What would you suggest instead?

  Nordic Semi, or maybe ST Micro. I've got an STM32WB on my bench at the moment with sensitive coulomb counting and it looks very promising but without all those radios. Of course with all those radios (ie, if you need LoRa on a watch... which is a design decision I'm also skeptical of) then Nordic has a good track record.

    Different use case (environmental data recorder) but our current product uses an STM that turns on an ESP32 (not trusting that sleep mode) when it needs radio, to run on 2 AAs forever.

      Do you have any info you can share on this recorder? Sounds really interesting!

  For an application using bluetooth low energy, a Nordic NRF52840 turned out to be the winner.

    Not the newer more energy efficent nrf54 series?

      Ooh I'll take a look! Sometimes I get behind the times because I have to find a favorable dev board.
