noun
The Bluetooth Core Specification (BCS) has been updated with Bluetooth 4.2, bringing new features and benefits to Bluetooth Smart.
How does Bluetooth work?
In version 4.2, the transmit power modes have been increased from +10dB to +20dB for BLE PLC Class 1. This means that many Bluetooth designs can be implemented without external power adapters, which can be cost-effective and save board space for end users.
In payment processing, card readers enable contactless payments via Bluetooth and/or Wi-Fi connectivity.
