Question/Issue:
Trying to read IMU data from ESP32-S3-EYE via edge-impulse-daemon failed with sample data timeout message
Context/Use case:
Have downloaded the firmware from Alex’s github at GitHub - figueiredoAF/edge_impulse_esp32s3eye_ingestion_sdk: Edge Impulse C/C++ ingestion sdk adapted to run on Espressif ESP32-S3-Eye and tried to use the IMU sensor (qma7981) onboard of ESP32-S3-EYE via edge impulse CLI.
Steps Taken:
- Go to GitHub - figueiredoAF/edge_impulse_esp32s3eye_ingestion_sdk: Edge Impulse C/C++ ingestion sdk adapted to run on Espressif ESP32-S3-Eye and git clone the project to my drive.
- Install ESP IDF4.4
- Made some minor changes including comment out all code in
.\LIS3HDTR_ESP_IDF\CMakeLists.txtto unselect LIS3HDTR, then include the following code in.\QMA7981\CMakeLists.txtto make sure QMA7891 is compiled and linked for the edge impulse firmware:
if(IDF_TARGET STREQUAL "esp32" OR IDF_TARGET STREQUAL "esp8266" OR IDF_TARGET STREQUAL "esp32s3")
set(COMPONENT_SRCS
qma7981.c
)
set(COMPONENT_REQUIRES bus)
set(COMPONENT_ADD_INCLUDEDIRS
.
../bus/include
)
register_component()
endif()
- Go to the root directory of the project and type in
idf.py fullcleanfollowed byidf.py build. No compile error encountered. - Connect ESP32-S3-EYE to my PC, learned it is COM68 in my PC, and type
idf.py -p COM68 flash - Open Serial Monitor in Arduino with the following messages which means the board is running.
13:43:21.759 -> Hello from Edge Impulse Device SDK.

- Close Serial Monitor, from ESP-IDF 4.4 PowerShell, go to the root directory of the project, and I typed in
edge-impulse-dameon, with the following messages:

- I was directed to my Edge Impulse Account of device “mictest”, acquire audio sample from the web interface. The following messages show up on CLI, which means built-in mic is working. Actually I tried camera too and it is working too.

Then I switched to IMU sensor and repeating the procedures to sample some data.
Expected Outcome:
I expected to read some IMU data and get it uploaded to EI automatically.
Actual Outcome:
