16  Products / Arduino Yún / Re: Console.print(ln): when does this return? on: July 23, 2014, 05:13:51 am
My experience is, that if nothing is connected to that USB, the write buffer fills up and a next write call blocks forever (what else could it do?)

kind regards,

Souns good because the only alternative now is jamvm; although its a fine 1.5 JVM (which is officially long dead), it has to run with 'classpath', the GNU version of the core classes and they are only up to version 1.4 and has lots of bugs. The only plus side is that it runs 'BeanShell'; it makes the entire Yun much more accessible through Java. I can hardly wait until an 'official' Oracle Java implementation for the MIPS processor sees the light ;-) Thanks for the information.

Python is like that: it is extremely picky on indentation of your code; line #24 clearly shows the extra indentation; perhaps it's a combination of tabs and spaces? You won't see it in your edItor but Python does ;-)

Your shield has the same SIM900 chip as I have; I can't power it from an Arduino (it takes up to 2.5A at 5V when it is transmitting or receiving); can't you power it externally? b.t.w. a SoftSerial interface should work fine for RX/TX.

kind regards,

I own a SIM900 chip and I simply hook it up to the usb host port on the Linux side (through usb/serial converter); I can write my AT commands to /dev/ttyUSB0 ...

Frederico, do you know the new serial number of the Yun's with the upgrade in them already?  Is it possible I have one, or do I need to upgrade, just got it a couple weeks ago.

Dean

If it is present in the new release, check the reease date in file /etc/arduino/linino-arduino-release.

kind regards,

The Yun doesn't have that many layers; it's MS Windows 8 that is to blame; it doesn't allow your laptop to connect over an open WiFi network, but it allows a connection over the wire (which makes that entire 'protection mechanism' (mind the quotes) futile). Check if you can reach Yun's webpage with your browser: http://192.168.x.x; I bet you can.

kind regards,

If you have access an other laptop, should give it try.
...
find out which one is trouble maker, Windows or Yun.

Assuming it's a fresh Yun (or with a properly reset WiFi), my guess is MS Windows 8 is the trouble maker; if it's true that it doesn't want to connect to an open network, I find it preposterous.

Jos, when I hover over the bars/shield  I don't get anything other than "Security: Unsecured" and "Type 802.11n"  I presume that a Yun at level 802.11n is compatible with my MiFi/laptop at 802.11g?  

That's no problem; your laptop even noticed that Yun's network is 'open', i.e. no WPA or WEP key are necessary. Can you right click on that network and see all it properties?

kind regards,

Jos

Thanks, but if Ethernet means a wired connection then it's a no go.  This application has to be wireless.

Nobody mentioned anything about wires ...

26  Products / Arduino Yún / Re: Arduino Yun and WiFi - need help getting started on: June 09, 2014, 09:21:38 am
When it shows the list of Networks, the MiFi shows the signal strength bars, and the Yun shows the same signal strength bars but with a little shield with a ! in the shield above the bars.  Is that an indicator?  This is on Windows 8.0.

I don't run MS Windows 8, but that shield icon must be there for some reason; does any text pop up when you hover over it? Can you right-click on the network line and get its properties?

kind regards,

Jos

When you're working with Yun's own wifi, your mifi router or whatever other thing is around you has nothing to do with you. It's only your laptop and your yun

That's the reason why I suggested to switch the entire thing off; I don't believe that a fresh out of th e box Yun (or decently reset) can cause so much trouble; it has to have something to do with the laptop.

kind regards,

On my work laptop I got different responses when I ping'ed.  Usually just a "general failure" or "Request Timed Out", but one time I got a "Destination Host Unreachable" 3 times, then a "Request Timed Out" the 4th time.  It doesn't seem to matter if I've got my MiFi connected or not.

That's one of the lower OSI layers, i.e. depending on, say, humidity, the radio transmission/receiving layer might be goofy; it has nothing to do with your problem.

At my work laptop with the MiFi off I did a diagnostic on the Connection and got a message that said: "Wireless Network Connection" doesn't have a valid IP configuration. It also said that my laptop had a proper configuration.  It also said it detected my Yun.   

Hm, to me it looks like your company is trying to block other networks from being connected; what should be invalid about the IPv4 192.168.240.1? If this happened to me I'd feel the irresistable urge to completely reinstall the OS on that laptop; but your company probably wouldn't like it ;-)

kind regards,

A silly idea: after the Yun has booted, switch off your 'Mifi' network/router; now it's only your laptop and that Yun network with the Yun itself as an access point; can you connect to it now? If so, switch on your router again and see if the connection stays alive.

kind regards,

Jos
