Hi All. Can you wirelessly set an nPM1300 PMIC in Ship mode? Thanks

    Hi.

    What do you mean by wirelessly?

    To enter ship mode you need to send an I2C message, e.g:

    static const struct device *regulators = DEVICE_DT_GET(DT_NODELABEL(npm1300_ek_regulators));

regulator_parent_ship_mode(regulators);


    Note that ship mode entry only works if the USB is disconnected.

    Hi Andy.

    My application and its nPM1300 are completely sealed in a plastic case, and I need to set it in Ship Mode many times along its life cycle to prevent the battery from getting damaged by going below the Undervoltage limits. Obviously, I can`t use a wire connection to send the SHIP command because of the seal, but, could I rather send it wirelessly by air (OTA ?).
    The idea is to use nRF Connect for PC to issue the proper command and be able to reach the appropriate register in the PMIC, having in between an adaptor like your nRF52840 Dongle or equivalent to implement the physical OSI layer. As I mention, air in this case. Would this be possible?

    Many thanks for your guidance Andy.
    Best Regards,

    Juan
