minus-squareprenatal_confusion@feddit.orglinkfedilinkEnglisharrow-up1·3 days agoI am aware of that but somehow expected that it still took more energy to receive until there are enough SATs available than to do a BLE scan. Just a gut feeling though and only receiving should have a bigger impact than I thought. Makes sense!
