@waspie why?

@nagelc I also use normal interrupts. No problems here. Up to 22uA while sleeping, that's fine by me. (3 AAA will last a long time)

@waspie you might want to look at one of my projects on openhardware. It has a sketch on it. It also uses the am612

A quick Google pointed me to https://github.com/AndruPol/nrf52832-recover/blob/master/README.md

I do have a STM32F103C8T6 laying around. But ATM no time to play with it.

Maybe that's the €3 solution for unlocking.

@smilvert do you have some more information? like some serial output?

I had some issues with statements that uses millis(), in about 1,5 up to 2 days (much shorter the normaly I suppose) it did its rollover back to 0. This messed some waiting times for me.

FYI:

Yesterday I tried to use the MY_ENCRYPTION_SIMPLE_PASSWD and SIGNING (so not MY_SECURITY, everything separate), the gateway also crashes after a couple of hours.

So reverted all my sketches and now only have MY_ENCRYPTION_SIMPLE_PASSWD on all my nodes. Since that time I've been receiving everything and had no crashes.

I posted a Log of the gateway from boot (around 2 hours ago) to last crash.

https://github.com/Omemanti/Paste/blob/master/Gateway_log_01-01-2019_security.txt

everything seems normal (to me) except de crash in the end.

@anticimex said in Nrf52 gateway crashes:

@omemanti it is not clear from your message what actually happened. Did something stop working?

like posted a month ago; it "sometimes" stops working at the following line:

0;255;3;0;9;759816 TSF:MSG:READ,215-215-0,s=2,c=3,t=16,pt=0,l=0,sg=1:
0;255;3;0;9;759818 NRF5:SND:TO=215,LEN=32,PID=2,NOACK=0

All nodes in the network are sending in data every 5 to 10 minutes (depending on the node) it all runs smoothly up until the line like above comes around. So all nodes send data and are using the same password etc.

All went oke when I changed to only encryption, when I went back to security it starts breaking again.
Average time form rebooting the gateway up until crashing averages from 30 minutes up until 15 hours. (yesterday I rebooted the gateway at 8:00 and it stopped working at 23:30)

A month ago, I changed my sketch.

I replaced "MY_SECURITY_SIMPLE_PASSWD" to "MY_ENCRYPTION_SIMPLE_PASSWD" because this was most important to me. Nothing bad happened, I received everything in perfect order.

for the sake of testing, I switched back to "MY_SECURITY_SIMPLE_PASSWD" a couple of days ago, Guess what is happening since that time.

So there are to options to consider, or the implementation of MY_SECURITY_SIMPLE_PASSWD has a bug, or the Simple Signing is messing with my gateway.

Can you tell something about the range of this node?

And do you see a chance to post the schematic?
