Sending byte array over BLE using BluetothLE1 extension

Hi,
I'm trying to send a large list (of over 25 bytes) over an older version of BluetoothLE1, since I had troubles scanning for new devices on newer versions. Auth_list is the list I want to send. But the BLE stops sending after 20bytes.
How do I get all bytes sent properly.

Thanks in advance
