NAME
l2ping − Send L2CAP echo request and receive answer
SYNOPSIS
l2ping [−i <hciX>] [−s size] [−c count] [−t timeout] [−d delay] [−f] [−r] [−v] bd_addr
DESCRIPTION
L2ping sends a L2CAP echo request to the Bluetooth MAC address bd_addr given in dotted hex notation.
OPTIONS
−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
