Implementation of edge impulse model my nrf5sdk code

When I want to implement my edge impulse model to my nrf5sdk code using vs code I found this errors,

have you any idea about how to fix this?

Hello, 

The Edge Impulse is only supported in the nRF Connect SDK. 

Kind regards,
Øyvind

[gizgiz]

but there is some people who used nrf5sdk with edge impulse

and there is an example:Including my deployed C++ Library in my Segger Embedded Studio Project - Edge Impulse

[Øyvind]

Yes, I understand, however, this is Edge Impulse's own project. Please refer to the Edge Impulse Forum for questions on nRF5 SDK integration. There is no official support for Edge Impulse in the nRF5 SDK, you will need to port this your self. 

A quick search in the EI forum gave me this: https://forum.edgeimpulse.com/t/deploy-edge-impulse-to-nrf52832-via-nrf5-sdk/3024/2

Hope this helps

Kind regards,

Øyvind

The output clearly states undefined reference(s) from the Edge Impulse SDK. As this is not a part of the nRF5 SDK you will need to contact Edge Impulse forum for support.
