> It can be used to transmit arbitrary pre-defined BTLE signal/packet sequence, such as raw bits to GFSK modulator, iBeacon packet, Connection establishment procedure packet in TI's website: http://processors.wiki.ti.com/index.php/BLE_sniffer_guide , or any other packets you want. Together with TI's packet sniffer, you will have full TX and RX abilities. See video demo 1 http://youtu.be/Y8ttV5AEb-g (outside China) or video demo 2 http://v.youku.com/v_show/id_XNzUxMDIzNzAw.html (inside China)

> cd host
> mkdir build
> cd build
> cmake ../
> make
> sudo make install (or not install, just use btle_tx in hackrf-tools/src)

> ----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 hackrf-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.

> 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.

> 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. (One "X" 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.
