encode & send an att message If (op-code type == ATT_OP_TYPE_REQ) process the response with callback function see att_opcode_type_table (att.c) for opcode type definition

Parameters

att	structure of the communication channel
opcode	att message op-code
pdu	protocol data unit buffer
length	size of pdu
callback	callback function depending on opcode to process response
user_data	request data when relevant
destroy	function to manage user_data

Returns: att message sequence number or 0 if error
