My Slim 2AA Battery Node

wergeld

@siod
Is there any obstruction between the nodes and the gateway? Trees, walls, etc? Depending on what is in between the radios you can dramatically lose signal.

siod

each one goes around a corner and so one wall is partly between the nodes and the gateway and it´s not even concrete. I have one node in my basement attached to an arduino nano and I have no range problems...

The batteries are all fully loaded.

edit:
I would like to post my Node sketch as well as my gateway sketch and MyConfig.h. Maybe there is some optimization potential:

 * This is achieved by having a counter stored in EEPROM which decrements when suspicious activity is detected.
 * If the counter reaches 0, node will not work anymore and will transmit a @ref I_LOCKED message to the
 * gateway/controller with 30m intervals. Payload is a string with a reason for the locking.
 * The string is abbreviated to accomodate a signature. The following abbreviations exist at the moment:
 * - LDB (Locked During Boot)
 * - TMNR (Too Many Nonce Requests)
 * - TMFV (Too Many Failed Verifications)
 *
 * Typically, the counter only decrements when suspicious activity happens in a row.
 * It is reset if legit traffic is present.

 * Examples of malicious activity are:
 * - Repeatedly incorrectly checksummed OTA firmware
 * - Repeated requests for signing nonces without properly signed messages arriving
 * - Repeatedly failed signature verifications
 *
 * If counter reaches zero, node locks down and EEPROM has to be erased/reset to reactivate node.
 * Node can also be unlocked by grounding a pin (see @ref MY_NODE_UNLOCK_PIN).

and so on...

edit: I restarted my gateway and the nodes, it is working for a while, but after 1 or 2 days 1 or more nodes freeze. Does anybody else have equal problems?

carleki

I have ordered the 2.0 boards, they are on their way to my home :)

I'm plannign to use them as :

temperature node
door sensor

For the door sensor, can you tell me if I'm good :
I have to use a 1MOhm resistor between the pin of atmega and one wire of the reed switch ? So I will have the longest battery life (my atmegas are burned at 1 Mhz or 8 Mhz)

Am I right ?

@carmelo42
Thanks for your support by ordering. I actually recieved another 50+ share credit transfer from DirtyPCBs today. It'll be donated to MySensors right away.

If you look at post 116 you'll see the I used a 10Mohm pull-up between Vcc and atmega input pin. Reed switch connects between Gnd and input pin.

Thanks to you for providing us theses files :)

Ok, my mistake (I juste received my 10 MOhm resistor ;)
Perfect, I just have to wait now for the little yellow packet ;)

carleki

I have received yesterday my little packet from DirtyPCB :)
11 PCBs, so 33 sensors :)

I'm just wondering where the C5 capactior will go on the board .. Can't figure out :(

jeti

@carmelo42: maybe this helps, all Cs and the R assembled!

ups... C5 is also not there on my board,it shoud be parallel to C4!

is your sensor working without C5 ?

carleki

@m26872 is it possible to send the sketch in the atmega on board ? using an FTDI serial/usb ?

jeti

@carmelo42 yes

@jeti said:

@carmelo42 yes

I have this serial/usb adapter :

Can you tell me how I connect it to my node ? (noob question I guess ... but I don't want to burn my node :( )

I have found the answer myself with the schematic ;)

Have you ever tried to power the node with 1 x CR2032 battery ?

I have tried, but the node doesn't send anything further than 5 meters ...

siod

I would like to know if your nodes are working all fine. I have the problem that my nodes freeze after a day or sometimes after a week.

carleki

@siod my temperature nodes work good, but my relay one doesn't work :'(

Do you have any logs when it freezes ?

siod

@carmelo42 no, unfortunately I don´t have any logs, any idea how to create logs?

carleki

@siod said:

maybe if you keep your node connected to your computer with USB to serial adapter ?

siod

mmh, no, that would mean I would have to run my computer for maybe 2 weeks 24/7...

I guess it has somehting to do with the sleep function, the device seems to nat wake up after a while for some reason

dpressle

So i got the boards and build them and they work perfect.

One thing i couldn't figure out is why do i get relatively high current consumption, when the node is sleeping i get 1.5mA and not 5.8uA as in mentioned in this post.

I use 8MHz internal clock and the sleep function and nothing is connected to the node.

Can someone help?

AWI

@dpressle Can you post the sketch?
