I would like to know if it is possible to collect data on edge impulse through classic Bluetooth or BLE with a nano BLE 33 sense.
Thanks for answers
It is physically possible to do data collection via Bluetooth/BLE, but it is not supported by Edge Impulse. As a result, you will need to write your own firmware and applications to collect that data and either save them (e.g. to CSV files) or use the Edge Impulse ingestion API to upload the samples to your project on Edge Impulse.
