Hey dear nordic support team
hey all nordic users,
I would like to report an error that is happening with devices that have very low sleep time intervals ( 3 min or 5 min). After a while those devices are crashing with an error shown in screen shot below (UART Logs). I also attached the UART logs in a file, the devices were working fine an after a while they crash ( all cases are with devices with low sleep time)
Its also important to mention that this never happened before. Now it is happening again and again: Device crash, we reset it, it works again and after a while it crashes. Its not also just one device, its happening with a lot of devices with low sleep time intervals
We are working currently on the firmware to make the device recover alone after that . We would love to get your insights and the experts from Nordic on why this is happening, since this is a modem crash coming from Nordic? what is this PC:0x9a776 reason? what to do to avoid this error or fix it?
attached you find also the UART logs
- LTE-M
- Modem firmware version 1.3.5
- Connection was successful before, no other issues
- Data was transferred
- we always Reboot the device when waking up from sleep mode
I: Modem library successfully shut down
I: new sleep time in seconds : 130 (-49 Elapsed Time in seconds)
I: Alarm set for 130 seconds.
I: Going to deep sleep
