Sensebender Micro

@tbowmo

I tried uploading the sensebender sketch using 1.0.5-r2 with board config "pro mini 328 3.3V 8MHz". The si7021 doesn't work in this configuration, but I managed to get a sleep current of ~6.8uA

I can provide the binary output from the two IDE versions if someone can give me an indication where to find the build binaries.

I think it's better if we can get the intermediate asm file from the compiler chain. Will look at it tomorrow evening (I have closed my computer down for the evening today)

I have so far had no problems running my PIR sensors at 3.3v with the following hack.

You can not do this with all PIR Sensors from what I understand, but one of the ones listed in the MySensors store is what I've been using. Go down to the bottom of the article.

I just wanted to follow up and say thanks for the link/info
i was able to get that working.
surprised that they just don't offer a 3v pin.. it works great the way that link shows
Thanks again!

Has anybody built a box for the standard Sensebender Micro with 2 AA batteries yet.
I would like to get the .stl files if so
Thanks Doug

Hi Doug,

@ServiceXP has posted this one: http://forum.mysensors.org/topic/1566/mysensors-sensebender-micro-3dp-case

Has anyone been able to "Include" it to VERA UI7, My Sensebender borad is working fine according to the output from the Arduino terminal window - it request a node id, but will not "include". I'm using the default code already installed in Sensebender Micro board.

Yes, it works in UI7. Are you using the correct Vera-branch?

If somebody is looking for some Sensebenders. They are in sale currently for only 14$

Edit:

I thought I had paid 17$ but they were initially sold for 14$. Sorry.

I just order 4 new sensebender, NRF24L01+ (normal and PA+LNA), and Iboard for the gateway. Shiiping is quite expensive (about 31 $)

[tbowmo]

@Fabien

Did you choose DHL as shipping option?

[soward]

I just tried to order something from them and for some reason DHL is now the only available ( US ) shipping option, and it's quite expensive. The sensorbenders I ordered last month were ~$6 shipping, the other components I looked at today via DHL (similar size) were $46, so might be worth holding off a bit until they restore the air-mail option.

[hek]

$46 in shipping is a bit hefty. I'll check what's up with their air mail shipping.

[soward]

@hek I have seen it happen once before with them -- wait a few hours, or at most a day and it'll be corrected if history repeats...

[Fabien]

My last order have cheap shipping costs. But this time I buy lot of things, and shipping price is probably higher du to the weight.

@gloob You fell for the oldest marketing trick in the world. I also missed a heartbeat when pressing on the clearance banner and seeing sensebender there!!!

[tbowmo]

@Moshe-Livne @gloob

The sensebender is shown under the "new stuff" banner :)

(At least in the email I got from Itead :))

Hi,

@tbowmo or @hek: Could you point me to the right Mysensors bootloader directory please? Is it this one https://github.com/mysensors/Arduino/tree/master/MYSBootloader ? I think yes, but I have seen others links, so I am not sure. I would like to add and test some ulpnode functionalities and would like to start with the right bootloader.

[tbowmo]

@scalz

for the sensebender, we are using DualOptiboot, as we have an external flash onboard, that we can use for OTA firmware updates (it requires dev branch of mysensors though..)

[scalz]

@tbowmo: thank you for your reply. So what is the difference between your link and the one I posted just before (I have not checked yet) ? So, for the moment there is no Mysensors bootloader for stable, isnt it? I just need to add some pin toggle to make some tests (enable dc booster on my board, tune clock, and keep the ota stuff...) and wanted to stick to the stable branch but no problem I will move to dev branch, I think it is time :smiley: .
I don't remember who wanted to use ws2812 in bootloader (maybe it is you?) but there is an implementation in ulpnode bootloader if you are interested : https://github.com/hallard/Arduino-Boards/tree/master/1.0.0/bootloaders/ULPoptiboot

[tbowmo]

@scalz

It's two different bootloaders. the one you have linked to is handling the radio in the bootloader, and can reprogram itself OTA without an external flash attached.

The one I have linked to, is using an external flash (on the sensebender) and by loading the external flash with a new sketch, it will cause the bootloader to load the content of the external flash, into the internal flash. The same concept is used in LowPowerLabs moteino boards.

In order to use dualoptiboot, your sketch needs to support the external flash, and write the firmware it receives OTA to it. This functionality is only available in the dev branch as of now. I don't know if @hek has tested it yet? (I have been busy with a lot of other things lately so haven't got around to test it here..)
