Wao superb! you cleaned it out also. Yes it works. Thanks much.
But did you figure out what was the issue at the first place :)
I'm not sure. Maybe it was related to one of the Packet Pad blocks.
Since you resampled, you also changed the length of the frame, which
might have confused the block (the length tag at the start of the frame
didn't correspond to the length of the frame anymore).
I have another related question about the wireshark connector in
transceiver_OQPSK.grc. I see that wireshark connector gets input from two
different outputs.
One from pdu_out of IEEE802.15.4 MAC and another from rxout of IEEE802.15.4
OQPSK PHY
When I see the output pcap file i..e sensor.pcap, same packet is logged
twice. I realized this by observing their sequence number field, which
repeats two times for every broadcast frame.
Yes, in the loopback configuration it logs all frames twice. Once they
are sent and once they are received. The setup makes more sense when you
actually transmit frames over the air. Then you might want to log what
was sent and what was received.
In your simulations you probably know what you sent and are only
interested in which frames made it through. In that case, just remove
the connection from the sender to the Wireshark block.
Best,
Bastian
