I am trying to get raw BLE advertising information using Bluez tool such as hcitool in a quick and dirty way. Someone (in this post http://comments.gmane.org/gmane.linux.bluez.kernel/43422) modified the "print_advertising_devices" function in "tools/hcitool.c", and he claimed successfully printing out the advertising data from command "sudo hcitool lescan". The "hcitool.c" can be conveniently viewed here http://git.kernel.org/cgit/bluetooth/bluez.git/tree/tools/hcitool.c . I guess the pointer "info" with type of "le_advertising_info" (defined in "lib/hci.h") in "print_advertising_devices" function has all advertising information . A closer look into the struct definition typedef struct { uint8_t evt_type; uint8_t bdaddr_type; bdaddr_t bdaddr; uint8_t length; uint8_t data[0]; } __attribute__ ((packed)) le_advertising_info; reveals that the data array has zero length. In that case, where is the advertising data? -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
