Dear Cypress.

I have some question of Cypress BLE.

How fast role Switching possible?

(Central <--> Peripheral)

How fast Bt classic Audio / Video Maximum transfer support speed?  

And I to be curious PSoc 4 / 6 Bluetooth through-put, Could you provide data?

Best Reard.

BRK.

Hello,

Could you please elaborate more on what the switching role delay time you are referring ?
For changing roles between a GAP Central and Peripheral, you can refer to the Day012_Central_Peripheral example project from the GitHub. In this project, the BLE Pioneer Kit starts by acting as a GAP Central that can scan and connect to nearby advertising devices. It can then change its role to a GAP Peripheral to connect with other Central devices. The changing of the GAP roles is done via commands sent over a UART interface. This project is based on PSoC4 BLE Device.

For Throughput measurement on PSoC 6 BLE device(BLE 5.0), you can refer to PSoC 6 MCU: BLE Throughput Measurement (FreeRTOS) CE from MTB. This code example demonstrates BLE throughput measurement (using GATT layer notifications and GATT write command) using PSoC 6 BLE MCU.

For PSoC4 BLE Devices, for BLE 4.1 devices, you can get a theoretical throughput of 298 kbps. In Bluetooth 4.2, the payload size is 251 bytes (2008 bits) and the total time is 2500 µs that gives the theoretical throughput of 784 kbps. Please refer to AN99209 PSoC4 BLE and PRoC BLE: Bluetooth LE 4.2 Features datasheet for more information on throughput calculation.

PSoC 6 BLE device does not support classic BT.

Thanks,
