its exactly as you guys say. taking a mega solves my issue and thats fine. i work with arduinos for many years now but its the first time i ran out of storage so i did not have this on the radar. i also learned much about arduinos with that issue. i guess thats a huge thanks for steering me into the right direction.

@mfalkvidd
i will definetly do that within the next days.

hey. i was having the same problems from time to time - i found out that its mostly wiring - therefor i am a great fan of easypcb and other boards that let one mount the radio directly.
and also mounting a fan on my gateway (rpi3b) helped a lot with that. other than that repeaternodes...

also install myscontroller - makes debugging way nicer and more efficient because you see in realtime whats going on... you might not have just one problem but more at the same time.

as soon as i burned a new bootloader it worked. watchdog does not like old bootloader and since mysensors is using that for rebooting it fixed my issue.

@tekka
EDITED ANSWER*: it worked!

• it did not work because of a typo... sorry for that....

@mfalkvidd said in mysbootloader with MY_SIGINING_SIMPLE_PASSWD:

@zen85 MySensors is open source. Anything is possible, if someone builds it :)

i am thinking about digging into this since this is the only thing missing i would love seeing. i really want the network secured with a password to be safe. i guess the main limitation is the size of the bootloader and therefor it has to be extremly clever... am i right?

or are there other options i am not thinking about to make my network a bit secure?
