The protocol stack running in the host is released separately in the form of static library for
the STM32L. BLE qualified profiles are available separately.
The STBLC01 radio has been designed specifically for low power applications. The TX
output power can be controlled by the BLE host from -18 dBm to +3 dBm in order to
optimize the current consumption for a wide set of applications.
