Using LibreOffice 18.104.22.168 on Windows 7, Impress Remote will not connect over Bluetooth or Wifi, either from my phone (Nexus 5) or my tablet (Samsung Galaxy Note 10.1).
It used to work perfectly with LibreOffice 4, and I've never been able to make it work with LibreOffice 5.
Is it a know issue ? I could not find any indication on that anywhere.
I have the same problem.
-the smartphone is correctly paired with the OS
-The Impress remote app on the smartphone see the computer but fail to connect (bluetooth / wifi)
-Same computer (Asus G73Sw), same smartphone (GT-I9305 / official Samsung Kikat).
-Was working with Impress (4.x) / Win 7 x64.
-Doesn't work anymore with Impress 22.214.171.124 (x64) / Windows 10 x64.
I will soon make an other test with my firewall (Comodo) uninstalled, just in case of.
When googling the problem, i found few but recent occurrences of this problem, all with LO 5.
Summary -> (mention Impress Remote)
Just to add a few more thoughts: a working bluetooth connection can be established in my case (i.e. between my Linux laptop/desktop and a Nexus 4) -- but the LibreOffice Impress remote control app is unable to 'connect' (whatever it is trying to do) to function. The 'wifi' side of this app works fine for me.
I believe that I am using a new enough version (5+) of LibreOffice that any incompatibilities between it and BlueZ were already ironed out. Nevertheless, it does not work -- and it would be so great if it did!
Same problem on Android 6.0.1 CM 13.1.2 with LibreOffice Impress version 1:5.2.2-0ubuntu2
Perhaps build of latest version fixes this? See https://gerrit.libreoffice.org/gitweb?p=impress_remote.git;a=summary
I have also had similar problems, but unlike other comments, only the bluetooth connection fails (the connection via WiFi works fine).
I honestly could not express exactly when it happens, since I stopped using Impress Remote during the holidays and only now to practice a presentation, I noticed that simply the connection via bluetooth doesn't work.
I did several tests with the following devices and software versions:
Samsung Galaxy Tab 7' (Android 4.2.2)
Samsung Galaxy Ace J1 (Android 5.1.1)
HP x360 (Solus OS 3 Budgie & Windows 10)
Acer E111 (Fedora Workstation 27)
Impress Remote for Android 2.2.3 v17 & 126.96.36.199 v19 beta
LO 5.4.4 (Windows 10), LO 188.8.131.52 (Solus), LO 184.108.40.206 (fedora)
LibreOfficeDev 220.127.116.11 alpha0+ build facfc2951ea9f4745edd4a6fb1cf97697f33f40a
In all cases the bluetooth connection worked properly, being able to transfer files or exchange audio devices, however, when trying to connect LO with Impress Remote it failed.
Fixed with https://cgit.freedesktop.org/libreoffice/core/commit/?id=fb5f13671c50f7f84d654a779bc0ff07e31ce95e
Hi Samuel and thanks for the proposed fix,
I had big hopes when updating LibreOffice today but unfortunately it still does not work for me using LibreOffice 18.104.22.168 x64 (which includes your fix as far as I know) on Win7, with Impress Remote 2.2.3 or 2.3.0b.
The connection fails immediately on Bluetooth and Wifi.
If I attempt a connection via Wifi when the ports are closed on the computer, the app spins and fails after a few seconds. If during that time I open the ports, it fails immediately after.
If there is anything I can do to help you find out what the problem is (maybe there is a log file somewhere?) feel free to let me know.
I asked the author of the patch (I didn't author it) and here's the answer:
"There is updated version of android app that has this problem fixed. Unfortunately it does not show slides preview and is not released yet."
Closing this again, the problem in LO is fixed.
I apologize, but this all is rather unclear.
The patch is against Libreoffice (the PC application) or the Impress Remote (the Android application). It seems to be against the former. If the problem is in the Libreoffice application, seems weird that a new version of the latter fixes the issue.
Incidentally, for me it is evidently the LibO part that cannot talk to the bluetooth stack in my PC as per bug 120663.
To summarize: when I run impress (now 22.214.171.124) it tries to talk to the bluetooth stack and fails, leaving me with a
RFCOMM server failed for LibreOffice Impress Remote: rfcomm_bind: Address already in use (98)
in the system log.
