Silicon Labs recently announced two hardware modules based on its BG22 Secure Bluetooth 5.2 SoC: 6x6mm BGM220S system bundled (SiP) and slightly optimized for wireless performance with a better link budget. BGM220P introduced, large PCB variant, wider range.
Both modules can be integrated into products with a battery life of up to 10 years using a single coin cell battery. All variants of BGM220S/P can support Bluetooth directional discovery, and some components can also support Bluetooth mesh low power protocol.

Industrial use of ESP32-based solutions
One of industrial IoT devices, supporting Espressif’s ESP32 and Bluetooth technology is eModGATE from TECHBASE. Economical, ESP32-based solution can serve as an end-point in any installation or works well as a gateway, gathering data from scattered sensor mesh across the installation. For more information check Industrial IoT Shop with all the configuration options for eModGATE.
