These are notes on how to talk to the BlueSmirf bluetooth chip. I am trying to talk to a bluetooth chip from my ubuntu box. I have Putty installed, and a Serial to USB cable connected to a FT232R Breakout board. This board is then connected to the bluetooth chip by crossing Tx and Rx pins. The following hardware is used: FT232R Breakout Board BlueSmirf bluetooth I am writing this post because I struggled for about an hour on how to talk to the chip with putty. The solution ended up to be simple. Load putty with baud rate 115200, 8N1. Remember to use 115200, otherwise it will not work. Have I had followed the documentation closely, I would have been able to talk to the bluetooth chip in 5 minutes.

This article is really interesting. Basically, why would we want to invest the time into learning how to code on a specific mobile platform if we could learn how to do it on a generic platform? Read the article: Open Source Solution for multiple mobile platforms

I have been learning vi for the last few months, and in an effort to use it more, I have installed Vimperator on Firefox. It is basically an add-ons that can be installed on Firefox and what it does it that lets you browse a page using vi commands. It is pretty nice, it allows me to browse a page without using the mouse. It gets very addictive actually because you come to a certain point where you even *feel lazy* to grab the mouse to browse the page.... Well, feeling lazy is a bit of an exaggeration... It's more than sometimes I am in the mood to use the mouse, sometimes I would rather keep my fingers on the keyboard. Anyhow, it doesn't work well all the time though... But here is a command I found very useful for copying and pasting 1. / to search for something 2. i to enter carret mode 3. v to enter visual mode 4. move by j,k to select the text 5. y to yank the text 6. ctrl-v to paste later on... that's it !

You should be able to see a listing for your device if you run adb devices . Then execute the following commands. $ adb shell $ su $ cd /data/data/com.android.providers.settings/databases $ sqlite3 settings.db INSERT INTO system (name, value) VALUES ('device_provisioned', 1); .exit $ reboot After reboot: $ adb shell am start -a android.intent.action.MAIN -n com.android.settings/.Settings
