What I want to do is do UART communication (UART_1) between nRF52840 and nRF9160.
From the nRF52840 side, uart_poll_out is OK,
From the nRF9160 side, uart_poll_out examined because it was not.
Binding is performed on both:
uart_dev = device_get_binding("UART_1");
z_impl_device_get_binding the device name of the device is stopped with a matching for statement,
On the nRF52840 side UART_1 remains intact.
On the nRF9160 side, UART_0 possible.
On the nRF 52840 side, if it continues, it becomes RNG.
Continuing on the nRF9160 side I2C_2 operation.
Is prj.conf set up wrong?
