Thank you for your reply.
I know this document.
I can receive the AR_AS_Notifications packets,but I do not know how to send AR_ACK packet to AP.Because I do not know the form of data that should be signatured by HMAC-SHA1 . How to creat AR_ACK packet.I had try a lot of methods(program a lot of code)but no one can match the signature created by AP.
Here is the directy copy & pase from documentation "Integrating with the RTLS data feed"
------------------------------------------------------------------------------------------------
my $packet = pack($self->header_pack_str,
$rtls_data{code},
$rtls_data{id},
$rtls_data{major_version},
$rtls_data{minor_version},
length($rtls_data{payload}),
Mercury::Utility::MAC->text2bin($rtls_data{target_mac}),
"\0\0",
-------------------------------------------------------------
Can you tell me what is the content of $self->header_pack_str ??
Have solved the problem? Can I get your solution?Or you can give me an example about the AR_ACK packet?? Thank you.
