sent.
  • -c count
        Send count number of packets then exit.
  • -t timeout
        Wait timeout seconds for the response.
  • -d delay
        Wait delay seconds between pings.

-f

    Kind of flood ping. Use with care! It reduces the delay time between packets to 0.

-r

    Reverse ping (gnip?). Send echo response instead of echo request.

-v

    Verify response payload is identical to request payload. It is not required for remote stacks to return the request payload, but most stacks do (including Bluez).

  • bd_addr
        The Bluetooth MAC address to be pinged in dotted hex notation like

01:02:03:ab:cd:ef or

01:EF:cd:aB:02:03
