🌸 SYNOPSIS 🌸

l2ping [OPTIONS] bd_addr

🦋 DESCRIPTION 🦋

l2ping(1) sends a L2CAP echo request to the Bluetooth MAC address bd_addr given in dotted hex notation. that’s lowkey the whole plot, bestie. ✨

💅 OPTIONS 💅

• -i <hciX> — this applies the command to device hciX, and hciX must be the name of an installed Bluetooth device (X = 0, 1, 2, ...). If you don’t specify it, the command goes to the first available Bluetooth device. 🫶
• -s size — sets the size of the data packets to be sent. ✨
• -c count — sends count number of packets, then exits. periodt. 💅
• -t timeout — waits timeout seconds for the response. 💜
• -d delay — waits 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?). Sends an echo response instead of an echo request. 🙈
• -v — verifies the response payload is identical to the 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. 🎀
