Hello,
I'm using WBA55CG Board and i have tried to flash this example STM32WBA Bluetooth® LE – Serial communication - stm32mcu to the STM32. The flashing step is completed, i could connect the board through ST BLE Toolbox on iOS. However there is no services like in the example, for example Send button/Real time. Also i have connected the board with TeraTerm to see USART messages but there were no messages from the board. How should i debug to have a proper function?

Hello @Henry_BLE 

To be able to connect the BLE_SerialCom_Peripheral to the ST BLE Toolbox, you need to have the COC option available on your application. This option is supported by the android version only.

Best Regards.
