Hi ST Experts,

We have a BLE project based on the STM32L476 and HM11 BLE and we are looking to minimize the component count and shrink the board size. We want to replace the STM32L476 with a BLE and MCU single chip solution and we are considering the STM32WB55CGU6, kindly advice the most suitable MCU for a BLE.

We also need a single chip BMS solution with integrated charge controller, protection circuits (Over temperature, over charge/discharge protection etc), Wireless charging (is nice to have), Integrated battery gauge with I2C interface (to read out battery State of Charge and battery Health).

We would love to schedule a meeting to discuss further our requirements.

Looking forward to your response.

Regards,

Paul.

Sounds like you want an FAE?

to contact ST direct, see: https://ols.st.com/s/

Or maybe try your local distributor: https://www.st.com/content/st_com/en/contact-us.html

Thanks for your response.

So for the battery, we are looking at a 3.7V Li-Po/L-ion battery. The capacity can be up to 5000mah.

And yes we'll like to talk to a field application engineer.

Start with the people you're buying from currently..

Find your local sales office, or rep.

I don't work for ST, and am employed in entirely different capacity/field. Perhaps you can find some consultants in the battery/charging domains, or some specific contacts within ST in those domains on places like Linked In, or Fiver.

Distributors used to fill some of those roles, and holding/managing stock/inventory, but sadly most of that has evaporated as a value-adder. I also see fewer reps than I did a decade ago. Generally $B companies expect you to move volume, and have your own rosta/depth of engineering staff.

Your Profile/Posts also provide no location or market info, nor any indication that your company, yourself or your buyer does any direct business with ST. If you work with Distributors, push in there.
