UARTE non-blocking example usage

[kenlove]

Hi,

I encountered some problems when using UARTE.

In terms of hardware, I have connected the 52840DK LOOPBACK_PIN_1A and LOOPBACK_PIN_1B.

Software code is the original example.

What do I need to do to complete non-blocking uarte testing?

Hi,

The issue is coming because the driver is getting uninitialized in the handler.

Commenting out this line in the handler will resolve this issue:

nrfx_uarte_uninit(p_inst);

It should not have been here, and if you want to uninit then it could be done in the main after successful transmission and reception.
