# Utangulizi
|
|
|
|
Inapatikana tangu spesifikasisi ya Bluetooth 4.0, BLE inatumia tu vituo 40, ikifunika anuwai ya 2400 hadi 2483.5 MHz. Kinyume chake, Bluetooth ya jadi inatumia vituo 79 katika anuwai hiyo hiyo.
|
|
|
|
Vifaa vya BLE vinawasiliana kwa kutuma **pakiti za matangazo** (**beacons**), pakiti hizi zinatangaza uwepo wa kifaa cha BLE kwa vifaa vingine vya karibu. Beacons hizi wakati mwingine **zinasambaza data** pia.
|
|
|
|
Kifaa kinachosikiliza, pia kinachojulikana kama kifaa cha kati, kinaweza kujibu pakiti ya matangazo kwa **ombio la SCAN** lililotumwa mahsusi kwa kifaa kinachotangaza. **Jibu** kwa skani hiyo linatumia muundo sawa na pakiti ya **matangazo** ikiwa na taarifa za ziada ambazo hazikuweza kuingia kwenye ombi la matangazo la awali, kama vile jina kamili la kifaa.

|
Byte ya preamble inasawazisha masafa, wakati anwani ya ufikiaji ya byte nne ni **kitambulisho cha muunganisho**, ambacho kinatumika katika hali ambapo vifaa vingi vinajaribu kuanzisha muunganisho kwenye vituo sawa. Kisha, Kitengo cha Data ya Protokali (**PDU**) kina **data za matangazo**. Kuna aina kadhaa za PDU; zile zinazotumika sana ni ADV\_NONCONN\_IND na ADV\_IND. Vifaa vinatumia aina ya PDU ya **ADV\_NONCONN\_IND** ikiwa **havikubali muunganisho**, vinatoa data tu katika pakiti ya matangazo. Vifaa vinatumia **ADV\_IND** ikiwa **vinakubali muunganisho** na **kusitisha kutuma matangazo** mara tu **muunganisho** unapokuwa **umeanzishwa**.

## GATT
|
|
|
|
**Profaili ya Sifa ya Kijeneriki** (GATT) inaelezea jinsi **kifaa kinapaswa kuunda na kuhamasisha data**. Unapokuwa unachambua uso wa shambulio la kifaa cha BLE, mara nyingi utaelekeza umakini wako kwenye GATT (au GATTs), kwa sababu ndivyo **ufanyaji kazi wa kifaa unavyoanzishwa** na jinsi data inavyohifadhiwa, kuunganishwa, na kubadilishwa. GATT inataja sifa, maelezo, na huduma za kifaa katika jedwali kama thamani za 16- au 32-biti. **Sifa** ni thamani ya **data** inayotumwa kati ya kifaa cha kati na cha pembeni. Sifa hizi zinaweza kuwa na **maelezo** yanayotoa **taarifa za ziada kuhusu hizo**. **Sifa** mara nyingi **zinaunganishwa** katika **huduma** ikiwa zinahusiana na kutekeleza hatua maalum.

# Uhesabuji
|
|
```bash
|
|
hciconfig #Check config, check if UP or DOWN
|
|
# If DOWN try:
|
|
sudo modprobe -c bluetooth
|
|
sudo hciconfig hci0 down && sudo hciconfig hci0 up
|
|
|
|
# Spoof MAC
|
|
spooftooph -i hci0 -a 11:22:33:44:55:66
|
|
```
|
|
## GATTool
|
|
|
|
**GATTool** inaruhusu **kuanzisha** **muunganisho** na kifaa kingine, kuorodhesha **sifa** za kifaa hicho, na kusoma na kuandika sifa zake.\
|
|
GATTTool inaweza kuzindua shell ya mwingiliano kwa chaguo la `-I`:
|
|
```bash
|
|
gatttool -i hci0 -I
|
|

```
|
|
## Bettercap
|
|
```bash
|
|
# Start listening for beacons
|
|
sudo bettercap --eval "ble.recon on"
|
|
# Wait some time
|
|
>> ble.show # Show discovered devices
|
|
>> ble.enum <mac addr> # This will show the service, characteristics and properties supported
|
|
|
|
# Write data in a characteristic
|
|
>> ble.write <MAC ADDR> <UUID> <HEX DATA>
|
|
>> ble.write <mac address of device> ff06 68656c6c6f # Write "hello" in ff06
|
