Building XBee network: part 1

Xbees are nice small part used to help small stuff, like Jaluino Bee, communicating together. These are wireless modules, implementing ZigBee protocol. This is quite a tough one, luckily using XBees themselves remains something accessible for the mere mortals. While you could use Bluetooth modules, you may still be interesting in using Xbee as they can join together to build a multi-point network. That is, having several modules talking each others, not just point-to-point communications.

Make a wish to support Jaluino

I made a wish on Seeedstudio’s Wish platform: have Jaluino Bee board manufactured and listed at Seeedstudio, the next big step for this project.

If you want to support Jaluino Bee, vote for this whish, it could come to reality!

Cheers, Seb

Batches underway !

After several month working of Bee improvements, new PCBs for Jaluino Bee v2.1 have been ordered from SeeedStudio. Several other PCBs have been ordered as well: some more Mini-Crumboard, and a new shield, Mini-ProtoGrove. I’ll post more about all of this when I get PCBs and build new Bees. In the mean time, you can have more details in forums and pre-order PCBs:

Troubleshooting SD memory cards

This is a recurrent issue: “my SD card won’t work, I tried the sample, I triple check hardware, it just won’t work”. The main problem here it’s hard to get feedback and report it to jallib library’s author (namely Matt). Different issues were previously found:

  • some brands seem to work better than others. For instance, SanDisk is reported to work nice, whereas there seems to have troubles using Kingston’s.
  • some SD cards will require pull-up resistors, some won’t.
  • and SDHC, high capacity SD card, aren’t supported.
