我想从这个类中取出字节值,以便我可以解析它,或者如果它可以解析它并获得第5和第6个字节值。
private void broadcastUpdate(final String action,
final BluetoothGattCharacteristic characteristic) {
final Intent intent = new Intent(action);
// This is special handling for the Heart Rate Measurement profile. Data parsing is
// carried out as per profile specifications:
// http://developer.bluetooth.org/gatt/characteristics/Pages/CharacteristicViewer.aspx?u=org.bluetooth.characteristic.heart_rate_measurement.xml
if (UUID_HEART_RATE_MEASUREMENT.equals(characteristic.getUuid())) {
final byte[] data = characteristic.getValue();
if (data != null && data.length > 0) {
final StringBuilder stringBuilder = new StringBuilder(data.length);
for(byte byteChar : data)
stringBuilder.append(String.format("%02X", byteChar));
intent.putExtra(EXTRA_DATA, new String(data) + "\n" + stringBuilder.toString());
} else {
// For all other profiles, writes the data formatted in HEX.
}
}
sendBroadcast(intent);
}
这是如何工作的,我踩到一个刻度,它发送给我这些字节:
00 00 00 00 02 02 00 00 00 00 00 00 00 00 00 00
存储在变量'数据'。我该如何处理数据'出去在另一个班级使用?
权重数据位于字节5和6上。如果转换字节5和6的十六进制值,则该示例中为' 0202
'十进制为514(51.4千克)。
我需要将字节数据用于另一个类来获取kg数据。我该怎么做呢?
