BlueDUN+

Mirko Solazzi

About this app

This program emulates the hardware modem on your Android phone. It allows your phone to share wifi or mobile connection over the bluetooth channel with other devices like PCs,tablets or navigation systems. The bluetooth DUN (dial-up network) service is turned on, in order to enable the external device to access the Internet.
It supports both TCP and UDP protocols; NO ROOTING NEEDED!!

IMPORTANT NOTE: You can find the app installation package for free on internet; be careful because it includes a spyware code inside!! It sends all your private data to hackers

Tested with Windows Xp / 7 / 8 / 10 PCs, Mercedes Comand OnLine, Toyota Touch&Go / Entune, Tom Tom Go/Rider, Clever GPS, BB Playbook

This "plus" version introduces the following enhancements:
- new implementation of UDP protocol for better supporting the VPN connections, in particular for Mercedes servers
- new option for automatic executing the service after the device restart
- the BlueDUN service is exported for controlling its execution from external applications
- specific port forwarding toward local applications [ allow external devices to access to custom app via TCP/IP over bluetooth]
- enable the local applications to control of external devices via TCP/IP over bluetooth

USAGE NOTEs:
- you need to disable Smart Lock OR define the external bluetooth device as trusted
- for external devices with low transfer speed (i.e. car navigators) probably you need to reduce the BT Queue Length parameter [ from 10 -> 2 ] in the app settings

It doesn't work with some Motorola (Droid) / Sony (Xperia) / HTC devices due to firmware limitations.

Please test the trial version (it includes the same basic connection algorithms) before purchasing and contact me for any issue before writing negative comments; I can also refund you also after the 2 hours of testing period.

How to setup (only the first time):
- Remove the previous pairing between your devices
- Start the BlueDUN service, make the phone discoverable
- Create the new pairing
- Setup the DUN connection on the client device: don't care about phone number, account or dns because the app emulates only the modem behaviour but it sends/retrieves data to/from phone wifi/mobile connection!

In case of connection issues, please enable the "Logger" and "Log to File" options in the setting panel; go back and restart the service, try some connection attempts. Finally click the "Send Log files" option to send an email with generated log files.

I don't provide support if you add negative comment on Google Play before contacting me by email

Ratings and reviews

Just had to say that I had tried everything to pair bluetooth from a Samsung Galaxy Note 8 to Lexus connected services and failed (seems the phone too new for the car, as it doesn't have DUN profile) . BlueDun worked a dream first time, and continues to. I recommend it 100%. Just one question - I have to manually stop the app running on the phone when I leave the car. Is there a way to automate this, or is this correct? Thanks so much for a magical app !

Avoid. No actual support from the developer. It does work occasionally with MB comand, however on android 9 you have to keep the app open and screen unlocked to make it work (sadly not always). As you have to basically keep your phone in your hand - this makes this app useless.

I am very disappointed. I could not make the app work on my LG G8 Think. It never got past turning in the service. Each time I tried to turn it on, it turned off again. Needless to say I could not connect to Mercedes COMAND APS. I wrote to the developer and have had no reply and Google Play did not refund me. Not recommended.
