Objective: This blog provides information about Bluetooth RF power class in Cypress Bluetooth devices and related certification queries.
WICED version: WICED SDK 6.2.1 or 6.4
Supported WICED device: CYW920706WCDEVAL, CYW20706 based modules
Details: Bluetooth devices may have different RF power classes depending on the Tx power and operating range of device. Following table shows the details about the classification:
Maximum Tx power
For CYW20706 devices, by default, firmware supports class 1 with maximum Tx power +12 dBm for BR/EDR applications and +9dBm for BLE applications. There are two ways to change the Tx power, i.e. RF power class-
