    For our application, we want to power up the mDot every 5 or 10 minutes to transfer a small packet of data. Currently we are saving the session before each power down and restoring on power up.

    Looking at the datasheet for the STM32F411RET, the flash endurance is only specified to 10K writes, meaning our application is only good for a month or two if the session is stored in a single place in MCU flash.

    Is there anything in the firmware ensuring longer flash life for the session save/restore calls? What kind of endurance should we budget for?

    Thanks,
    –Bob

    I think I may have answered my own question:

    And in the developer guide: https://www.multitech.com/documents/publications/manuals/s000612_DB9.pdf

    SPI Flash
    Note: Using the SPI Flash, Micron M25P16 Family.

    I’m surprised this isn’t mentioned in the data sheet.
