How to retrieve data?

Can I retrieve data from the digital hemoglobin meter poc-30 point of care device via Bluetooth using react-native-ble-manager, or do I need to use Android code?

An example how i read data :

function readIfActivated() {
  const serviceUUID = "19b10000-e8f2-537e-4f6c-d104768a1214";
  const characteristicUUID = "19b10001-e8f2-537e-4f6c-d104768a1215";

  BleManager.read(antivolID, serviceUUID, characteristicUUID)
    .then((readData) => {
      console.log("Read data: ", readData);

      const isActivated = readData[0] === 0x01;

      setIsAntivolActivated(isActivated);

      console.log("Antivol activated state: ", isActivated ? "Activated" : "Deactivated");
    })
    .catch((error) => {
      console.log("Error reading antivol state: ", error);
    });
}

@wysixontheflux Is this serviceUUID and characteristicUUID static or dynamic? If they are dynamic, how do I obtain them?

Having the same problem. Were you able to read the data with this library or did you use the android code?

[lalit-suthar-dev]

@aminhaerijs Yes, I used Android code.

Do you have a solution for iOS as well?

[lalit-suthar-dev]

@aminhaerijs Solution is only for Android as the device does not support iOS.
