[Tinyos-help] BaseStation Mote Changing Serial Port.
Hi list, I have one mote acting as a BaseStation, which randomly changes port (/dev/ttyUSB0-/dev/ttyUSB1), causing SerialForwarder to stop working. Has anyone else had this issue? My packet size is larger than standard, could that be the cause? Or something to do with linux drivers? I'm using tmote sky motes, tinyos-2.1.1, and Ubuntu Lucid.

Re: [Tinyos-help] BaseStation Mote Changing Serial Port.
Hi, I don't think that your problem is related to your packet size but most probably to linux drivers. I have one mote acting as a BaseStation, which randomly changes port (/dev/ttyUSB0-/dev/ttyUSB1) Do you mean that the port changes at runtime or between 2 executions of SerialForwarder ? If the port changes at runtime, I would assume that the USB link gets shortly broken and up again and thus the driver mounts the USB-serial converter on another ttyUSB. There are ways to configure Linux/udev to always mount the same hardware on the same ttyUSB port. I only have a link to a french blog entry I could remember. http://www.lefinnois.net/wp/index.php/2009/04/15/ttyusb0-ttyusb2-non-ttyusb1-grhh-udev/ Basically, you can force udev to mount a device to a fix port based on its serial number. You can retrieve the serial number of your USB converter with: $udevadm info -a -p $(udevadm info -q path -n /dev/ttyUSB0) and then update your /etc/udev/rules.d accordingly. This is only part of the solution (will always mount the serial link on the same ttyUSB port) but it does not explain why the device gets disconnected and connected again... Have a look at the output of dmesg to see if your Linux host really detects disconnects... In case of disconnection you should see something like: [191876.912510] ftdi_sio 2-1.4.1:1.0: device disconnected and later again a connection [191886.215902] usb 2-1.4.1: new full speed USB device using ehci_hcd and address 10 [191886.331193] usb 2-1.4.1: configuration #1 chosen from 1 choice [191886.333078] ftdi_sio 2-1.4.1:1.0: FTDI USB Serial Device converter detected ... [191886.333747] usb 2-1.4.1: FTDI USB Serial Device converter now attached to ttyUSB0 Hope this helps, Romain On Thu, Jun 16, 2011 at 12:27 PM, colum walsh walsh.co...@gmail.com wrote: Hi list, I have one mote acting as a BaseStation, which randomly changes port (/dev/ttyUSB0-/dev/ttyUSB1), causing SerialForwarder to stop working.

Hi Christian,
Please post the code you are using for the test if you can.

Hi Horst,
Are you using the latest version from tinyos-main? You can change the
listen length in RF230RadioP.nc (chips/rf230) with this function:
command uint16_t LowPowerListeningConfig.getListenLength() { return 5; }
For us LPL on IRIS works perfectly fine.
Hi all,
perfectly fine is not the thing i see when using Iris and LPL .)
Even in a simple scenario with 1 sender and 1 host you will see a lot of
packages lost(30% for me).
We had the same thing on Micaz nodes using the the default values for
the CCA check. When increasing the CCA check value to 1600 (~10ms CCA
check), the package loss dropped to 1-2%.
I will do some testing and let you guys know whether i can somehow fix it.

Re: [Tinyos-help] PacketTimeStamp.isValid() mostly returns FALSE
Timestamping has known issues in the default cc2420 stack (telosb, micaz, etc.) under heavy load. Try using the cc2420x stack. Compile with make telosb cc2420x. You'll need the latest sources from google code. Janos On Thu, Jun 16, 2011 at 1:34 PM, Xiaohui Liu whu...@gmail.com wrote: I'm using the default one, I'm not sure how to use cc2420x.

[Tinyos-help] Never get an ACK on Iris motes
Hello, I hope someone out there can help me with this issue because I begin to freak out on this. I wrote a program that makes use of Packet Acknowledgments. While in TosSim everything works nicely, I do never get an ACK for the packets I send with my real Iris motes. The packets do arrive at the other node though and everything is fine but the sending node never gets an ACK. I guess my code is ok since everything is good when using tossim. I also programmed another little test application to see if this was just my programs fault but the new test application does not receive any ACKs, too. Are Iris nodes just not capable of sending/receiving ACKs? Any help or suggestions are very welcome.

Hi Romain,

SerialForwarder may cut out again, but shouldn't fail completely after
adding the following file to /etc/udev:
#tinyos rules

Basically, you can force udev to mount a device to a fix port based on

In case of disconnection you should see something like:

and later again a connection
