Python programme for a vibration signal from Raspberry Pi 4 via bluetooth connection

[Tria91]

Hi,
please, I need some help to make a vibration signal, if possible with adjustable vibration-length, out from a Python programme from a Raspberry Pi 4 via bluetooth connection.

Best regards,
Gerald

That's a bit of an open ended question. Which OS are you using on the PineTime? One of them might have a mode for handling raw accelerometer data for easier development of the step counting or other activity tracking. If they don't have anything to suit your needs you'll have to write something yourself to collect the accelerometer data and send it over BLE to the Pi.
