The parameters of Max, min and lcy will affect the power consumption in the equipment
connection state and transmit the delay of receiving data.
In addition, Max shall not be less than min, timeout must be greater than the effective connection
interval, that is, connection gap * (1+latency); If the device is a slave device and enable is set,
whether the parameters can be updated successfully depends on the master device. For example,
for IOS devices, apple has some parameter range limits. If the limit is exceeded, the update will be
rejected by IOS devices. Please refer to the apple document for details.
