The connection interval is a parameter for the connection state. If two devices are not connected, this parameter will not affect the power consumption in this state.

At present, the reason why e-bike/e-scooter sharing is so hot is that the customer experience is very good. In a busy city, spending a dollar to ride a bicycle/bike can save time and is very pleasant. A few years ago, we couldn’t even think of unlocking a e-bicycle/e-scooter with a mobile phone that turned on Bluetooth.

Bluetooth technology's new generation core specification version "Bluetooth 5" (Bluetooth 5), its main updates include longer transmission distance, faster transmission speed, larger broadcast data transmission volume, and interoperability with other wireless technologies and Improve coexistence.

Everyone should have a simple understanding of the Bluetooth protocol stack, but there must be a feeling of "seeming to understand, not to say, to rest".
