General description

The conceptual drawing in

Figure 1 shows the BLE stack partitioning; meanwhile a

simplified application schematic is shown in

Figure 2.

Figure 1. BLE stack

Figure 2. Simplified application diagram

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.
