Error that occurs while connecting to rmview

[MinuteLow726]

In earlier versions I was able to use rmview. Currently, I cannot.

The version of the remarkable is 2.11.0.442, and I have the following issue both with Ubuntu and Windows.

I am able to install rmview but when I try to connect to the Remarkable after selecting "Present with Screen Share" the app rmview opens (with the image connecting to Remarkable ...) without showing the screen of the remarkable. Here the red dot works.

On the command prompt, however, a duplicateOptionError is displayed continuously: it appears "received timestamp challenge 1642427633684" and it ends with "While reading from '' [line 56]: option 'direct-hi-android_5bd8' in section 'wifinetworks' already exists".

Thank you in advance for your time and for developing this tool.

Hi, could you include the log on the command prompt when running rmview -v (verbose option)? Also relevant: are you on RM1 or RM2? If RM2: do you have rm2fb enabled? It is known to interfere with the screen sharing (on the tablet side, nothing that rmview can fix by itself).

Hi, I am on RM1.

Here is the log:

Ah that's new! What seems to be happening is that the file /etc/remarkable.conf on your tablet has two entries for the same wifi network. The parser that rmview uses to find your userId for authentication is choking on the duplicate entry. One workaround is to manually amend the offending entries in /etc/remarkable.conf (you can ssh on the tablet and edit the file with any editor eg. vi). Make a backup just in case.

I will update rmview to use a more lax parser of the configuration, which would allow you to use rmview even with the duplicate entries (if indeed this is the only problem here).

Hi bordaigorl, Thank you! This fixed the issue and now it works quite well!
