@Samuel235
Sorry for my english, your answer is ok Tanks you

[Samuel235]

@mar.conte - Its okay, i understood you, just about ;)

Now just apply that description to all of the other bootloader varients that the great @Gertsanders has provided us with :)

Help!!!
I have upload bootloader 8mhz 38k bod 2,7 and internal clock with sketch j gammon!!!
Consumption 2 mh!!!
Why?
Tanks

[Samuel235]

I'm sorry, i don't understand the issue at hand.... Could you attempt to explain any clearer?

@Samuel235
Hy
My project is simple atmega328 with internal clock 8 mhz in powerdown mode end rfm69 hw which send to gateway when pir motion is high powered all with 2 aa battery.
The First test what i do is in breadboard atmega328 with optiboot 6.2 ( i have upload bootloader 8mhz internal , 38vk, bod 2v7) and simple sketch j gammon: result no microampere but around 2/5 mah in sleep mode;

[alexsh1]

@mar.conte I'm not familiar with the sketch you mentioned. The best is to use the voltmeter and oscillograph to determine consumption.

Why do you have BOD 2.7v? I do not have any BOD - this would let a node to run on two batteries until voltage drops to below 1.9V

[mar.conte]

@alexsh1
I have only voltmeter extec, can i mesure ua?
Can you send simple sketch for deep sleep ?

[Samuel235]

@mar.conte - Are you basically saying that your hardware is using too much power to enable you to run on battery for any substantial time?

[mar.conte]

@Samuel235
Yes, i want obtain few micro amp but its two month wich i try without result.....

[tonnerre33]

@mar.conte Which skecth did you use ?
Did you have radio errors in your log ?

[Samuel235]

Could you please either include your sketch here or give us a link to the example sketch that you used please.

[mar.conte]

@Samuel235
Resolved
I have try with sketc j gammon https://www.gammon.com.au/forum/?id=11497
And the problem are pir input (model hrc-501)
Are ever high and the cpu dont go in sleep.
I have remove pir and all ok the atmega run 20 uah very good.
Can you advise a good pir wich run to 3,3 V for my project?
Tanks

[mar.conte]

@mar.conte
im not sure why pir with simple test like this http://playground.arduino.cc/Code/PIRsense is ok
but with my sketch the cpu reset forever

Firstly, i can't read the structure the way you have posted your sketch. You should use the code function in the reply, the icon looks like "</>" above where you make your reply. Put your code in there for us to have any chance of reading it at all.

Secondly, I don't think that this is the place to be posting this issue. For a start, this isn't an issue relevant to the bootloader in this thread and secondly, it doesn't even have anything to do with MySensors.

[alexsh1]

@mar.conte yes, you can measure consumption (should be in uA) while sleeping with a good voltmeter.

However, I really fail to understand what has Nick's sketch you mentioned to do with MySensors? I suppose some people here may be aware of sleeping issues, but again your problem has nothing to do with MySensors.

Please see the following - it may help you troubleshoot your issue
https://www.mysensors.org/build/battery

[mar.conte]

@Samuel235
I wanted to build my projects with mysensors, first of all I started with bootloader found in this section to try them with examples that I know because I do not know yet mysensors, I wanted to learn it so I took the liberty to insert code in your section. if you can figure out my problem thank you or I apologize for the trouble thanks

[Samuel235]

I get why you done it, but i don't understand why. You don't need to 'know' mysensors.... There is a getting started page, i suggest you take a few hours and read through everything. I'm not helping with an issue that is completely not related to mysensors while on the mysensors forum. Just simply for future readers of this thread that come here to solve their issue, if this thread is bloated out with over 10/20 replies that is not related to the question at hand its much harder for them to find their resolution here. I suggest contacting the author of the code himself as i'm pretty sure that your issue is not the bootloader.

[mar.conte]

@Samuel235

Thanks anyway, this section introduced me to some very interesting bootloader, at least with these bootloader I can get a few microamperes for my projects, I will take note of your good day and thank you tips

Hi guys,

I am getting an errror when trying to burn the bootloader, any idea what´s wrong? Im using Arduino IDE 1.6.10 and these settings:
