Dear STMicroelectronics Team,
I am writing to strongly condemn the way power consumption values are presented in the STM32WB55 datasheet.
When I choose a wireless SoC, I do so because of its wireless capabilities. If I only needed a microcontroller, I would simply buy an MCU from your STM32 families. The reason I selected WB55 was specifically for its BLE functionality. Therefore, the datasheet must provide power consumption values with BLE active, not just MCU Stop mode currents with BLE disabled.
Presenting only the MCU’s low‑power figures while omitting the real BLE consumption is misleading and deceptive. It creates false expectations for developers and leads to serious disappointment in real‑world applications. This practice can only be described as fraudulent.
I strongly denounce this approach. Wireless SoCs must be documented transparently, with accurate BLE advertising and connection current profiles. Competing vendors such as Nordic and Telink provide this clarity, and ST should do the same if you want developers to trust your wireless portfolio.
I urge you to revise your documentation and stop presenting wireless SoCs as if they were just MCUs. Anything less is unacceptable.
