Connect React native application to my robot with bluetooth
Hello guys,
I'm working on an outdoor robot. For now, the user interacts with the robot as follow :
- Connection to the robot hotspot with your smartphone
- Use the simple Web UI with your browser on your smartphone
To do so, I used the rosbridge_suite package of ROS noetic.
I don't like this way of working because it isn't totally transparent. I like the way your smartphone is always connected to your smart watch transparently using bluetooth. In addition to it, I would like to create a real smartphone application (Android + IOS) instead of a web based application.
So my question is : what is the best way to connect this smartphone application (in react native) to my ROS robot using bluetooth ? Is there some ros package, a bit like rosbridge_suite, to deal with this use case ?
Thanks in advance for your response.
Could you clarify what you mean by "this isn't totally transparent"?
With bluetooth, your smartphone can be connected to several devices in parallel and the reconnection is transparent while with an hotspot you can't be connected to a wifi in the same time and so the user of the smartphone will have to reconnect to the hotspot each time he wants to interact with the robot... I believe it isn't the best user experience.
I'm not sure I necessarily agree, but: easiest would probably be to use Bluetooth to setup a network connection between your robot and your phone. As soon as you have IP working, everything else you already have should also work (ie:
rosbridge, etc).Thanks for your answer ! Can you explain to me why you disagree ? In addition, can you provide a link or a tutorial on how to create this network connection over bluetooth ?
re: tutorial: it's an OS-level configuration task. You're likely to find information on the Ubuntu (or whatever your OS is) documentation site. Same for your mobile device/OS.
