How exactly can we use XIAO BLE Sense to collect audio data from PDM microphone via Python?

You got me with this :D
Maybe try it with circuitpython first?

Hi: When connect the XIAO 52840 sense microphone with “edge-impulse-data-forwarder” and try to use data acquisition i get the error: Invalid data collected from device. Also on Collect data section i see Sensor: Sensor with 1 axes Frequency: 2646Hz. On the logs appear: Failed to sample data Error: Invalid data collected from device. Can you help me?

Hi! Sometimes the PDM is not working properly. The voice collection using microphone on the computer is better than using digital microphone on Seeed Studio XIAO nrf52840 and brings more accuracy.
