    @tekka Do you have an idea what´s wrong with the code? yesterday i have changed "sleep(UPDATE_INTERVAL);" to "wait(UPDATE_INTERVAL); " but bothing changed. Fota update or software reboot doesnt work.

    Are the fuses and the bootloader options (txt) correct?

      don't you need to reboot to trigger the update?

        Yeah, right! That's the problem! But when I click on "reboot" on myscontroller, the node does not react to any command, i.e. reboot etc.
        is there a function that takes the command from myscontroller and executes it or do I have to implement it myself in the sketch?

          @rafael156 I had a similar problem, my node would stop responding when I tried to reboot it. The problem was in the fuse settings, have you checked if they are all set? What version are you using? (16,8 or 1)

            @rafael156 have you tried with smartsleep instead of sleep? Of course the node would respond only when it wakes up.

              @Soloam i have checked fuse settings several times . i use the 8 mhz version. boards.txt see above .
              at burn process, arduino ide (1.6.13) gave me a warning about the fuses
              which fuses do you have?

              @gohan no, i didnt. but i have tried wait(), with no success. i will try smartsleep() today!

                @rafael156 Hmm, I don't think this is related to the fuse settings. Try again changing sleep() to wait() and upload the full logs from MYSController and the node (with MY_DEBUG enabled)

                  However, I would suggest that the functions "wait()" and "smartsleep()" be mentioned in relation to the MySBootloader in a separate point under "https://www.mysensors.org/about/fota". Maybe under a chapter:

                  1. Enabling FOTA in your sketch

                    1.2 MySBootloader
                    --> ... use smartsleep() and wait() instead of sleep()...

                  • if sensebender gateway is connected via usb, only one instance may access the gateway at a time, therefore "OpenHab" must be terminated first

                  • do not use "sleep()" in the sketches. only "smartsleep()" or "wait()".
                    use the current dev-branch from "https://github.com/mysensors/MySensorsBootloaderRF24

                    However, I would suggest that the functions "wait()" and "smartsleep()" be mentioned in relation to the MySBootloader in a separate point under "https://www.mysensors.org/about/fota". Maybe under a chapter:

                    1. Enabling FOTA in your sketch
                      1.1 DualOptiboot only
                      --> text as before
                      1.2 MySBootloader
                      --> ... use smartsleep() and wait() instead of sleep()...

                    Summary:

                    • fuse settings 8MHz external crystal:

                    • if sensebender gateway is connected via usb, only one instance may access the gateway at a time, therefore "OpenHab" must be terminated first

                    • do not use "sleep()" in the sketches. only "smartsleep()" or "wait()".
                      use the current dev-branch from "https://github.com/mysensors/MySensorsBootloaderRF24

                    @rafael156 said in [SOLVED] MYSBootloader FOTA Update hangs on ProMini-3V-8MHz (reboot problem):

                    // Sleep for a while to save energy
                    //sleep(UPDATE_INTERVAL);
                    wait(UPDATE_INTERVAL);

                    I'd use smartsleep in this case as wait will keep the MCU active and drain battery. Wait is better used in place of "delay"

                      ok, Thanks at all!
                      You helped me find the mistake!
                      it was actually because the node could not receive commands because there was a "sleep()" hidden somewhere in each sketch. after I searched all sketches thoroughly and replaced them with "wait()", everything runs without problems:

                      However, I would suggest that the functions "wait()" and "smartsleep()" be mentioned in relation to the MySBootloader in a separate point under "https://www.mysensors.org/about/fota". Maybe under a chapter:

                      1. Enabling FOTA in your sketch
                        1.1 DualOptiboot only
                        --> text as before
                        1.2 MySBootloader
                        --> ... use smartsleep() and wait() instead of sleep()...

                      Summary:

                      • fuse settings 8MHz external crystal:

                      • if sensebender gateway is connected via usb, only one instance may access the gateway at a time, therefore "OpenHab" must be terminated first

                      • do not use "sleep()" in the sketches. only "smartsleep()" or "wait()".
                        use the current dev-branch from "https://github.com/mysensors/MySensorsBootloaderRF24

                      @rafael156 oh crap ... I put in that lowFuse as FF .. ( I read you had it for 8 MHz INTERNAL .. but nooo you wrote external ... ooops ... is there any way to force write it back without connecting an 8 MHz oscillator to the chip .. I only got 16 MHz oscillators .. or am I screwed for that chip until I go and get one?
