Using a 3g/4g internet connection and two mobile phones

For the fun of it we made an Android app allowing a sender phone and a receiver phone to act as a remote control. The reciever phone is connected to a Polulo Maestro servo card with Usb Host.

It work pretty fine actually.

We use some nice piece of communication software (from another project) enabeling mobilphones to communicate peer to peer bypasing NAT restrictions using no server in between. This software also allow for logical peer identites without any spesific account or setting, just figure a peer name and connect. (so it make it very easy to connect with a standard phone connected to internett with 3g/4g)

Why not use mobilphones for controller directly, it have everything, gps, gyro, accelerometer (+ easy programmable i java) ?

Hi Sven,

Thanks for sharing the info. What platform did you use for video encoding and streaming?

Looked your youtube... Kul!!!

I would like to implement streaming into my test app to see if it works.

The m2 software do pretty mush the same as you did (i suppose) figure the public IP address of the phone. This software is basically designed for the purpose of addressing of peers and to handle NAT when peers are located on a subnets, (The case on most phone networks).

Ref to som explain how it works:

Would you like a cooperation (for fun) ??

Was flying again last weekend. It stiller work. A litte i practical ising the phone screen  'gimbal' intefase,  but with some practice it works and plane are pretty controllable. :)

Shold have a remote controll gimbal inteface to input to phone instead. Easier to controll.
