Sensebender Micro

[Anticimex]

Well, if you think the signing implementation cause initial radio transmissions to fail I am afraid I will need your help in explaining how. Because I fail to see any connection between signing and radio behaviour. st=fail is a transmission problem, and signing implementation require flawless transmissions. I also suspect you both use nrf24 and I also suspect you will not see this if you use rfm69 although I use nrf24 myself for testing and I have not seen what you report. But I am sure you really experience this strange behaviour. But I maintain that it is due to some startup problems of the radio. I am afraid I cannot find anything I can change in the signing codebase to have an influence on st=ok or st=fail. But I am all ears to suggestions of course if you see something suspicious.

@Anticimex Interesting observation - another node with the same rf24l01+ radio from the sensebender with the same GW and signing works without st=fail. This is now clear that this is not a rf24l01+ hardware issue.

[Anticimex]

@alexsh1 Indeed. And also that it is not a signing issue since I take it you use the same FW?
I still think it is a HW issue. You have a new node, right? So the radio has a new power source?

Yes, I tried to compare apples with apples:

1. it is the same distance / FW
2. the code is different to the expend that the sensebender has got Si7021/ATSHA204a and the other sensor did not. I may try to upload a simplified code to the sensebender just to test it to make it a more equal comparison.
3. the power source is the same - 5V 500mA via AMS1117 + cap

[Anticimex]

@alexsh1 You could also try soft signing on the sensebender and see if that makes a difference. Perhaps the atsha device interferes with the radio (this depends on routing and such things). I have no sensebender myself and I have not noticed the behavior you describe with nrf24 and atsha204a.

[alexsh1]

@Anticimex I tried the sensebender with soft singing - still the same st=fail

[Anticimex]

@alexsh1 Ok. I guess that is "good news for me" as it rules out signing related hardware as well. I guess so far, the only conclusion is that rf performance is to some extent degraded on the sensebender.

[Yveaux]

@alexsh1 just a hunch: do both nodes have identical CPU's & clock frequency?

[alexsh1]

@Yveaux Correct - I have used Pro Mini 3.3V 8Mhz which corresponds to the sensebender

[ximinez]

Is there a "pre setup" available yet? The failed transmits are before sensor values are transmitted, so they aren't in the actual sketch but somewhere in the library. I'd like to try just sleeping the sensor 5-10 seconds before the initial data is transmitted and see if that makes a difference.

[alexsh1]

@Anticimex Yeah it seems like a combination of things but not a signing problem

[Anticimex]

@ximinez not sure. I know it has been discussed. But you can always patch the library to test.

[alexsh1]

@ximinez I do not think so. Either to patch the library or you do it in the sketch. Unless I do not know some other secret place.

@ximinez

You can add a before()-method.

It's that easy? I'll give it a try when I get around to it, unless @alexsh1 feels like trying it first :)

Hi! I have just gotten four Sensebenders and was hoping to connect PIRs to them and powering them with AA batteries. I understand from the forums that people do this. But is there a working Arduino sketch example implementing a PIR for wake-up out there? (And perhaps there is a more detailed description for such a hardware setup for us newbies?)

[tomkxy]

I have bought another couple of sensebenders.
I am not able to upload sketches to one of them.
When I connect the programmer the status led goes to solid red. From another one, I realized that it is not solid red.

What is the meaning of a solid red status LED?

[hek]

What does the log say when you upload?

[alexsh1]

@Haakon Have a look here - https://forum.mysensors.org/topic/2478/slim-cr123a-2aa-battery-node
Just change your board for sensebender.

I have Sensebender selected as board.

Btw, where is the hardware folder? It is not present anymore in the development branch?
