https://devzone.nordicsemi.com/f/nordic-q-a/95057/low-power-uart-timeout-causes-micro-to-hang-upHi, we are using the LPUART in async mode to communicate between an nRF52840 and an nRF9160. Everything works well except when a timeout occurs. I noticed this when the other micro is being bootloaded and the nRF52 tries to communicate with it.

He needs to do some maintenance work on the LPUART driver, and will have a look at this issue as well.&nbsp;It will be a bit of a wait until he has time to look into it though, I will ask if he can provide a schedule for a fix.&nbsp;</p> <p>In the mean time would it be an acceptable workaround to enable the watchdog on the nRF52 side?&nbsp;<br />Then the MCU would reset rather than just locking up, which should allow it to recover.&nbsp;</p> <p>Best regards<br />Torbjørn</p><div style="clear:both;"></div>
