Since the last post here (it was a long time ago :-) too much work was done, but ERTM isn’t fully implemented yet. So, what did I do last month? I’ll explain each of the features I implemented on the next paragraphs, but if this are boring for you just take a look at the [...]
I spent the last weeks work on my Google Summer of Code project. Code for items 1, 2 and 3 of the roadmap that I posted here[1] 3 week ago is almost done and in process to be merged into bluetooth-testing. Now I’m starting to work on item 4. First I’ll will look to support [...]
I was looking for a pastebin plugin for vim. I’ve found one[1], but it was not working, then I fixed it. The plugin is here[2]. And if is useful to you there is a git repo[3] too. How to use: Put it into ~/.vim/plugin to autoload the plugin every time you open VIM. You can also [...]
I spent the last days studying how Enhanced Retransmission Mode(ERTM) should be implemented on L2CAP. Marcel recommended me to look at TCP[0] code. ERTM on L2CAP is very similar to TCP. Both have retransmission support, recovery error, acknowledgment of packets and timers. That means that ERTM implementation will look like TCP implementation[1] on Linux. So, [...]
The first patch, that add support to L2CAP Enhanced Retransmission, was merged into bluetooth-testing yesterday. The patch adds support to configure L2CAP connections in Enhanced Retransmission(ERTM) and Streaming Modes besides the Basic Mode. Streaming Mode will not be implemented now, but it’s better make all configuration code for the 3 modes instead only ERTM and [...]
Durante a décima edição do Fórum Internacional do Software Livre [0] em Porto Alegre – RS, Brasil participei da Arena de Programação do evento. O desafio desse ano foi implementar um servidor e um cache DNS que suportasse o DNSCurve[1], protocolo de criptografia para DNS criado por Daniel J. Bernstein[2], também criador do djbdns[3]. O [...]
I already started to work on my project. Now, I’m studying how to do the configuration negotiation. Today, only L2CAP Basic mode is supported, so the configuration process is too easy, if a the device try to use another mode, BlueZ stack will response that only supports Basic mode. Now with L2CAP Enhanced Retransmission mode(ERTM) [...]
I’m proud to announce I was accepted on Google Summer of Code 2009. Google announced on Monday the students accepted on GSoC 2009. I’m going to hack BlueZ. My project is named “L2CAP Enhanced Retransmission mode support” . My mentors are Luiz Augusto “Vudentz” von Dentz and Marcel Holtmann. The work is on L2CAP layer, [...]
