Hi,

If you suspect that shell is enabled, you can check it in your local configuration, ie my-build-folder/zephyr/.config file, and search for "CONFIG_SHELL" to see if it is y-selected.

Another option can be to delete the property:

/ {
...
	chosen {
		/delete-property/ zephyr,shell-uart;
		...
	};
};

Kind regards,

Håkon

Hi Håkon Alseth thanks for your quick reply.

[quote userid="2115" url="~/f/nordic-q-a/107362/atv2-app-hangs-in-uart-isr/464230"]By default, the at_host library will claim the uart0 interface. You can choose another UART instance for your module, or you can disable it via CONFIG_AT_HOST_LIBRARY=n to see if this improves the scenario.[/quote]

CONFIG_AT_HOST_LIBRARY=n is already disabled,

I checked it is in the dts "nrf9160dk_nrf9160_common.dtsi" file. it is defined zephyr,shell-uart = &uart0; I couldn't see where it is disabled. Can you please help me to understand?

Hi,

CONFIG_SHELL isn't set by default in asset tracker v2. Isn't it the at_host that is blocking you?

By default, the at_host library will claim the uart0 interface. You can choose another UART instance for your module, or you can disable it via CONFIG_AT_HOST_LIBRARY=n to see if this improves the scenario.

Kind regards,
