Add edge-impulse-sdk into platformio for esp32 failed

Help
#1

Hello, I have C++ micro speech project generated. I want to deploy it to esp32 with external microphone INMP441. I’m using platformio for my project.
Here is my platformio.ini file:

[env:nodemcu-32s]
platform = espressif32
board = nodemcu-32s
framework = arduino

lib_deps =
edge-impulse-sdk
model-parameters
tflite-model

monitor_speed = 115200
upload_port = COM[6]

And here is my project architect

|–include
|–lib
| |–edge-impulse-sdk
| |–model-parameters
| |–tflite-model
|-- src
|–platformio.ini

When build prject, I receive warning that edge-impulse-sdk cannot found:

I don’t know where is the problem, please help me. Thanks in advance

Hi @HuyYuh,

If you are using the Arduino framework in PlatformIO, could you download the Edge Impulse firmware as an Arduino library (.zip file) and include it that way? Here is an example project demonstrating how to include the .zip Arduino library in a PlatformIO project for the ESP32: https://github.com/edgeimpulse/esp32-platformio-edge-impulse-standalone-example.
