UART between NRF52840 DK and NRF9160 DK

[RobertT]

Hello!

 I have a NRF52840 DK and a NRF9160 DK . The NRF52 will send AT commands through UART to the NRF91 modem. Tried to use the code from https://github.com/NordicPlayground/nRF52-clients-for-serial-LTE-modem for the NRF52 to send the AT commands. Did the set-up for the NRF9160 DK. Dowloaded the nRF5_SDK_16.0.0 and copied the folders there but I got build errors that it can not see many of the header files and also errors for different functions. I used SEGGER, opened the " nRF5_SDK_16.0.0\examples\peripheral\bsp " and replaced the .h and .c files from the folder " slm_client " into the " bsp " example. Question, general one, would be : how can I get that example from github to build correctly on my NRF52840 DK? 

Thank you!

Manage to build it . Used the Makefile from armgcc. Thank you ! This ticket can be closed.

Nice. Exactly at the same time as I posted an answer telling you to use this approach
