Hi,

[quote user="John12"]I'm using nRF52833, nRF16 SDK[/quote]

We did some fixes when it comes to libuarte unint in SDK 17. Please try to backport these libuarte files from nRF5-SDK 17.1.0 , and see if it solves the issue:

nrf_libuarte_async.c
nrf_libuarte_async.h
nrf_libuarte_drv.c
nrf_libuarte_drv.h

I tried to wait for the event TX_DONE before uninit but after 1/2 days hang my device, I get an error that nRF Uarte can't receive anything from SIM or GPS
When I check third party SIM and GPS still working. It's to hard to get this error because when I hang this device for 1/2 day or sometimes 1 day to get this error

[quote user="John12"]Thank for your suggestion. I'll try.[/quote]

Ok, let me know how it goes.

Looking at your code-snippet, there was no delay between sending and nrf_libuarte_async_uninit()

Hi Sigurd,
I'm using nRF52833, nRF16 SDK

[quote userid="15146" url="~/f/nordic-q-a/90550/uarte-crash-when-init-and-uninit-continoulsy/379646"]Could you try waiting for the event NRF_LIBUARTE_ASYNC_EVT_TX_DONE , before calling nrf_libuarte_async_uninit()?[/quote]

Thank for your suggestion. I'll try.
But in my program each uninit / init uarte I added nrf_delay_ms (2000). I think wtih small amount of data I transfer. 2000ms is enough too uinit / init uarte

Hi,

What SDK version are you using?

Could you try waiting for the event NRF_LIBUARTE_ASYNC_EVT_TX_DONE , before calling nrf_libuarte_async_uninit()?
