STM32WB about BLE

[Minkyu Kim]

Hello,

I made 2 project about client and server using stm32wb1mmc product.

 > server project is using "custom p2p server"

It works well but I want to improve usability.

1. How to reduce scan time for connect client to server?

  > I quote it from examples. use "CFG_TASK_START_SCAN_ID" when external pin interrupt is set.

    so when button is pushed, client start scan request. after 10s appx, client can be connected server.

    I want to reduce this time.

2. How to enter sleep(stop) mode cpu2?

As far as I know, cpu2 can't enter stop mode after cpu1 & cpu2 booted completely. If it is correct, is it no way to cpu2 enter sleep and wake up?

I attached 2 project files.

best regard.

HELLO @Minkyu Kim 

What can be done, is to terminate the scan procedure by issuing the command ACI_GAP_TERMINATE_GAP_PROC as soon as the p2p server is found (seeDeviceServerFound variable in app_ble.c).       

The CPU2 manage on its own the best low power mode to be applied and the application shall only take care of the CPU1 low power mode in the same way that you would do on any STM32 single core platform.

Best Reagrds.
