I know some people are probably wondering if I'm still alive. I've been in isolation-mode trying to get the shop up (yes...still). It's probably been one of the toughest things I've ever done in my life. However I did have some time to work on the Chibi stack and cleared up a few things that were bothering me. One of them was some nasty frame loss when multiple frames come in closely spaced. This would occur if you did something like broadcast a request to multiple nodes and they all returned a response simultaneously. Only one of those frames would get through and the rest would get lost. The current release fixes that so you should be able to receive multiple frames simultaneously with no loss up to the maximum size of the receive buffer which you can configure in the code
I added version numbering rather than just using release dates for reference. Version numbers are much more intuitive. You'll also find support for the ATMega32U4/AT86RF212 combination. I'm actually making a Chibi 900MHz board and needed this for testing. I'm really enjoying working with 900 MHz because the range is better and there is less attenuation through objects. However I'm still a fan of 2.4 GHz just for the variety of available chips, antennas, front ends, and modules to interoperate with.
You probably won't hear much from me until the shop is up because I really need to get that out of the way so I can continue with all of my other projects. Multi-tasking that with everything else was just not working. So much has gone on in the past few months that I do have quite a bit of material to post and topics to talk about. Hopefully that should all fall in place after things settle down. In the meantime, check out the latest Chibi software:

All the best for your endaveour. I am myself a gr8 fan of 2.4 GHz data-link but when it comes to critical filed application, redundancy must me integrated into the system. I recommend use of 433MHz system as a fail-safe to 2.4GHz data-link. MMIC design is my key expertise but I have also developed High Power RF Modules and systems for various 2.4 GHz systems ( Nordic, Jennic, TI, Ember, Radio Pulse and Atmel). Recently I started offering consulting & outsourcing services (www.rftrinity.com) for various wireless applications upto 10GHz. Should you have any queries or business opportunity, please do not hesitate to contact me via email ([email protected]) or on my mobile (+91-986-086-3334).
