如何使用android从BLE读取数据

Question

我开发了用于沟通BLE的演示应用程序。现在我可以用BLE读写数据了。当我读取数据的某些时候，我得到字符串一段时间，我得到这样的数据 final byte[] data = characteristic.getValue(); try { if (data != null && data.length > 0) { String messageString = new String(data, "UTF-8"); Log.v("MessageString", messageString); intent.putExtra(EXTRA_DATA, new String(data) + "\n" + messageString); } }catch (Exception e) { e.printStackTrace(); }

$modulare = $this->Database->prepare("
    SELECT id, titel, sorting, kuerzel
    FROM cc_produkte
    WHERE veroeffentlichen = 1
    AND kuerzel = ? // Here commas have to be filtered
    ORDER BY sorting, id ASC
")
->execute($pid);
