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

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

          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?

              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.

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

                @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

                  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

                    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.

                      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

                      M.C.

                        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:
                        0_1495966865551_upload-48973443-91a2-4504-a73b-96557383d6bf

                        and that´s the error:

                          @siod what board are you using? Windows or Mac?
                          I would suggest update Arduino IDE - you are running an old version

                          Many people experience similar issues when using a wrong version of IDE:

                            I have been using version 1.8.x (at 1.8.2 now) for quite a while now, so no experience with 1.6.10

                            Best is indeed to update the IDE, as this will also bring new versions of GCC (the compiler) and I thought also of AVRDUDE (transfertool). Not sure about that last bit though.

                              Hi guys,

                              thx for your quick reply. I could upload the bootloader using ver 1.6.5 of the Arduino IDE. After that I realized ther is already a 1.8.2 version released which is closing the gaps between arduino.cc and arduino.org.
                              I havent tested this version now, but I guess it was just an IDE error, so everything´s fine now...

                              still learning...

                                I have copy the file over the existing files and then I get this error with burning:

                                java.io.IOException: Cannot run program "{runtime.tools.avrdude.path}/bin/avrdude": CreateProcess error=2, The system cannot find the file specified

                                I am using Arduino IDE 1.8.2

                                  I'm probably a rare case but I successfully burn the bootloader (atmel 328p stand alone with slimeNode board) using atmel studio7 with an AVRMK2ISP, flash the mySensors code using arduino IDE and the "nodeManager" libraries succesfully too and everythings appear properly in my HomeAssistant, very nice, I've just give a paypal tips ;o)

                                  But I have no idea why I use this bootloader ??? If I used a nano, I wont change the bootloader ? Is there something better ? It could look stupid but their is no real explain about WHY I must change my bootloader on this page...

                                    Found these bootloaders and using the 1MHz for some low power experiments. I did get this error message when burning the bootloader (using USBASP programmer) :
                                    "avrdude: WARNING: invalid value for unused bits in fuse "efuse", should be set to 1 according to datasheet
                                    This behaviour is deprecated and will result in an error in future version
                                    You probably want to use 0xfd instead of 0x05 (double check with your datasheet first)."

                                    The bootloader woas succesfully burned so the message was informational. I did look into this and made the following changes in boards.txt :
                                    I changed all the lines containing "......bootloader.extended_fuses="
                                    There are multiples sections in the file that have these lines.

                                    old value -> new value
                                    0x04 0xFC
                                    0x05 0xFD
                                    0x06 0xFE
                                    0x07 0xFF

                                    I used this site link text
                                    for calculating the new values for the extended fuse.
                                    Now the error message is gone. Maybe this is of any help when using these bootloaders.

                                      I can probably package this in a directory structure you could add to the Hardware folder in the Arduino files, but I do not have the time for it right now. I know that has been done for the original Optiboot 6.2 files already (including a pinout file for the various processor variants):
                                      https://github.com/Optiboot/optiboot

                                      For the moment I have added my boards.txt file as I use it in my Arduino IDE (common), it shows some fuse settings, but you are right: a document describing the fuse settings to use, and their effect on a bootloader would be a nice reference for many people.
