I have a ST B-L475E-IOT01A connected to edge impulse api, I am getting following error when trying to sample data and upload:
[SER] Configured upload settings
[SER] Sampling started
[SER] Sampling done
[SER] Uploading started
[WS ] Failed to sample data Timeout when waiting for > (timeout: 80000) AT+SAMPLESTART=Built-in accelerometer
I have used the latest firmware for this board from edge impulse site and connected through serial port. Please advise what is causing the sampling and upload to fail.
Thank You
