Android: auto connect to Bluetooth speakers

I have two bluetooth speakers at home. One is a Jawbone Jambox and also a Creative D100. The Jambox speaker looks for a bluetooth device when I switch it on that makes connecting a synch but the D100 does not. That necessitates clicking the Bluetooth Android notification and tapping the D100 device to connect. A small inconvenience I grant you but one nonetheless.

This is where Bluetooth Auto Connect comes in. As the name suggests, this app automatically connects to other bluetooth devices. After installing it I selected the Creative D100 so that device will auto connect. When both speakers are switched on it connects to the Jambox which is fine by me. The D100 now connects whenever I switch bluetooth on!

Finally, I wanted to enable bluetooth if I fired up Podkicker to listen to some podcasts but only if I was at home. Llama Profiles to the rescue! I created a new event that checks if Podkicker is running, if wifi is connected to my home network and the phone is charging. If all conditions are true then it enables bluetooth. Bluetooth then connects to whichever speaker is active and I get nice pleasant wireless sound.

It might be a pain if I’m downstairs and my speakers were on in my office upstairs but that’ll teach me not to waste electricity while I’m afk won’t it? If I ever get an NFC tag I could do something with that and my Nexus 7 to do something similar but more localised!

Mac OS X Leopard and Nokia N73 Bluetooth Problems

When I got my new Macbook a few weeks back I thought I could use the Bluetooth functions to browse and copy files from my Nokia N73. It worked just fine on my previous Macbook, an old 2 year old machine destroyed by a cup of tea, so I wasn’t expecting any problems.

Unfortunately it seems that Mac OS X Leopard and the latest firmware of the Nokia N73 just do not like each other. No matter what I did, I could not get the Macbook and N73 to pair. The configuration tool stopped every single time on the “getting more information” part of the wizard. I’m not the only one experiencing problems. There’s a long thread on the Apple website. Both Apple and Nokia have been informed and are aware of the problem but I suspect it’s something in Nokia’s latest N73 firmware.

I have a card reader, now to find the SD sleeve that came with my Sony Ericsson phone. Nokia didn’t include one with their phone.

PS. does anyone else find the keyboard of their Macbook isn’t as responsive as it should be? I have to really hit the y and Enter keys to make sure. It is very annoying!

Linux to Symbian File Transfer – HOWTO

I finally got to see my phone’s filesystem from Linux this morning! I used p3nfs to connect my Nokia 7650 and Red Hat 9 Linux box. Here’s how.

  • Login to your Linux box as root.
  • Make sure you have the following rpms installed: bluez-libs-devel, bluez-libs, bluez-utils. They’re available from your local apt-rpm repository (just apt-get install them!) or from http://bluez.sf.net
  • Copy the following lines to your /etc/modules.conf
    # bluetooth stuff
    alias net-pf-31 bluez
    alias bt-proto-0 l2cap
    alias bt-proto-2 sco
    alias bt-proto-3 rfcomm

  • Start Bluetooth services: /etc/init.d/bluetooth start
  • Create the bluetooth device if it doesn’t exist: mknod /dev/rfcomm0 c 216 0
  • Create a directory for the mobile to be mounted on: mkdir /mnt/psion
  • Download p3nfs from the site above. Copy the nfsapp for your phone to your phone (you’ll have to mail it to your phone, wap, or bluetooth in Windows.)
  • p3nfsd doesn’t compile on Red Hat 9, but it’s simple to fix that. cd into the nfsd directory, edit “mp_mount.c” and remove any mention of extern int errno from it and add #include <errno.h> at the top of the file. Do the same in “mp_xmit.c” and compile using make clean;make
  • Follow the instructions in README.bluetooth.linux (find the BDADDR, bind to the device, and start the nfs app and servers.
  • cd into /mnt/psion and look around your phone!

This is in fact more useful than the Windows tools I have. I couldn’t send images from my phone to my desktop software, and there’s quite a few of them. Using this, I simply went into /mnt/psion/C:/Nokia/Images/ and “mv”ed the files onto my PC!
There’s an “Installs” directory there too so I presume that’s where the .sis and .jar files go to install applications. Will test later. /me’s happy!
This howto wouldn’t have been possible without the invaluable page Tom wrote about his own experiences. Thanks! And of course Google helped me compile p3nfsd!
