During debug, I have my LoRa V3 connected to my laptop and running qty=3 DS18B20 one-wire temp sensors. When I disconnect the usb-c cable from my laptop and get power from a portable Anker type power pack, I see the one-wire signal no longer goes low (all the way to ground) - signal is fine when powered from my laptop, but any other power-only packs cause the one-wire to not go all the way low. I have tried about 5 different commercial power packs with the same results. We have tried a number of different cables - all with the same results.
We don’t see this on Wifi Kit 32 V2 boards… those work fine with portable battery packs…
Any guidance would be appreciated.
