https://devzone.nordicsemi.com/f/nordic-q-a/37946/is-it-possible-to-disable-mcu-reset-behavior-when-using-mesh-stackHi I have implemented a controller device using nRF52832. The controller device is installed in an industrial control box where it is used to control relays that subsequently controls Magnetic switches. I tested two wireless communication options, i.een-USTelligent Community 13Wed, 29 Aug 2018 12:42:55 GMThttps://devzone.nordicsemi.com/thread/146310?ContentTypeID=1Wed, 29 Aug 2018 12:42:55 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2f629169-f47b-48ad-b9c8-f4fd0b5cc8a8run_ar<p>As Awneil says, you need to fix your hw.
