How to decrease the possibility of BLE disconnection when in connected?

SDKv14.2   SR3v1.2

If we want the RCU stay awake all the time when BLE is connected with a host, would it cause the possibility of random BLE disconnection?

Is this all about the connection event not be received by host in supervsion time-out? 

If it is, can we decrease the probability of disconnection by decreasing of connection interval? 

Thanks.

There is no reason why the peripheral should disconnect when in a connection, even if no data is sent. You may just send some battery level notification every 10 seconds, but it should not be necessary. A disconnect by supervisor timeout should only occur if they are out of range or one device is powered off after supervisor timeout period have elapsed.

Best regards,

Yes, I do send battery level notification every 10 secs. 

So it must be other reasons?
