LoPy Brownout detector trigered with last firmware .



  • Hi all ,
    i have 6 Lopy working nicely as BLE scanner with an ER17505 battery ( lithium 3.6V).
    Adding two more give me some problems.... with the last firmware and same setup (battery / program )
    the two LoPy just go into a reset loop with :

    Is there a way to lower the brownout level or any workarround for this firmware ?
    Can i downgrade the firmware anymore ( i saw that the last i flashed required a program update ) ?

    thank's in advance.

  • ok ,
    After flashing back to 1.6... no more problems.
    so 3.6V powered ( on 5V or 3.3V ) with this kind of battery issue a BDO with last firmware.
    Maybe this information can help others.
