Use SPI instead of UART for AT commands communicaion

Technical Discussion

Hi,
The SDK has a switch to choose communication channel for AT commands (UART or SPI).
As default, the UART is chosen

#define CONFIG_EXAMPLE_UART_ATCMD	1
#define CONFIG_EXAMPLE_SPI_ATCMD 0

When trying to switch to SPI, by setting:

#define CONFIG_EXAMPLE_SPI_ATCMD 1
#define CONFIG_EXAMPLE_UART_ATCMD	0

…I’m getting an compilation error because few functions are no implemented.
The first one is: spi_at_send_string()
Where can I find implementation for those missing functions?

Thanks in advance

It looks like the example code is not available on the latest GitHub SDK. You can find the old code here, and you might need to modify the makefiles to ensure that they are compiled.
