Hi all
I’m following tutorial [https://github.com/mangOH/ArduinoBridge](https://github.com/mangOH/ArduinoBridge) to communicate MangoH with Arduino.
In step to update:AV\_URL, AV\_PASSWORD
#define AV\_URL “” // replace with url of your airvantage accounr
#define AV\_PASSWORD “” // you can change this here and make it the same as the one on application model
I don’t know what is AV\_PASSWORD and where can I get this info. So could you please help me on this.
Thanks

It could be the application password in Air Vantage. See the post below from David:

> Hi YK, login to airvantage Select Monitor \> Systems from the drop-down menu Click on your system name In the top right, click More \> Edit Under “Application” you should see the name of the application model for the application you are trying to run. Next to the application, there is a lock icon. If you click that icon, you will be prompted with a dialog that will allow you to either view or set the password. If you don’t have the application model registered with that device record in AirVan…

Thanks Wavefront\_yk
I have 1 more question. I tried to run sketch file in tutorial but nothing is returned in Serial Monitor. If I remove Bridge.begin(115200) I saw sensor data is displayed.
So seem that is problem with Bridge .begin() fucntion now?

Hello,
I’m also having difficulties with the Bridge.begin(115200); command seemingly hanging up the Arduino sketch.
I’ve tried implementing the PR changes mentioned here : [https://github.com/arduino/Arduino/pull/2353](https://github.com/arduino/Arduino/pull/2353)
I’ve also tried using older versions of the Bridge library, but nothing so far has allowed the Bridge to start.
Any suggestions?
Thanks,
Max

Hi mxwid
Seem that is issue with Arduino and don’t have any fix for now.
So you can change to use USB connection between Arduino and WP. It will help you communicate between 2 chip.
Thanks
