A BTLE (Bluetooth Low energy)/BT4.0 radio packet sniffer/scanner and sender ( build based on hackrf and bladeRF ) . Also see my tech blog: http://sdr-x.github.io

==========================================================================

News (See complete introduction section after news section):

Nov. 2015: So excited that the HACKRF BTLE packet sniffer/scanner can follow hopping data channels automatically now! Just like TI's sniffer.

http://sdr-x.github.io/BTLE-SNIFFER/

New added options:

-o --hop

This will turn on data channel tracking (frequency hopping) after link setup information is captured in ADV_CONNECT_REQ packet.

-f --freq_hz (need argument)

This frequency (Hz) will override channel setting (In case someone want to work on freq other than BTLE. More general purpose).

-m --access_mask (need argument)

If a bit is 1 in this mask, corresponding bit in access address will be taken into packet existing decision (In case someone want a shorter/sparser unique word to do packet detection. More general purpose).

Nov. 2015: BTLE packet sniffer/scanner btle_rx works! Support HACKRF currently. Usage:

btle_rx -c chan -g gain -a access_addr -k crc_init -v -r

chan: Channel number. Default value 37 (one of ADV chan). Valid value 0~39 (all ADV and DATA chan).

gain: VGA gain. default value 6. valid value 0~62. LNA has been set to maximum 40dB internally. Gain should be tuned very carefully to ensure best performance under your circumstance. Suggest test from low gain, because high gain always causes severe distortion and get you nothing.

access_addr: Access address. Default 8e89bed6 for ADV channel 37 38 39. You should specify correct value for data channel according to captured connection setup procedure.

crc_init: Default 555555 for ADV channel. You should specify correct value for data channel according to captured connection setup procedure.

-v: Verbose mode. Print more information when there is error

-r: Raw mode. After access addr is detected, print out following raw 42 bytes (without descrambling, parsing)

ATTENTION: To support fast/realtime sender and scanner/sniffer, I have changed:

lib_device->transfer_count to 4
lib_device->buffer_size to 4096

in hackrf driver: hackrf.c. You should also do that change to your driver source code and re-compile, re-install as instructed in hackrf

See a comparison with TI's packet sniffer here: http://sdr-x.github.io/BTLE-SNIFFER/

Sep. 2015: Fixed-point version. Add new packet type: discovery. Open LightBlue APP in your iPhone/device, then:

btle_tx packets_discovery.txt
(packets_discovery.txt is under host/btle-tools/src)

You will see a device named as "CA1308 11950 22.626 113.823 8" in your LightBlue APP.

DO NOT use space character " " in a command line packet descriptor. You CAN use space in the txt file packet descriptor like above. Command line of above example:

btle_tx 37-DISCOVERY-TxAdd-1-RxAdd-0-AdvA-010203040506-LOCAL_NAME09-CA1308/11950/22.626/113.823/8 r40

"btle_tx 37-DISCOVERY-TxAdd-1-RxAdd-0-AdvA-010203040506-LOCAL_NAME09-CA1308 11950 22.626 113.823 8 r40" in command line will get ERROR!

"-" is magic character which is used to separate different fields in packet descriptor. DO NOT use "-" inside each field.

Aug. 2014: Fix packet loss bug. And, add bladeRF support:

cmake ../ -DUSE_BLADERF=1  (without -DUSE_BLADERF=1 means HACKRF will be used by default)

(Don't forget removing all files in build directory before above command!)

==========================================================================

Introduction

All ADV and DATA channel link layer packet formats are supported. (Chapter 2&3, PartB, Volume 6, Core_V4.0.pdf )

btle_tx transmits arbitrary pre-defined BTLE signal/packet sequence, such as raw bits to GFSK modulator, iBeacon packet, Connection establishment procedure packet in TI's website, or any other packets you want.

btle_rx sniffs/scans BTLE packets in the air, just like TI'S packet sniffer.

See btle_rx video demo (youtube) or btle_rx video demo (in China) and btle_tx video demo 1 (outside China) or btle_tx video demo 2 (inside China)

1. Build:

cd host
mkdir build
cd build
cmake ../      (without -DUSE_BLADERF=1 means HACKRF will be used by default)
make
sudo make install  (or not install, just use btle_tx in btle-tools/src)

2. btle_tx usage

Usage method 1:

btle_tx packet1 packet2 ... packetX ...  rN

Usage method 2:

btle_tx packets.txt

In method 2, just those command line parameters (packet1 ... rN) in method 1 are written/grouped in a .txt file as input of btle_tx tool. One parameter one line. A line start with "#" is regarded as comment. See packets.txt example in btle-tools/src.

"packetX" is one string which describes one packet. All packets compose a packets sequence.

"rN" means the sequence will be repeated for N times. If it is not specified, the sequence will only be sent once.

Format of packet descriptor "packetX"

channel_number-packet_type-field-value-field-value-...-Space-value

Each descriptor string starts with BTLE channel number (0~39), then followed by packet_type (RAW/iBeacon/ADV_IND/ADV_DIRECT_IND/etc. See all format examples at the end), then followed by field-value pair which is packet_type specific, at last there is Space-value pair (optional) where the value specifies how many millisecond will be waited after this packet sent.

a). iBeacon example: (iBeacon principle: http://www.warski.org/blog/2014/01/how-ibeacons-work/ )

btle_tx     37-iBeacon-AdvA-010203040506-UUID-B9407F30F5F8466EAFF925556B57FE6D-Major-0008-Minor-0009-TxPower-C5-Space-100     r100

Above command sends iBeacon packet and repeats it 100 times with 100ms time space (If you have "Locate" app in your iPhone/iPad, it will detect the packet and show the iBeacon info.). The packet descriptor string:

37-iBeacon-AdvA-010203040506-UUID-B9407F30F5F8466EAFF925556B57FE6D-Major-0008-Minor-0009-TxPower-C5-Space-100

37 -- channel 37 (one of BTLE Advertising channel 37 38 39)

iBeacon -- packet format key word which means iBeacon format. (Actually it is ADV_IND format in Core_V4.0.pdf)

AdvA -- Advertising address (MAC address) which is set as 010203040506 (See Core_V4.0.pdf)

UUID -- here we specify it as Estimote’s fixed UUID: B9407F30F5F8466EAFF925556B57FE6D

Major -- major number of iBeacon format. (Here it is 0008)

Minor -- minor number of iBeacon format. (Here it is 0009)

Txpower -- transmit power parameter of iBeacon format (Here it is C5)

Space -- How many millisecond will be waited after this packet sent. (Here it is 100ms)

b). Connection establishment example: (See "Connection establishment" part of http://processors.wiki.ti.com/index.php/BLE_sniffer_guide )

btle_tx     37-ADV_IND-TxAdd-0-RxAdd-0-AdvA-90D7EBB19299-AdvData-0201050702031802180418-Space-1      37-CONNECT_REQ-TxAdd-0-RxAdd-0-InitA-001830EA965F-AdvA-90D7EBB19299-AA-60850A1B-CRCInit-A77B22-WinSize-02-WinOffset-000F-Interval-0050-Latency-0000-Timeout-07D0-ChM-1FFFFFFFFF-Hop-9-SCA-5-Space-1     9-LL_DATA-AA-60850A1B-LLID-1-NESN-0-SN-0-MD-0-DATA-XX-CRCInit-A77B22-Space-1

Above simualtes a Connection establishment procedure between device 1 and device 2.

The 1st packet -- device 1 sends ADV_IND packet in channel 37.

The 2nd packet -- After device 2 (in scanning state) receives the ADV packet from device 1, device 2 sends CONNECT_REQ packet to request connection setup with device 1. In this request packet, there are device 2 MAC address (InitA), target MAC address (device 1 MAC address AdvA), Access address (AA) which will be used by device 1 in following packet sending in data channel, CRC initilization value for following device 1 sending packet, Hopping channel information (ChM and Hop) for data channel used by device 1, etc.

The 3rd packet -- device 1 send an empty Link layer data PDU in channel 9 (decided by hopping scheme) according to those connection request information received from device 2. ("XX" after field "DATA" means there is no data for this field )

Time space between packets are 1s (1000ms). Tune TI's packet sniffer to channel 37, then above establishment procedure will be captured.

c). Discovery packets example: (which can show any name or services in receiver/scanner, such as LightBlue):

Open LightBlue APP in your iPhone/device, then:

btle_tx packets_discovery.txt
(packets_discovery.txt is under host/btle-tools/src)

You will see a device named as "CA1308 11950 22.626 113.823 8" in your LightBlue APP.

3. btle_rx Usage

btle_rx -c chan -g gain -a access_addr -k crc_init -v -r

chan: Channel number. Default value 37 (one of ADV chan). Valid value 0~39 (all ADV and DATA chan).

access_addr: Access address. Default 8e89bed6 for ADV channel 37 38 39. You should specify correct value for data channel according to captured connection setup procedure.

crc_init: Default 555555 for ADV channel. You should specify correct value for data channel according to captured connection setup procedure.

-v: Verbose mode. Print more information when there is error

-r: Raw mode. After access addr is detected, print out following raw 42 bytes (without descrambling, parsing)

New added options:

-o --hop

This will turn on data channel tracking (frequency hopping) after link setup information is captured in ADV_CONNECT_REQ packet.

-f --freq_hz (need argument)

This frequency (Hz) will override channel setting (In case someone want to work on freq other than BTLE. More general purpose).

-m --access_mask (need argument)
