Yeah the Blue Gecko modules are based on the arm gecko series from Energy Micro who were also, you guessed it, acquired by Silabs. They are event based with excellent IDE/Libs , very low power and about $11 a module rather interesting, they also have a special dev board

Thx Alan,

Interestingly, SiLabs also acquired Telegesis who make the zigbee-Ethernet gateway we've been working with.

Hi Ken,

I agree that a workshop would be good.  The possibilities are endless and your idea looks good.

The other thought is that there are so many platforms to choose from (you mention 2 and I have 4 more on my desk now). People might be interested in an overview to help them decide which to try first. (I'm adding Simblee to my list.)

A further issue is how to build gateways, whether phone or computer-based to provide UI and data transmission.
See my point that I'm not sure what we ought to do in short sessions.

Andrew, Paul,

I have a self-made board with a RFduino SMT module on board - which ought to be up and running by then.  It's an MSP430i2041 based design - which has 4 x 24bit individual ADCs  -intended for 3 phase energy monitoring




The Simblee also looks interesting  - both are Nordic Semiconductor nRF51822 based (as is BBC Microbit).


Might be neat to tie a few of these platforms together during a workshop.

Would be great to have a talk on BLE and maybe a look at it in closer
detail and at a few different platforms?

Best,

Andrew
