[QUOTE="Charlie27530, post: 2546576, member: 559302"] Your Glucose Meter Reader or the Phone app will not display a glucose reading until 60 minutes elapses after the first scan of the sensor with the Libre hand scanner or your phone with the Libre app. After that initial delay time, my experience with multiple sensors, but not all has been the Libre handheld scanner will irregularly display, "a reading is not available and to try again later." Usually there is a time delay displayed to wait before trying to scan for a reading again. Some sensors operate two weeks without encountering such messages, others are so frequent, I gave up and start a new sensor. The one thing I notice about sensors that are problematic, they frequently are accompanied with loss of blood following placement. This manifests as blood dripping from the sensor for a minute or so. More frequent occurrence of the error messages when attempting to read the sensor over the following days is correlated with the amount of blood loss. Increased blood loss correlates with increasing frequency of read errors. I can find no rhyme or reason for why hemorrhaging occurs with some sensors and not others. Over the last few years the frequency of error messages declined dramatically as did the frequency of blood loss when placing a new sensor. I assumed my placement technique had improved or Abbot had improved production processes. Whatever, the issue abated. Upon buying a compatible phone, the Libre App was installed. About six weeks back the phone app began alerting it could not communicate with the sensor (Loss of Signal alert). Initially it seemed it was a distance problem as the alert was occurring when I would leave the phone at one end of the house and working at the other. Then during the night with the phone on the nightstand, the alerts started to occur. Scanning the sensor, and other efforts to stop the maddening intermittent midnight warnings of doom failed. Some nights all went well and the phone could be left at a distance without a sudden doomsday alert sounding. Other nights were sleepless or I walked around through the mall beeping like R2D2. One thing that decreases the frequency of the problem is to close out the app, shut the phone off and restart the phone. Do not use the warm restart, shut the phone down. Soon as the phone is ready, launch the Libre app and scan the sensor. This does not entirely stop the problem with "Loss of Signal" but seems to reduce the frequency of occurrence on my phone. Also when the phone vendor pushes out new OS and Security updates, I recommend shutting the phone down after the update and restarting it from a known state. Again this helps reduce my occurrence of unwanted alarms, but does not entirely eliminate it. At least the phone only goes off every few hours versus every 10 minutes. When in meetings and not wanting to be disturbed, I turn off the "Loss of Signal" alert in the phone app. This does not stop the "High Glucose", "Low Glucose", or "Urgent Low Glucose" alarms from sounding if the device is able to communicate with your phone,.
