client.GetData(trama, rd, new GXReplyData()) false though frame received is correct

Hi all,

I'm trying to comunicate with my smart meter locally but sometimes when I receive frame and try to do "Client.GetData(p.Reply, reply)" to decrypt the frame, this method return false and I receive in system console "Invalid HDLC Frame: 52. Expected: 32", though frame I received is correctly decrypted.

(Now I'm not using "void ReadDataBlock(byte[] data, GXReplyData reply)" because I don't understand the method Client.ReceiverReady(reply.MoreData), but I'm only using Serial.Send() and Serial.Receive().)

An example:

<- 03:49:44.854 Sent 7E A0 2E 02 21 03 32 0C 2E E6 E6 00 DB 00 1E 30 80 00 01 02 BE B4 68 6B DC B5 90 85 48 E9 49 09 58 96 E8 6D 07 61 F9 26 02 1E 27 D1 C0 96 DB 7E
Decrypted Frame: (C0 01 C1 00 01 00 00 5E 27 14 FF 02 00)

and I receive

Invalid HDLC Frame: 52. Expected: 32
