Request for Suggestions: Low-Power Bluetooth Device Design

Kavinraj

Dear Team,

I am currently working on designing a low-power Bluetooth device and we need a suggestion as to choose an ultra-low power consumption and distance to meet BLE MCU

In particular, I am looking for advice on:

  • Selecting the best STMicroelectronics microcontrollers or SoCs for low-power Bluetooth applications.
  • Implementing power management techniques to achieve optimal energy efficiency.
  • Any available reference designs, application notes, or resources that could be beneficial to my project.
  • The objective of the project is to meet the Accurate distance between BLE devices using RSSI

 

Note:

Already we have used the STM32WB5MMG series MCU for BLE, but it does not meet the distance and expects low power,

 

Your suggestions would be incredibly valuable, and I look forward to your expert guidance.

Thank you for your support.

Hello @Kavinraj 

I suggest you try your tests using the STM32WBA MCUs and the STM32WB1MMC. I think they should give you acceptable solutions for your project. 

Best Regards.

You cannot accurately determine distance using just RSSI.

At best, you'll get a broad "near/far" indication.
