Mattias Buelens 72aac552ef Cooja: Track CFS file size
Previously, the Cooja mote assumed that its file was always initially empty (file.endptr == 0). Therefore, a file uploaded to a mote's CFS could never be read by the mote, as the mote would prevent reads from going past the EOF (indicated by endptr).

By tracking the file size and making it accessible to Cooja, the correct size of the uploaded file can be reported to the mote and allow it to read the uploaded file.

Oliver Schmidt a3dba2e25c Changed Apple II 800kB floppy image type.
The .2mg image format contains a header which is missing from our file. So our file is rather a .po image.

I opted to not add the .2mg header as it is only necessary if the metadata it contains differs from the values "guessed" when using the "naked" .po image format. On the other hand there are image file consumers not understanding the .2mg image format.

Oliver Schmidt 1493648fab Removed obsolete apps from retro distribution.
- By end of Jan 2014 SuperTweet.net was shut down (http://supertweetnews.140plus.com/). So Breadbox64 has come to an end for sure :-(

- The email app - or rather email sending app as it is SMTP only - can't be used anymore since nowadays everybody uses some "strong" authentication for SMTP session logon (thanks NSA).

- The ftp client app isn't very useful as it supports only download - for which the WGET app is almost always more useful for. But more important it doesn't support PASV which is more or less the only supported mode nowadays (especially over NAT).

Timofei Istomin eb4bdde9ca Finish the transmission at the end of a correct packet
This patch restores the original behaviour of Cooja when
the transmitted packet is correct (which is true in a vast majority
of cases).

In case of a wrong outgoing packet (wrong length, wrong preamble)
the transmission will end when the radio changes its state (which
should always happen after transmitting a packet).

Benchmarks with RPL (33 runs, 50 nodes, 3 hours of simulated time each)
yield the same results (PDR, delay, number of transmitted packets)
as with the unmodified Cooja.

Timofei Istomin 034a97eed2 Don't generate a zero-length packet in case of errors.
The packet converter used to generate packets of length zero
when it encountered errors during conversion. This caused
exceptions in packet analyzers.

Now the converter returns null in case of error. Appropriate
checks have been added to the code that uses the return value.

Adam Dunkels fb64e64ae2 Java code to let Cooja connect to a serial port 2015-05-10 10:51:12 +02:00
Timofei Istomin eae25d622d Check the frame preamble and MPDU length before parsing
Due to errors in mspsim and/or radio drivers, packets of incorrect
length are sometimes transmitted. The length might be larger than
the 127-byte maximum (considered negative in the current code)
or not matching the actual number of transmitted bytes.
This leads to wrong packet delimiting when converting from
the mspsim-level stream of bytes to Cooja-level packets
causing unhandled exceptions that terminate the simulation.

This patch checks the frame preamble (0000007A) and the length field.
If they are wrong, no decoding attempt is done.

The transmitted bytes are still delivered to the receivers untouched.
The connection is terminated when the radio state is changed (which alway
s happens when TX is done).

Atis Elsts 67427b9b86 Improve multichannel support for Cooja.
* Fix CCA detection in Cooja in the case when the receiver swicthes on the right channel during an ongoing transmission. Always add a connection on transmission, even when the channel is not correct. Initially the connection is in a dormant state; this mimics what Cooja is doing when the receiver radio is turned off;
when the receiver is turned on and switched to the right channel, `updateSignalStrengths()` is called, and the connection starts to recieve PHY-level traffic.

* Add "channel" property for DGRM edges.

* Avoid cross-channel interference on DGRM and MRM radio mediums
