Have you located the '/sdcard/' or '/mnt/sdcard/'?
The "sdcard" is the internal, embedded "external storage" (while the SD-Card slot would be an "External SD").

Transferring data from a fixed device, you are probably better set with a USB cable.
The wireless way is useful but possibly more of a potential asset to transfer data from other mobile devices - i.e. it's anyway less direct than a USB cable.

Concerning file transfer to and from Max2 I made the observation that (at least on my linux computer using jmtpfs to mount Max2 into my local file system) there was a transfer limit of about 800Mbyte max per file. If I try to transfer a bigger file, I get the (not so informative) response that there is no space left on device (which is obviously not true). A workaround would be to initiate file transfer on the linux side by typing:

split -b 800M /path/to/source_file

and then, on Max2, using Termux or another terminal emulator to change to the directory the files were transfered to and then type:

cat x* > name_of_file_to_be_restituted

--------------

Obviously it would be a good idea to have another, secure, way of transfering big files, too. Above technique is secure (because of usb link cable used) but has the file size limit (at least on my machine), and other ways of doing it like using "Wifi File Manager" for example) have security issues, because other computers on the same net might log into your Max2, too. Also, some wifi file transfer apps seem to dial home quite a lot (I saw a lot of activities on tracking sites when testing them). I haven't tested an app that will set up a wifi network itself.

So here's a proposal for a wifi file transfer that is totally secure. It needs a wifi router so can only be used at home (or some other place where you trust the wifi system.) (I most often want to transfer files while at home and I find it inconvinient to use cable because I have to plug it in, it will always charge battery, which is also not so good if it happens too often).

This proposal is, again, for a linux PC on the other side, but should also work on other operating systems if you find appropriate commands to set up key generation and mounting / unmounting. I can only tell about linux.

---------->

I downloaded "simplesshd" from playstore and installed it on Max2. I changed settings to a different port than 2222 (just for fun, a little obscurity) and told it to start the server when starting the application). This will change its button from a "start" and "stop" behaviour to just displaying "quit" when running.

Max2 will display its IP address which can be used for logging in via ssh or for mounting Max2 on the local file system via sshfs (which I use for file transfer). In order to have a secure login and only allow registered PCs to login simplesshd forces you to set up key exchange as the method except for the very first login (which you only use for transfering keys from PC to Max2, then).
Needed only once on every PC that needs to be registered I type in a terminal shell:

ssh-keygen -t rsa

I will answer all question by just typing "Enter" key (nothing else).
This will, in a directory ~/.ssh, create a file id_rsa.pub which is this PC's key now. I should display this file now and mark its content for later pasting it into a command that I need to type on Max2 shell.

I login in into Max2 by typing (square brackets indicating something that needs to be replaced by actual values, square brackets not to be typed in):

ssh -p [my_chosen_port_number_2222_by_default] [IP_address_displayed_by_Max2]

Because this is the first time I log into Max2, the simplesshd app will display a password. I type this passwort at the PC's ssh shell's prompt and I will be logged into Max2, that is, I have a shell running on my PC, being logged into Max2. I should now, in this shell, be in directory ssh (which I can check by typing "pwd" and which I can change using "cd" command) and I will now type

echo "[pasted_content_marked_above]" > authorized_keys

That is, I will type echo and " and then press the middle mouse button which will include the content marked above and then I will type " again and space and > and then the rest of the command.

(If I want to set up more PCs for secure connection, I can use the PC already set up for logging into Max2 for copying over other PCs id_rsa.pub content -- not described here.)

Having done this I can log out of Max2 by typing "exit" in my shell and I can also destroy file ~/.ssh/id_rsa.pub on my PC and change some access rights. So, on the PC I type in its terminal shell:

cd
chmod 700 .ssh
rm .ssh/id_rsa.pub

Now I should install sshfs on my PC (which my package manager should provide) an I will create a directory for it to mount my Max2 to locally, e.g. by typing

sudo mkdir /mnt/max2
sudo chown [my_login_name] /mnt/max2

and then I will be able to mount my Max2 into my PC's local file system by typing on the PC side (if simplesshd is running on the Max2 side, of course) (one command line, no line breaks):

sshfs -p [port_defaults_to_2222] user@[IP_address_as_displayed_by_simplesshd_app_on_Max2]:/storage/emulated/0 /mnt/max2

I can now access Max2 via its mount point /mnt/max2 which I can, for example, open in pcmanfm or any other file explorer and copy files to or from. I might of course just use the command line for copying, though (see below for an example of syncing using rsync).

Once finished, I can (and must!) unmount Max2 by typing:

fusermount -u /mnt/max2

------------

A convenient way of copying/syncing directories to Max2 would be to use something like:

rsync -rlpgoDvc /from_path[/] /to_path[/]

See rsync's man page for details on when to use trailing slashes and when not. Be aware that it is no good idea to use rsync's -a option (which you would usually to for syncing), because it will include -t (changing sync time on directory) which Max2 does not support.)

So, for example, I could type something like:

rsync -rlpgoDvc /home/my_name/Documents/MagPi-Magazine/ /mnt/max2/

and it would copy all contents of this directory to an equally named directory on Max2. Et voilà!

----------

One last hint: In order to make access more convenient it might be a good idea to set aliasses for mount, unmount and sync command. This might be done by including, e.g. into ~/.bashrc, something like (assuming it's port 2345 and 192.168.2.103 is Max2's ip address it gets on the local network):

alias max2='sshfs -p 2345 user@192.168.2.103:/storage/emulated/0 /mnt/max2'

alias cdmax2='sshfs -p 2345 user@192.168.2.103:/storage/emulated/0 /mnt/max2 && cd /mnt/max2'

alias umax2='cd ; fusermount -u /mnt/max2'

alias max2shell='ssh -p 2345 user@192.168.2.103'

--------

Have fun!

I use ssh with scp and sftp or wget provided by termux.
Ofc you can use rsync too.

Library folder of NEO Reader2 (default Reader App of Max2) is "Books".
But I don't use "Books", I create new folder for myself.

some file manager App have ftp function, I use it for data transfar.

Hi all!
After some delays I got my Onyx Boox Max2 Pro yesterday. In a rush to test it I naively press the power button to switch it on : nothing.
I left it plugged to my computer for 24 hours hoping that may be it is a battery problem and tried again : nothing again.

There is absolutely no indications that the device battery is loading or unloaded.
Has anyone else experienced the same problem ?

Cheers.

Mine worked immediately after unboxing. There is a two seconds delay between press of the power button and light in the blue led nearby.

You should consult with Booxtor.

(Marginal note: I am not sure that computers' USB sockets are the best power source...)

I tried the "sdcard", but got "550 That path is inaccessible, Failed to retrieve directory listing" error message.

Every once in a while I have to transfer some files (usually relatively small .pdfs) on the fly, therefore didn't want to plug the USB all the time. The quickest thing so far has been Bluetooth, but it gets slow + sometimes crashes for multiple/large files.

The wireless way is useful but possibly more of a potential asset to transfer data from other mobile devices - i.e. it's anyway less direct than a USB cable.

Good to know yours work.
I am returning the device and asking for a refund.

Yes, I meant to reassure you (to confirm) that those of the first batch did work immediately after unboxing (I am not sure I was clear).

EDIT: I think you are the first one who reported a factory fault...

Rebooted again and works in English.

Hope his is not a recurring thingies

Hello everyone,

yesterday I received my Onyx Boox Max 2. The device works fine, but when connecting my imac (2015) with the e-reader via usb, the former does not see the internal memory of Max 2, although the e-reader's battery starts immediately charging. Is it a problem of drivers? What can I do? Did anyone experience the same problem?

My laptop with Windows OS does have no problems seeing the e-reader and transferring data poses no difficulties. However I do work mostly on the imac and transferring data via bluetooth (which works) to the device is very slow (44kb/sec !?). This is not an option for larger documents, anyway.

I have reported this issue with Play Services two weeks ago, but we didn't have enough time to provide fixes immediately because production and delivery already has started.

We also are working on other improvements, so please don't worry, if you see some polishing of the software is needed. We are going polish it to you complete satisfaction.

I did the update on my Max 2 and still not reconizing purchased applications. Restarted the device several times too just in case. Not sure what to do next. Hence me on the forums.

Any update on rooting? As mdp already mentioned RNDIS Ethernet option is not supported. A reader does not get an IP address, even though a network interface is created.

Unfortunately, although I see the device in the network connections of the desktop, I do not get an IP address (see screenshot).

Working on it, but if you get a solution sooner...
