goopendrop's Issues

key requirement clarification

In the readme it says:

You must Do the extraction Step of Keys

Does this mean that you are required to extract your keys to send any airdrop, or just airdrops to devices in "contact only" mode?

BTW this looks really cool! Thanks for uploading!

help with usage

It was quite confusing for me how to install and use this code. Has anyone used it on a raspberry pi?

I'm trying to do this, with a ZERO RPI 2 Ubuntu.

Can someone help me?

I'm quite confused and what steps should I follow to install and how to call this code in a python script to scan or send some file. thank you for any help.

Ps, I got the keys, I also need to know where to put them…

File receiving very slow with nexmon (packet injection broken?)

(I slightly modified the code to run OWL with the command "owl", "-i", wlanDevName, "-h", OwlName, "-N" instead of "owl", "-i", wlanDevName, "-h", OwlName, "-c", owlChannel, however I can't see this being the reason for my problem)

Whenever I receive a file over AirDrop from multiple different iOS devices (iPhone 6 (iOS 12.5.5) and iPad Pro 3rd Gen (iOS 16.3.1)), it takes a while for GoOpenDrop to accept the request and afterwards sending takes forever.

For example, a 5MB file which i can receive with opendrop on my MacBook Pro 2012 (running macOS Ventura with OpenCore) in 1 second takes multiple minutes to receive with GoOpenDrop.

I'm using a Raspberry Pi 3 with the integrated WiFi module patched with nexmon and my fork of GoOpenDrop, but as stated above I doubt that's where my problem is coming from.

A few days ago I had opendrop running on my Pi with owl and receiving was just as fast as it is now on my MacBook. I can't replicate this anymore as my Apple devices just don't find my Raspberry Pi with opendrop anymore, likely due to the absence of BLE.

Given the slow speeds and that it worked with opendrop, I'm assuming the problem has to do with GoOpenDrop not doing the packet injection properly for the Apple device to know that it received the datachunk, but I don't know much about how opendrop works so I have no idea how to fix that.

Some parts of packet injection do work properly though, as when sending does finally complete, the Apple devices displays "Sent", meaning it knows the file was received by GoOpenDrop.

GIN-debug warning

When running goopendrop, I'm getting this warning:

Stuck on "Waiting for AWDL Interface (awdl0) to Start"

On a desktop computer,
Software: Ubuntu 22.04.1 LTS
Go version: "go version go1.18.1 linux/amd64"
Hardware device is a Ralink Technology, Corp. MT7601U Wireless Adapter.

Ran
sudo iw phy phy1 interface add mon0 type monitor
sudo ifconfig mon0 up

key extraction

Hello, I have a problem with the MAKE command step.

Raspberry Pi Zero W 1.1 shows error

after running ./Build_Pi.sh to set up,
running sudo ./goopendrop ./config.json in ~/GoOpenDrop/out/arm returns Illegal instruction
running sudo ./goopendrop ./config.json in ~/GoOpenDrop/out/arm64 returns ./goopendrop: 4: Syntax error: Unterminated quoted string
go version is go version go1.19.2 linux/arm, uname -r is 5.15.61+.
I know that it's not built the Pi Zero W, but I wanted to try it out anyway.
Love what you're doing. Keep it up!

Send from Linux/Mac to iPhone ok?

Can anyone send from Linux/Mac to iPhone with this project?
If yes, what is the OSX version & what is the IOS version & iphone model ?

GoOpenDrop neither sending nor recieving

When I run sudo ./goopendrop ./config.json, the output is:

INFO[0000] Config File: ./config.json
INFO[0000] Using Wifi Interface: mon0
WARN[0000] Waiting for AWDL Interface (awdl0) to Start
[GIN-debug] [WARNING] Creating an Engine instance with the Logger and Recovery middleware already attached.
...

When I open my iPhone (running iOS 16), go to the photos app, select a photo, and open the airdrop menu it updates:

INFO[0022] Airdrop Beacons Received from address=xx:xx:xx:xx:xx:xx, with rssi=-33

but GoOpenDrop doesn't appear on the iPhone at all.

I have a folder under OUTBOX with the name "test", the same name as my iPhone. Inside that folder is a photo, verified.png. According to the readme, that photo is supposed to be sent to my phone, but nothing like that happens.

My hardware is a raspberry pi zero w 1.1, with a Ralink Technology, Corp. MT7601U Wireless Adapter. I'm using official apple keys.

Any way of using without expensive keys?

Is your feature request related to a problem? Please describe.
Is there any way to not use the keys, e.g. by using a flag or doing something similar?

Additional context
The developer certificate needed for extracting keys requires a yearly fee of 99$
