24.5 Hopping
24.5.1 Introduction
The “bt_util” command is used to configure the device in order to transmit packets in required channels when
random hopping feature is enabled.
24.5.2 IOCTL
The parameters of "bt_util" command are as follows:
./bt_util afh_map <classic_le_mode> <channel_bit_map>
24.5.3 Description
Classic_le_mode: 2 – BLE
channel_bit_map: It is bitmap to transmit in required channels. It is 10 bytes in length. Range:
00000000000000000001 to 7FFFFFFFFFFFFFFFFFFF
Bit number is the channel number used.
24.5.4 Appendix
Note:-
The above configuration is used only when you have kept the device in transmit burst mode and has made random
hopping as "enabled".
For more details in "Configuration of device in the transmit burst mode", please refer to the section

Examples:
. /bt_util afh_map 2 7FFFFFFFFFFFFFFFFFFF
Classic_le_mode – 2
channel_bit_map – 7FFFFFFFFFFFFFFFFFFF (here all the bits of bit map are set. So, transmission happens in all
the channels randomly)
. /bt_util afh_map 2 00000000000000000007
Classic_le_mode – 2
channel_bit_map –00000000000000000007 (here only lower 3 bits of bit map are set. So, transmission happens in
0,1 & 2 channels randomly)
/bt_util afh_map 2 70000000000000000000
Classic_le_mode – 2
