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

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?

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?
Is there no requirement for the interval between the first call to bt_conn_le_param_update() and the second call?
You cannot initiate a new control procedure whiel another you initiated is actice. Perhaps that is what happened here? If you do, bt_conn_le_param_update() will return an error. I expect this is what happened here.
