Check your mobile device's and your Bluetooth Serial Port's documentation for the steps. The pairing step involves starting the process by searching both devices and entering the correct pairing code. Once the proper Bluetooth hardware is present on your mobile device and the SPP Profile is supported by the Bluetooth stack, next step to check is the Pairing of your device. Check Hardware page to check compatibility before wasting time trying to connect the Bluetooth remote device when your mobile device is incapable. TcpdumpBluetooth.pcap (libpcap) Capture created by the Bluetooth-sniffing feature in the latest libpcap/tcpdump CVS.First of all, not all mobile devices may have the Bluetooth Hardware even if it does, it may not work for Serial Port method of communication via Bluetooth Radio. SampleCaptures/Bluetooth1.cap (Linux BlueZ hcidump) Contains some Bluetooth packets captured using hcidump. SampleCaptures/l2ping.cap (Linux BlueZ hcidump) Contains some Bluetooth packets captured using hcidump, the packets were from the l2ping command that's included with the Linux BlueZ stack. It contains better Bluetooth support.īluetooth A2DP Content Protection Header SCMS-Tīluetooth VDP Content Protection Header SCMS-T The development version 1.11 (or later), is quite stable and can be used for Bluetooth purposes. In version 1.10, Wireshark supports most Bluetooth profiles and protocols.
NET library 32feet.NET produces libpcap captures when using the Stonestreet One Bluetopia stack on Windows Mobile, see the Diagnostics section in its documentation at 32feet.NET: Stonestreet One Bluetopia stack. Other platforms that can create capture files include the following. In addition, Wireshark can read capture files created by the HCIDUMP utility that is available with the Linux and (I think) the BSD Bluetooth stack, and can also read capture files from the macOS PacketLogger Bluetooth logger application. The original format uses protocol id LINKTYPE_BLUETOOTH_HCI_H4 and the new format uses LINKTYPE_BLUETOOTH_HCI_H4_WITH_PHDR ( LINK-LAYER HEADER TYPES). Note that this field is big-endian even if the pcap file has been written in little-endian everywhere else ( Development/LibpcapFileFormat). A newer file format includes the direction information as a 4-byte field where bit0 is set if the packet was 'received', see LINKTYPE_BLUETOOTH_HCI_H4_WITH_PHDR at LINK-LAYER HEADER TYPES. The original pcap format didn't store whether the packet was being sent or received ( bug 1751). As of, Gentoo Linux has libpcap with Bluetooth support in its mainline repository (portage).) Wireshark can also read captures in that format.
(In Linux distributions that come with pre-1.0.0 versions of libpcap, libpcap doesn't support capturing on Bluetooth devices, so you would have to get libpcap 1.0.0 or later from, install it, and build Wireshark with that version of libpcap in order to capture on Bluetooth devices. There is a libpcap format defined for Bluetooth frames, and support in libpcap 1.0.0 and later for capturing on Bluetooth devices in Linux Wireshark, if linked with that version of libpcap, is able to capture on Bluetooth devices. The Bluetooth stack is partially implemented and Wireshark can dissect several of the layers and protocols of the stack. Time Source Destination Protocol Infoįrame 11 (57 bytes on wire, 57 bytes captured) (data)īTHCI_SCO: Synchronous Connection Oriented traffic. HCI_H4: This is not a protocol but more an encapsulation format that wireshark implements.Īt the lowest layer implemented in Wireshark, Bluetooth consists of 4 different types of frames:īTHCI_ACL: Asynchronous Connectionless traffic.

Bluetooth is a family of protocols that are popular for building wireless accessories.
