Hi All,
I would like to change the center freq of my UHD Sink depending on who the
receiver is. So I wrote a custom block that will read what the destination mac
address is for a packet, and send a message to change the center freq based on
what destination address it is. This is the format for how I write the message:
{
message_port_register_out(PDU_PORT_ID);
}
.
.
.
command = pmt::make_dict();
command = pmt::dict_add(command, pmt::mp(“freq”),
pmt::mp(2.412e9));
command = pmt::dict_add(command, pmt::mp(“chan”), pmt::mp(0));
message_port_pub(PDU_PORT_ID, command);
I saw from other mailing list posts, that this was the syntax they used, but I
can’t get it to actually the center frequency. Is there something I am doing
wrong? I am using uhd version 3.10 and GRC version 3.7.11.1.
Thank you!!
