nrf9160DK Serial LTE Modem COM port wiring

[austinaoe]

Hi there, I'm routing the nrf9160 to a STM32 and I need to know the pinout for COM port used.

On my PC, I know COM11 is the one that is used for AT Commands

But, I don't know how to map it to the uarts...please let me know!

Hello,

what are you trying to do? Do you want to use a different UART instance than the default one for SLM?

Hi!  What i want to do is hook up the default com port used for the Serial LTE Modem application to my microcontroller.  On my PC that is COM11 but I do not know which UART that maps to.  Can you tell me the UART used for AT commands in the Serial LTE Modem application?

Is it uart0 as shown below?

The default uart instance is uart0, as evident in the documentation.
