Unable to update Bluetooth connection paramaters. QT BLE

[ZainMehdi]

I am trying to update connection parameters of my BLE connection. My device is in peripheral mode and I am trying to connect to an IOS device. I tried to call

void QLowEnergyController::requestConnectionUpdate(const QLowEnergyConnectionParameters &parameters)

I received connection updated signal but the paramaters are always the same and there is no update.
Here are the values I get
latency : 0
maxinterval : 60
mininterval : 60
