SUMMARY

The iPhone 4S utilizes Bluetooth Low Energy (BLE) technology, which theoretically allows for multiple simultaneous connections to BLE devices. However, in practice, the iPhone 4S can only maintain one active connection at a time, with additional paired devices entering a standby mode. This limitation is a result of the device's firmware and not a restriction of the BLE specification itself.

PREREQUISITES
  • Understanding of Bluetooth Low Energy (BLE) technology
  • Familiarity with iOS device capabilities
  • Knowledge of Bluetooth pairing processes
  • Awareness of firmware limitations in mobile devices
NEXT STEPS
  • Research the specifications of Bluetooth Low Energy (BLE) and its capabilities
  • Explore the firmware limitations of the iPhone 4S and other iOS devices
  • Learn about the differences between Bluetooth Classic and BLE
  • Investigate how to manage multiple Bluetooth connections on iOS devices
USEFUL FOR

iOS developers, Bluetooth technology enthusiasts, and anyone interested in the capabilities and limitations of Bluetooth connections on mobile devices.

iPhone 4S comes with the latest Bluetooth Low Energy Module. By BLE Spec, the BLE module can be paired to more than multiple slaves/nodes simultaneously. I would like to know if 4S can be paired with multiple BLE enabled devices simultaneously?

I am not sure if I have posted my query under right Topic. Would gladly appreciate answers

Only one at a time. All other "connections" will be placed in stand by mode.
 
But as per spec isn't Bluetooth Low Energy (BLE) is capable of getting paired with multiple BLE enabled devices simultaneously?
