24.4.2 IOCTL
The following command can be given to start the reception
./ble_receive <access_addr> <data_legth_indication> <scrambler_seed> <ble_rate> <rx_channel_index>
<tx_channel_index> <le_channel_type> <hopping_type> <ant_sel> <loop_back_mode> <pwrsave_options>

24.4.4 Appendix
Frequencies and channel numbers used for Bluetooth LE Mode are same as BLE TX case.
Examples:
For receiving a BLE-1Mbps Advertising packet with Access Address of 0x71764129 and packet length of 250bytes on
2478MHz with the following parameters
scrambler_seed : 0
hopping_type: disable
ant_sel : u.f.l
loop_back_mode : Disabled
Stop the Reception first before starting of Receiving
