Attach antenna to BlueDuino?


#1

Is it possible to attach an antenna to the BlueDuino in order to improve its sensitivity while acting in central mode (i.e. scanning for advertisements from beacons)?


#2

It’s possible. But you need do soldering work with 0402 component. It’s not easy. I will post a photo if you’re interested in it.

Please check the picture.

For add external antenna, follow these steps

  • remove the inductance in red square. re-soldering one side of its to pad A. The inductance change to horizontal status. Be careful! it’s very small
  • soldering external antenna to pad B. A wire 4cm is enough for external antenna

Thanks. Seems like a challenge for my non-technical skills, but I will give it a try once I start using my backup BlueDuino, i.e. I can’t afford to screw up my current running BlueDuino. Haha!

I’m happy to pay for one with the external antenna, but I have some questions for you about this. I will PM you in a few minutes.
