How CGM Data Is Collected

Sampling Frequency andd Accuracy

CGM sample glucose approximately every 1 to 5 minutes, generating hundreds of readings per day.

Bluetooth Low Energy (BLE)

Bluetooth Lower Energy is mess most most protocol for transmiting CGM data frem te transmitter te smartphone or receiver. BLE is chosen for it lowpow consumption, which allows the transmiter to lact for months on a small battery. The transmissionon range e is typically about 10- 30 feet, dependiing on obsacles and thee specific BLE chipset. BLE connections can ben be interted by walls, distance, or interference from wirelyss devices.

Near Field Communication (NFC)

Some CGM, such as te FreeStyle Librie serie, use NFC as te primary communication for the sensor- reater link. With NFC, the user must actively swipe thee reade or smartphone over thee sensor to get a reading.
