| .SH DESCRIPTION |
| .LP |
| L2ping sends a L2CAP echo request to the Bluetooth MAC address |
| .I bd_addr |
| given in dotted hex notation. |
| .SH OPTIONS |
| .TP |
| .BI \-i " <hciX>" |
| The command is applied to device |
| .BI |
| 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. |
| .TP |
| .BI \-s " size" |
| The |
| .I size |
| of the data packets to be sent. |
| .TP |
| .BI \-c " count" |
| Send |
| .I count |
| number of packets then exit. |
| .TP |
| .BI \-t " timeout" |
| Wait |
| .I timeout |
| seconds for the response. |
| .TP |
| .BI \-d " delay" |
| Wait |
| .I delay |
| seconds between pings. |
| .TP |
| .B \-f |
| Kind of flood ping. Use with care! It reduces the delay time between packets |
| to 0. |
| .TP |
| .B \-r |
| Reverse ping (gnip?). Send echo response instead of echo request. |
| .TP |
| .B \-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). |
| .TP |
| .I bd_addr |
| The Bluetooth MAC address to be pinged in dotted hex notation like |
| .B 01:02:03:ab:cd:ef |
| or |
| .B 01:EF:cd:aB:02:03 |
