@cesar-herrera Can you staate which update channel and if 16.04 or 20.04. Now both are being used it makes it harder to sort issues if OS version is not mentioned. Thanks.

@cesar-herrera give it a few more days and see if it keeps working as it should. Maybe don't apply the daily updates, maybe rebooting that often resets something making it always work.

@cesar-herrera I have done another check in RC and it fails me again. Everything remains the same. I don't know if it's my car.

@cesar-herrera
What device ? Is your UT up to date ?

@cesar-herrera
Yes bluetooth.
What i didn't test on my Cactus is if BT link works for calls.

But again i don't have the same device, and car may have different systems too.

@cesar-herrera
Bluetooth works well on my phone (Asus Zenfone Max Pro M1). The file /etc/bluetooth/main.conf looks like this:

Maybe it will help you.

@aloys
No really on the PC.
But if that's what OP meant there is also possibility using SSH or even directly in the terminal of the device...

@jonius Ok! I only need a respberryPi, the PiPhone kit and to learn programming/porting x.D 😞

@andromeda Thanks.

@thepeter Thanks.

I know it is a difficult thing. But it is not the app who has to read something but are you who has to learn to draw letters in a way the app understands. I see that are many things more important. Thanks.

@wgarcia I've tried to download the map of Spain, and there was an error. It was from jul 2015. I had a copy in a disk and I have used it. I have been able to follow a route from my home to anoher. Perhaps there is a problem downloading a map (not sure). The map is very old, but the size of the directory of spain is 983.5 MB. Very litle. However the app crashes frecuently. There is a lib: libosmscout. This app uses it. The explanation is in http://wiki.openstreetmap.org/wiki/Libosmscout, but I don't know how to create the maps. The files that gives openstreetmap are *.osm and *.osm.pbf. With them you can make the map for OSMScout.

Cesar,

Now that you're able to get an error msg I strongly suggest to look on google : https://encrypted.google.com/search?hl=en&q=Failed to pair%3A org.bluez.Error.AuthenticationFailed

You're problem might be linked to a driver bug, but i doubt is linked to ubuntu touch itself, even ubuntu.
Good luck
