How far apart can the pod and the pump be, and still communicate?
A few feet, I believe, although that’s hardly an issue since you usually have the PDM in your hand — and therefore close to the pod on your bod — whenever dosing or entering commands. The bigger issue is that you’ve got to have the PDM angled right (not too high up or facing the wrong way), otherwise you get a “pod status not available” message. Meanwhile, if you choose to leave the PDM behind while going off for a several-hour bike ride (my bad), the pump will continue to deliver whatever basal rate is programmed, even without the PDM being nearby. If you urgently needed to stop delivery, you can always just remove the pod.
