The FreeStyle Libre 2 Plus sensor sends readings to your t:slim X2 insulin pump every 1 minute. Control-IQ technology adjusts insulin delivery every 5 minutes.
When the FreeStyle Libre 2 Plus sensor is connected with your t:slim X2 insulin pump, the numerical sensor glucose value on your pump and t:connect mobile app will update every 1 minute. The sensor graph values on your pump and app will be updated every 5 minutes.
Please note that if your pump and app lose connection, you will notice a gap in your sensor graph, as data will not backfill.
