Does the serial function operate with a soft device. Whenever i have an include statement for serial.h in a file with a softdevice I get a No such file or directory compilation error. In the main file can open declaration etc. Can also specifically add an include path without changing compilation error. If i just compile the serial example then all is ok.
Using a nRF52840 I need two UARTs services if required to use UARTE instead of serial how do you specifically configure and use the device?
Could you take a screenshot of the problem when you try to compile ? Make sure you include all the needed .c file and path to .h file.
Make sure you updated sdk_config.h to enable UART (set NRFX_UARTE_ENABLED = 1) and NRF_SERIAL_ENABLED = 1.
Serial library uses drv_uart as the backend, you can have multiple instance. There are 2 instance of UARTE on the NRF52840.
I have attached a screenshot of the issue. I have compiled and successfully run the serial example in SDK revision 15 using the updated files in NRF52840 UART1 not working in SDK 14 and have ensured that the configuration file in the buttonless DFU config for UARTE/UART is equivalent to the

Have you made sure you have the include path correctly ? Could you take a screenshot of the User Include Directories that show the /components/libraries/serial included in your project (inside Option -> Select Common configuration)
I have edited the makefile to include the required paths. Functions can now be included.
