      On the CC13x4 / CC26x4 Bluetooth LE examples connection timeouts are observed during very aggressive data streaming use-cases when repeatedly changing the PHY and the MTU size.

      SDK: 7.10

      Tests were executed on Data Stream application, which utilizes GATT Notifications.

      Test Sequence:
      1. Tester (CC2652R1) initiates connection, pair and bond
      2. Register for Data Stream Notifications
      3. Loop through:
      a. Discover Data Stream Service By UUID
      b. Discover Data Stream Profile Characteristics
      c. Stream Data (GATT Write)
      d. Receive Notifications (fragmented or not)
      e. Once in 5 minutes: change PHY, change MTU
