opendrop won't find an iphone

[warpdesign]

I was able to receive files (although I don't know where the file was put), but opendrop won't find the same iphone when attempting to send a file.

I only get this message:

Looking for receivers. Press enter to stop ...

The iPhone needs to be discoverable by everyone.

It is set to be discoverable by everyone but it still won't be detected.

You need to send an specific BLE advertisement to make the receiver listen. You can achieve this by using a second apple device initiating an airdrop communication.

Or you might also simulate your own "airdrop beacon" using bluez.

1.: download bluez wget www.kernel.org/pub/linux/bluetooth/bluez-5.43.tar.xz

2.: unpack and modify the example test/example-advertisement, change init of TestAdvertisement class, like:

def __init__(self, bus, index):
    # https://www.usenix.org/system/files/sec19-stute.pdf
    company_id =   0x004C # Apple Inc.
    beacon_type = [0x05, 0x12]
    # Zero bytes followed by 0x01
    zero_bytes =  [0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x01]
    # bad coded robo adds
    contact_id =  [0xBA, 0xDC, 0x0D, 0xED, 0x30, 0xB0, 0xAD, 0xD5]
    end_zero =    [0x00]
    Advertisement.__init__(self, bus, index, 'peripheral')
    self.add_manufacturer_data(company_id, beacon_type + zero_bytes + contact_id + end_zero)

3.: run python ./bluez-5.43/test/example-advertisement.ibeacon

sorry , i can't understand a lot . " simulate your own "airdrop beacon" using bluez.", do you mean that " i make iphone jailbroken ,and run "python ./bluze-z5.43/text/xxxxx.ibeacon".????

Or something else? please help me . see here : https://github.com/seemoo-lab/opendrop/issues/51

The simple answer to this issue is that the current implementation cannot discover Apple devices if they do not receive a specific Bluetooth message. As @jamjamg describes it already you would need a second Apple device that basically "wakes" the devices up so they connect to OpenDrop. This feature relies on Bluetooth and could be added manually with something like bluez, but it might be some work to get there and is not simple for a non-programming user.

You can still use the receive feature, because then device will connect automatically. Refer to this issue: https://github.com/seemoo-lab/opendrop/issues/51

Hello, I am sorry to bump this issue, but @jamjamg , for me your script returns

bret@luis2:~/bluez-5.43/test$ python ./example-advertisement.ibeacon
LEAdvertisingManager1 interface not found

What even is LEAdvertisingManager1, what does it do and how do I get it?
