RE: SLM: connect to external MCU using UART2

Here is what I get after changing config to UART2

Hi Oyvind, I'm having trouble with the same issue. But after I set the UART2 for the first time, the menuconfig never loads again. Can you walk me through how to manually change these parameters?

thank you. Worked fine!

Please try setting the UART_2_NRF_HW_ASYNC_TIME=2 manually in menuconfig in SES. This worked for me. This is the only work around at the moment.

The issue is UART_2_NRF_HW_ASYNC_TIME which is set at the same time as SLM_CONNECT_UART_2, is not configured with a value. I am currently working on a work-around.

exactly the same, yes

Ok, I have been able to reproduce this issue.

Are you getting the same output in SES? (Under the configuration window)?

Now I installed a fresh NCS v1.4.2 via toolchain manger

Built SLM as is in SES -> ok

Changed both configuration options from within SES -> tried building -> error as shown below

RE: SLM: connect to external MCU using UART2

I have not changed anything but the two setting in prj.conf

I'm using the toolchain manager, and the same error appears using bash.

I am not able to reproduce this error.

Are you using NCS via the Toolchain Manager? I've tested using both SES and Bash in NCS 1.4.0 in Toolchain Manager. Have you added anything / configured anything else in your NCS?

I did set both configuration options in SES. Then the configuration failed with the before mentioned error. However, when changing the options in prj.conf instead, I got the following compilation error (same error with west and SES):

RE: SLM: connect to external MCU using UART2

Øyvind — Thu, 04 Feb 2021 12:41:33 GMT

Hi,

In prj.conf there are two lines for UART_2, did you configure both?

"To connect with an external MCU, you must set the configuration options CONFIG_SLM_GPIO_WAKEUP and CONFIG_SLM_CONNECT_UART_2 in the serial LTE modem application configuration."

Can you provide the output log when building?

Thanks
