How to dynamically change the connection interval

[Kc Owen]

Why do I use this function bt_conn_le_param_update( ), only after the power on the first time to work, then do not work

I used NCS 2.6.0

Hi,

There should not be any limitations on how often you can call bt_conn_le_param_update(), and updating the connection parameters several times during a connection is common. In what way does it not work?

[Kc Owen]

After the Bluetooth connection is complete, bt_conn_le_param_update() is executed in the connected callback function. However, bt_conn_le_param_update() is executed in the code for synchronizing historical data but does not work.

This is a change from the CGM example

Is there an example of updating connection parameters multiple times during a connection？
