SO,how to set BLE connection interval?
when the devices are connected,i want to save more power,so i want to increase the conncetion interval ,but i can't find how to redefine this param.
adv and scan interval is easily to set,i can't find the way to set connnection interval
i notice that IRQ has this event:
elif event == _IRQ_CONNECTION_UPDATE:
conn_handle, conn_interval, conn_latency, supervision_timeout, status = data
how to update connection,to change conn_interval, conn_latency, supervision_timeout

Q Qwen · high

The query asks how to set the BLE connection interval in MicroPython to reduce power consumption. The candidate PR (15494) modifies a test file to reduce the connection interval for performance testing purposes. While both items deal with BLE connection intervals, the PR is a test modification that uses the connection interval parameter rather than implementing the feature requested in the issue. The PR does not provide a public API or documentation for users to configure connection intervals, which is what the issue is asking for. The PR is related to the same component (extmod/bluetooth) and concept (connection interval) but does not resolve the user's question about how to configure this parameter.

Suggested action

Keep the issue open. The PR demonstrates that connection intervals can be set (via gap_connect parameters), but does not provide the user-facing API or documentation the issue requests. Consider adding documentation or implementing a public API for connection interval configuration.
