Hello support

I have modified the cli examples and run into "undefined reference to `nrf_cli_uart_transport_api'" linker error. 

The error message is

The terminal process "zsh '-c', 'make'" terminated with exit code: 2.

I am using visual studio code with GCC compiler.

Can you help?  Much appreciated.

Hi there,

I did more testing with the Nordic's recommended IDE (Segger Embedded Studio) and SDK nRF5_SDK_17.0.2_d674dde.  I found similar issue with the " `nrf_cli_uart_transport_api'".

Here is how to reproduce this issue.

1. UsenRF5_SDK_17.0.2_d674dde and Segger Embedded Studio v5.6
2. Open cli examples
    a. sdk_root\examples\peripheral\cli  or
    b. sdk_root\examples\peripheral\cliuarte
3. Build the solution. 

The error message is copied below

Compiling ‘nrf_log_frontend.c’

nrf_log_frontend.c
unknown type name 'nrf_cli_transport_api_t'
unknown type name 'nrf_cli_transport_handler_t'
unknown type name 'nrf_cli_transport_t'

Thanks

I was able to resolved this issue.  The reason is there is an inadvertent edit in my local copy of the NRF5 SDK that is creating this issue.  After deleting and then re-download the SDK, the examples compiles correctly.
