In SDK 7.10, the feature has been tested configuring CC2340R5 as a peripheral and establishing 8 secure connections (using 8 CC2642R devices configured as central devices). The tests show:

• The CC2340R5 is able to establish and maintain the eight connections
• The CC2340R5 can maintain the eight connections on all the PHYs (1M, 2M,
  Coded S2 and S8)
• The CC2340R5 supports GATT operations (read and write) for the eight connections
• The CC2340R5 can pair and bond with the eight central devices
• No failures for 12 hours with connection interval of 800 ms, and for 6 hours with connection interval of 30 ms.
