2. Unlock your iPhone/iPad
3. Connect using a certified cable (I used the USB-lightning charger
cable that came with my iPad)

I connected with bluetooth. The connection seems to be real, but the
options are for a WiFi access point or an audio source. If I choose
the audio source the iPhone's audio comes out through the Pi's speakers.

4. Tap "Trust" on the iPhone/iPad

There's an option on the Pi to trust the iPhone, but no prompt that I
can find on the iPhone to trust the Pi, at least not in the Settings>
Bluetooth page.

5. Dismiss error dialog on the Pi (may be hidden behind file explorer
window)

No error dialog, and I can't seem to open a file explorer window. In
the BlueTooth Devices window the options to browse the device and
send files are greyed out.

6. Click Open on that file explorer window

No can do 8-(

7. My "DCIM" photos folder opened and I SEEMED to be able to copy photos

but they were unreadable by ImageViewer and Chromium.

Well, you got farther than I did......

iPhones don't do file sharing over Bluetooth, so that's not an option.

(there are a few implementations of the AirDrop protocol, which uses
Bluetooth and ad-hoc wifi, but none I'd regard as stable enough for everyday use)

I don't know about Iphones, but every Android I know can do FTP file
server over WLAN and be addressed from the desktop.

I do the above because cable does not work any more. I used to be able
to plug the phone in and see a standard external disk drive. No more. Everything now is some proprietary junk I don't want.

there one available as an app?

As you may guess, I don't have an iPhone, its possible it has an SSH or
FTP server installed since most Apple or Windows desk/laptops won't.

I have often used sftp, a command line SSH file transfer tool, to move
files between systems which have an sshd server installed. On my RPi
(Buster) system sftp seems to have been installed as part of the SSH
clients package, so you may already have it. If not, you can always
install filezilla and use that instead.

You've raised a good point. Both the iPhone and the Pi are on the

BlueTooth solely because my old phone used it and my only Lightning

Probably, although see below for why that's not very useful.

iPhones don't really have a user-visible filesystem[1], so they definitely don't have an SSH or FTP server installed.

I have an app 'FTP Manager' that allows it to be an SFTP client, which
suffices to push and pull files from the iPhone end. Because of the lack of filesystem you are limited to the files FTP Manager can see, or using the 'Share' mechanism to send files from other apps to FTP Manager.

[1] Essentially an app can have its own files (eg the documents created in
the app) but there is no global view of the filesystem so apps can't see
files owned by other apps, nor any system files. There is a 'Files' app,
which can be used in limited circumstances to manually move files from one
app to another. Also some media like photos can be accessed by multiple
apps (with restrictions).

Interesting! In that case, how do Bluetooth apps transfer files, i.e. do
they have the same limitations as your 'FTP Manager'?

And, of course I should have said 'sshd process' rather than FTP server,
since AFAIK the sshd daemon can act as a file server when sftp is used to transfer files to or from a *nix box.

Yes. Essentially there are no bluetooth apps; sharing is done from the app
that owns the files and the medium can be "Air Drop" which is mainly
bluetooth.
(Of course there are system programs that manage bluetooth connections and
the files transported on it, but they are not actors from the user's point
of view.)

Yes. Essentially there are no bluetooth apps; sharing is done from the app that owns the files and the medium can be "Air Drop" which is mainly bluetooth.

AirDrop is mostly ad-hoc wifi, with Bluetooth used for initial discovery and handshaking. That's why it's a lot faster than Bluetooth. In general Bluetooth is so slow that it's barely usable for transferring files of any
size (I tried to use it for videos from Android - really bad idea).

The main use for Bluetooth on iPhones is audio and networking (tethering).

Ah ok, yes. I knew Bluetooth was necessary and it only works in the
proximity dictated by it; I should have searched for actual transfer
mode though, thanks.

It had enough latency that White's Metal Detectors came up with a custom interface for the Spectra V3i wireless headphones. Bluetooth ended
up signalling finds long after the coil had passed beyond the actual
target.

{Hmm, pity... White's has gone out of business, and I don't trust Garrett
to make use of the IP acquisition to produce the fancy models}

It turns out that gtkpod is able, in a rather awkward way, to allow
moving photos from an iPhone to a Pi. If one starts gtkpod and then
plugs in the iPhone using a lightning-usb cable gtkpod will create
a desktop icon representing the iPhone. Applications can open image
or video files via the icon. Once opened, the file can be "saved as"
to the Pi's filesystem. Simply dragging the file icons won't work,
something gets screwed up and they can't be opened once moved. If
they are opened before moving and saved by the opening program to
the Pi's filesystem then the file integrity is preserved.

The sequence is
start gtkpod
plug in the iphone
load iPod(s) using down arrow icon (3rd row from top, 2nd from left)
A warning dialog box saying iPod directory structure not found
click create directory structure
Select the mount point and model from the drop-down menus

A long warning appears, but can be dismissed, and two iPhone
icons appear just below the trash icon. They can be traversed
like any storage device, but files can't be dragged, they have
to be opened and saved to the Pi.

The iPhone isn't remembered in the list of possible devices,
although the iPod seems to be. So, one has to go through this
drill from the beginning on every attempt.

Certainly a nuisance, but doable.

Thanks for reading, I was surprised by the discovery.
