Finally AttoDuino connected with Linux? Sometimes, yes!

As I wrote back im May 2015, I couldn’t connect to AttoDuino using Linux (AttoDuino Getting started). In the past months I browsed the internet a lot, but without finding anything helpful. As it seems the Bluetooth stack’ documentation can be improved a lot …

So a sat again on my laptop and tried my luck again. After reconsidering the steps in my old post, I turned Bluetooth on and tried this command as root (address and channel I knew through bluetoothctl and sdptool search SP):

# rfcomm connect /dev/rfcomm0 00:04:3E:08:7B:69 1
^^^^^^^ ^^^^^^^^^^^^ ^^^^^^^^^^^^^^^^^ ^
command    device    bluetooth address channel

In return I go this on my screen:

Connected /dev/rfcomm0 to 00:04:3E:08:7B:69 on channel 1
Press CTRL-C for hangup

Well I thought that looked promising, no errors and such!

SMT soldering

I have been an electronics enthusiast for ages now. I had a long period of only repairing stuff and soldering the odd circuit, when I couldn’t find a ready-to-go product. The availability of microcontroller boards got me involved in soldering again, but as I grew older, the parts became smaller. Soldering SMT isn’t that easy without a proper soldering station and although I could afford buying a professional one, I started to search the internet for some ideas for a Do-It-Yourself one.

I was happily surpised when I found Martin Kumm’s post and realised that this could be what I was thinking of. Martin had a kit with the needed parts, which I bought right away. Continue reading DIY SMT soldering station
