KB: Supported Advertising and Connection Intervals in the RSL10 Bluetooth Low Energy Stack


[RSL10 - Knowledge Base]


Question

The Bluetooth Low Energy stack included within the RSL10’s Libraries supports a variable advertising and connection interval that can be changed at the application level.

What is the supported range of values that these parameters can operate at, and what is the resolution of the steps that can be achieved?


Recommendation

The chart below outlines the advertising and connection intervals supported by the RSL10 (and specified in the BLE Spec) along with the corresponding step resolution.

BLE Operations Min Interval Max Interval Step Size
Connectable Advertising Interval 20ms 10.24s 0.625ms
Non-Connectable Advertising Interval 100ms 10.24s 0.625ms
Connection Interval 7.5ms 4s 1.25ms
