I’m having difficulties with the Arduino Yun because for a project I’m working on, it’s 32u4 doesn’t have sufficiant flash memory and SRAM and the openWRT/linino on the AR9331 isn’t all up to date for managing images (lacking php 5.5).
Pro's, is there a way that bridgeclient.py and it co-programs would be able to use a TCP connection e.g. an ethernet connection instead of the slow UART connection from the 32u4 to the AR9331?
Paul Stoffregens Bridge library (Arduino-side) would be able to communicate over it. So it would be possible to establish a very fast connection. Unfortunately, the linux side of the bridge is something I hardly understand.
Well, just to bad you can't get one. And if they are indeed selling them (once they become more than a mythical unicorn) at the same price as those preview samples, you can get 2 BeagleBone Blacks + 2 Leonardos for less than one Arduino Tre...
I add "BeagleBone Black (if you don't plan to use shield, the 2 PRUs will be easily outperformance typical arduino you could find)"
Well, the BBB is also a different concept than the typical Arduino, running a full Linux (Debian in the Rev.C), with the possibility of a full graphical interface, so a lot of the alleged processing power is used for that overhead...
I've managed to use a teensy 3.1 with a yun. However, that leaves you with the very slow UART-bridge. I wish there were a bridge possible over Ethernet or USB.
Hi all. I know this is an old post but I hope somebody got this working from a Raspberry Pi.
I need a powerful microprocessor that will connect to the Arduino Mega. I am using the Yun now but the on-board wifi and processing power is to limiting. So I am trying to get the Pi working with the Mega using the bridgle library because then I do not have to rewrite my current Yun code.
Did anybody get it working. I followed the steps. I can see the Arduino rx and tx lights flash but the bridge is not started up when the Arduino connects.
I never got it to work. I finally used an ethernet shield on the teensy to connect to the RPi. That however worked well. The downside was that you can't use the nice routines from the bridge library.
I must be missing something small. If I run the sketch on the Uno / Mega I can see in the serial monitor that the code is working. The Arduino is sending the handshake code all the time. I can also see on the Pi side that when I plug the Ardiono in it will run "run-bridge-udev" to set-up getty as root on that port. But that is where it stops. It does not start the bridge.py code. So I am not shure if the Ardiono is loggin in on the port. How can I check to see if there is activity on the port as I can see the Arduino is sending data all the time. It my be a baud rate problem.
Dear jessemonroy650. I am afraid you are wrong. That is the way the bridge is working. All the posts I have read states it works like that. If it does not work like this please explain how does it work ?
If we have a look at the Yun we will see under /dev/ there is a serial device ttyATH0. if I do a cat of that device while we are sending values I get this.
So as we can see the bridge.py code is communicating with the sketch on the ardiono via stdin / stdout logged in as root on the serial device ttyATH0. It sends all the values until it asks for the next batch. Because I did a cat I have routed the stdin / stdout to another device and it can no longer communicate. Then it assumes that the bridge.py code has died, it sends a XXXXX which acording to the scetch is toe shutdown the bridge.py script and it tries to start it again by calling run-bridge. This is what I see on the Raspberry Pie side all the time. So it seems there is something wrong with the stdin / stdout side of things. If I had a serial terminal I would log in on that serial port to see what is going on. It seems that we get the root terminal and I can see that we get a bash shell. But no input from the sketch is reaching the shell on that terminal.

@jfourie,
I'll be back in a few days - when you feel like listening. Please start a new thread. You are now offf topic.

Why are you nasty with me? I want to solve a problem. It is not off topic. Why do you say so and why do you have a nasty attitude towards me? If this is what Arduino stands for then it is not very plesant. If I start a new Thread where should I post it?
