I searched the forums a bit, but could not find the answer. Is it possible to log the data on GMC-500+ while the counter is not connected to WiFi and then, once connection is available to upload the data? This way there are no gaps in the log.
Thanks EmfDev! The workaround would be to switch to cell phone's hotspot wi-fi SSID while normal wi-fi is not available. It will require to set hotspot SSID name/password the same as "home wifi", otherwise one will have to re-enter both values every time - pain.
Is there a "feature request" page for counters where people can submit their ideas?
