Hi,

uart1 and i2c_1 use the same memory base address and can not be used simultaneously, see https://infocenter.nordicsemi.com/index.jsp?topic=%2Fps_nrf9160%2Fmemory.html&cp=2_0_0_3_1_1&anchor=topic for more info on what have the same ID.

[quote user="xinjiang"] tried I2C_3 and it worked.[/quote]

if this solved you problem then mark it as suggested answer.

Regards,
Jonathan

I tried I2C_3 and it worked. I have used uart0, uart2 and uart3, so I can only use I2C_1 now. This problem has bothered me for a long time.
