Sensebender Micro
-
How many would be interested in a Sensebender Micro LE (light edition), and how many units would you buy?
The Light edition would be without Si7021, and external flash.
I do not have any prices yet, as we need to have some expected sales figures to give to our partner. We need batch sizes of at least 100 units (preferably larger like 200) otherwise setup fees, etc. would eat away on the savings from removing the components.

I haven't got any numbers from itead, but from the prices that I get from mouser, we could probably save around 4$ if we skip Si7021 and external flash.
This is still more than the cheap mini clones etc. but the problem here, is that we are running in low volume batches. The setup fees for each batch is rather high, and this has to be divided out on each board in the batch.

Ps. Main page at http://www.mysensors.org/hardware/micro still says preorder but when clicking through imall has in stock.

We don't get notifications from itead, when they change the status in their shop.. So we have to check it ourself..

I have mine up and running and MYScontroller sees them.
i'm trying to send and OTA to these devices. but it doesn't seem to be working.@hek can you confirm these came with the correct bootloader to do this? i thought i read in the start of the thread it would.
when i try to send a OTA nothing happens.
anyone have this working that can comment on what needs to be done to get it working?
Thanks!

The OTA->flash requires sketches running library code from the development branch (which it isn't currently). The boards comes preloaded with the correct bootloader that supports moving firmware from flash->program memory at boot-time.
But something must load the flash over-the-air also. This requires that you:
- Compile the sketch using the dev-branch
- Enable MY_OTA_FRIMWARE_FEATURE in MyConfig.h
- Keep node awake
- Call gw.process() in loop-section (which handles the fw-update-commands in the background and resets node when a new firmware has been uploaded).
Now that I have received my board I can actually test this code I wrote a while back:). I hope it won't bee too many bugs in it.
But note that the default temp/hum sketch on these boards sleeps most of the time it wouldn't hear the fw-update requests anyway. It would probably be better to use this feature on boards that always is awake.
For more information on what is actually happening in gw-process you can look at the code that was added in this push:

It's almost too easy to setup a sensor network (for temperature and humidity) now.
solder a socket for the NRF module, a battery holder. Plug in the NRF module, put batteries in, and you have a sensor online. (I have 3 sensebenders from tiead online at the moment, together with 2 prototypes). Need to get some more battery holders, before I can make more sensors now.

I agree! I ordered 4 from the second ITead batch (I let others get their hands on the first batch because I already had a couple OSHPark deployed) and had the first sensor up and running in no time! Great job and contribution to the MySensor's community! :+1: :+1: :+1:

Thanks.. It's actually kind of fun, when I see that things I have created, actually brings value to other people.. Always been a driving force for me (no matter what I have had my hands in, whether it's software of various types,VHF radios for ships, mobile phones, bluetooth headsets, or sensor modules :) )
