I need to send a lot of bytes via BLE. I am able to view current consumption of CC2541 on oscilloscope. So i see how CC2541 transmit and receive packets each connection interval. And i noticed that when my connection isn`t encrypted CC2541 sends 3 or 4 packets per connection interval. Such situation provides sufficient level of throughput at 30ms connection interval condition. But i need encrypted connection. After enabling pairing and bonding i noticed that CC2541 sends 2 or rarely 3 packet per connection interval. It`s not enough to provide desirable level of throughput. I use BLE Bridge application on CC2541 and nRF connect on Nexus 5 smartphone. I have no idea which side makes such impact on throughput. And my question is - is it common for ble stack (CC2541) to reduce amount of packet per connection interval if encryption is enabled?
