connection btw modem simcom7000 and nrf52840-dk

[rdmeneze]

HI!
I'm basically new with zephyr and etc. 

I'm developing a project with a nrf52840-dk board and a simcom7000 modem (assembked in a arduino expansion board) and basically I don't know how to configure the devicetree. The modem is very similar to simcom7080 and I think that should be possible to use the same driver to do some tests. 

can someone give me some directions? 

thanks in advance.

Hi

If you're new to the nRF Connect SDK and Zephyr RTOS I'd strongly recommend checking out the DevAcademy, where we have multiple free courses explaining the fundamentals of the nRF Connect SDK and how to get started developing. How to set up the devicetree is also its own topic here. https://academy.nordicsemi.com/ 

What serial communication does the simcom board support? I'd recommend checking out SPI if that's an option for you. As it is a simple and fast method of serial communication.

Best regards,

Simon

I did these courses. 
Well, the simcom board have a serial communication and a PWRKEY signal. 
The serial communication is connectes to the D1 and D0 arduino signals and the PWRKEY is connected to the D12.

I'm trying to use the Device tree editor and I don't know where I can add the modem...
