l2ping

L2PING(8)						    Linux System Administration 						 L2PING(8)

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 speci-
	      fied, 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
