Recommend a BLE SoC with Eddystone support ?

Split from STM32WB05KNV6TR missing in STM32CubeIDE 2.0.0 Target Selector - this is a new question

---

Hi Ghofrane,

Thank you for the explanation. Since the WB05xN acts as a network coprocessor, it doesn't fit my current design goals as I want to avoid using an external Host MCU to keep the BOM cost and PCB footprint at a minimum.

I am looking for a standalone (single-chip) STM32 wireless solution. My requirements are:

1. Standalone Operation: The application and BLE stack must run on the same chip.

2. Eddystone Support: It must be capable of broadcasting in Eddystone format.

3. FOTA (Firmware Over-the-Air): The chip must support wireless firmware updates.

4. Cost-Effective: This is a price-sensitive project, so I am looking for the most budget-friendly standalone option in the STM32WB family.

Could you please suggest the most suitable part number for this use case? Would the STM32WB15 or the new STM32WB09 be the right direction for a low-cost, standalone beacon application?

Hello @burak_Guzeller ,

Using "STM32 Sidekick", I think STM32WB09xE is your best direction and most suitable for your requirements (standalone BLE operation, Eddystone support, FOTA, and cost-effectiveness).

Here is the summary result from "STM32 Sidekick":

• STM32WB09: suitable for standalone BLE beacon and FOTA applications, with moderate memory and peripheral options, and certified BLE 5.4 stack. It is highlighted as cost-effective and optimized for battery lifetime, making it a strong candidate for energy- and cost-sensitive applications. Offers more memory, advanced security, and is specifically optimized for ultra-low power and cost-sensitive applications. It is the recommended choice for standalone Eddystone beacon and FOTA use cases in price-sensitive projects.

• STM32WB15: Positioned as an entry-level solution for simple BLE applications, available on the NUCLEO-WB15CC development board, with slightly less flash but more RAM than WB05xN. It supports BLE 5.2 and is suitable for fast prototyping and development..
