This blog is to show the BLE throughput on difference users scenarios. I plan to show the maximum throughput on the real world, particular showing how fast the BLE communication with IOS devices.
I would use 2 x nRF52840 DK for the central and peripheral bi direction communication and print out the live throughput. After that, I would show that how to achieve the maximum of Bluetooth throughput on IOS.
Follow up the blog https://jimmywongiot.com/2019/12/15/how-to-set-the-bandwidth-on-ble-link-connection/, Nordic Softdevice can achieve up to 800Kbps on BLE 4.2 or 1.3Mbps on BLE 5.0.
Requirement & Procedures
- nRF52840 DK x 2 (BLE Peripheral / Central)
- Bluetooth 5.0 (2Mbps)
- Sending 1MB data from either side
Data (1MB) is sending from peripheral to central
Data (1MB) is sending from Central to Peripheral
Scenario 2 (Connect with IOS)
nRF52840 DK (BLE Peripheral) + IOS (IPhone Max XS) [IOS 13.3.1]
By following Apple Bluetooth Development Guideline, https://developer.apple.com/accessories/Accessory-Design-Guidelines.pdf, I setup the demo to send data from device to IOS as below.
The maximum of BLE throughput with IOS is around 3xx kbps (1Mbps) and 6xx kbps (2Mbps)
