l2ping - Send L2CAP echo request and receive answer l2ping [\| -i <hciX> \|] [\| -s size \|] [\| -c count \|] [\| -t timeout \|] [\| -d delay \|] [\| -f \|] [\| -r \|] [\| -v \|] bd_addr

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

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