STM32WB55 FCC Certification

[Viswajith]

Hi everyone,

I’m working on a product using the STM32WB55 with BLE and Zigbee static concurrency, and it’s now moving into the FCC certification stage.

I’ve come across the Phy_802_15_4_Cli application along with the wireless coprocessor firmware (stm32wb5x_Phy_802_15_4_fw.bin), and I want to confirm whether it covers the requirements for test mode.

My requirements are:

1. Continuous transmission (both unmodulated and modulated) on a single channel

2. Channel selection (e.g., 2402, 2440, 2480 MHz for low, mid, high)

3. Maximum duty cycle (100%) transmission

4. Fixed transmit power at the maximum rated level

5. Option to enable hopping/modulation patterns (for BLE)

From what I’ve seen, the Phy_802_15_4_Cli application seems to provide almost everything except hopping. Would this application be sufficient for FCC test cases?

Also, has anyone here used other applications or tools for FCC or similar certification testing?

Thank You.

Hello,

I'd suggest taking a look at the CubeMonitor-RF tool (a PC tool) which is indeed meant to be used in certification. You can find more info and download here STM32CubeMonRF | Software - STMicroelectronics.

It can be used with Phy_802_15_4_Cli application + stm32wb5x_Phy_802_15_4_fw stack, or with BLE_TransparentMode application + stm32wb5x_BLE_Stack_full_extended_fw stack.
