GSoC meet-up at Unicamp

Last Wednesday (March 3rd) we did a talk about Google Summer of Code at Unicamp. The talk was part of the weekly talk about Free Software in the University. It was presented by mentors and students from past GSoCs. We explained how GSoC works and how one can take part on it this year. I’ll [...]

Handsfree Profile into BlueZ and oFono

I’m proud to announce that BlueZ and oFono now support the Handsfree role of the Bluetooth Handsfree profile. This means that your Desktop now can now act like a headset bluetooth and handle calls from your cell phone.  The work was done during the last 2 months here at ProFUSION.
On the BlueZ side a new [...]

Google Open Source team has just published yesterday a set of stats[1] about Google Summer of Code 2009 and Google Summer of Code during the years. The good news is that University of Campinas (Unicamp) is on the second place in number of accepted students to GSoC 2009, with 12 projects.  We also are the [...]

BlueZ: status update into the L2CAP layer

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 roadmap [...]

BlueZ: What I’m doing that I’m not posting here

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 [...]

Vim plugin for pastebin

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 source it [...]

How ERTM will work on BlueZ

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, there [...]

BlueZ: First patch was merged

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 [...]

Arena de Programação do FISL 10

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 [...]

GSoC 2009: Starting code.

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) [...]
