Automation API for CATC Bluetooth Analyzers CATC Ver. 1.40
2.4.9 ITrace::GetPacket
Retrieves raw packet representation
Parameters
packet_number - number of packet to retrieve
packet - raw packet representation
number_of_bits - number of bits in raw packet representation
Return values
ANALYZERCOMERROR_INVALIDPACKETNUMBER - specified packet number is invalid
Remarks
“ Packet ” parameter has VT_ARRAY | VT_VARIANT actual automation type. Each element of
this array has VT_UI1 automation type. Since the last element of the array may contain
extra data, you need to use number_of_bits parameter to determine actual packet data.
Example
VBScript:
<OBJECT
ID = Analyzer
CLASSID = "clsid:0B179BB3-DC61-11d4-9B71-000102566088" >
</OBJECT>
<INPUT TYPE=TEXT NAME="TextPacketNumber">
<P ALIGN=LEFT ID=StatusText></P>
