Take a look at ncs\zephyr\tests\drivers\uart\uart_basic_api\src\test_uart_poll.c

I'm going to give up on callbacks and make it a polling process.

Is there a sample that is polling?

Thank you for answering.

I changed it to UART1 and went running, but the phenomenon did not change.

prj_thingy91_nrf9160ns.conf changed as follows:

CONFIG_UART_ASYNC_API=y
CONFIG_NRFX_UARTE=y
CONFIG_NRFX_UARTE1=y
CONFIG_NRFX_SPIM=n
CONFIG_NRFX_SPIS=n
CONFIG_NRFX_TWIS=n
CONFIG_NRFX_TWIM=n

thingy91_nrf9160_common.dts has not changed.

It is set as follows:

chosen {
zephyr,console = &uart0;
zephyr,shell-uart = &uart0;
zephyr,uart-mcumgr = &uart0;
};

&uart0 {
compatible = "nordic,nrf-uarte";
current-speed = <115200>;
status = "okay";
tx-pin = <18>;
rx-pin = <19>;
rts-pin = <20>;
cts-pin = <21>;
};

&uart1 {
current-speed = <1000000>;
status = "okay";
tx-pin = <22>;
rx-pin = <23>;
rts-pin = <24>;
cts-pin = <25>;
};

Are you able to use another UART instance than 0? Instance 0 is used for logging, and I assume it causes some issue when you change the callback handler. Remember to configure the UART instance in an overlay file, if not already configured in the dts board files (nrf/boards/arm/thingy91_nrf9160/thingy91_nrf9160_common.dts). Also, make sure to disable the SPIM/SPIS/TWIS/TWIM peripherals of the same instance (TWI=I2C).

Best regards,

Simon
