Hi, 
 It is not possible only to disable Rx part after connection established between master and salve.
Once connection is established between central and peripheral device,
each devices need to syncronize per connection interval(7.5ms~4s) in order to keep connection,
which needs to send and recieve empty packets even if nothing any data you want to send and receive. 
 If you want to reduce some degree of power consumption while sending and receiveing,
you may have an option to enable internal DCDC converter. 
 Thanks.
