The STM32L4 does not implement an embedded BLE capability as on the STM32WB and STM32WBA. But you can use the BLE capability after adding an external module. On the B-L475E-IOT01A IOT board, an external BLE module is integrated. So, you can use it for communication. If you are using an STM32L4 Board without such Module. You have to add one of the external Module.

So, the STM32L4 MCU does not integrate any ble capability. If you are meaning the ble module on the B-L475E-IOT01A, Then you can start from the following applications.and try to adapt this implementation to support Zephir.
