[SOLVED] MYSBootloader FOTA Update hangs on ProMini-3V-8MHz (reboot problem)

[rafael156]

@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?

[gohan]

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

[rafael156]

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?

[Soloam]

@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)

[gohan]

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

[rafael156]

@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!

[tekka]

@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)

[rafael156]

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()...

• 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"

@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?
