Hi! I have installed GRC3.8 and was working on BPSK based packet communication using LimeSDR. It doesn't seem o improve things much. All the packets that I receive are rejected due to errors in reception and header parser fails. I think it's the correlation estimation block of the AGC in the

Hi! Thanks for your reply. While I'll work on installing and working with GRC 3.8, I was just wondering will the over the air communication be bad enough to not even receive a single correct packet? Is it to do with loop_bw for FLL, PFB and Costas_Loop or the digital gain values (a multiply b

Hi SG, well, packets getting broken over the air is normal. That's what happens! Also, really, we've removed quite a bit of broken packet infrastructure in GNU Radio 3.8; you should really be using GNU Radio 3.8 and when starting to develop anything in this day and age. GNU Radio 3.7 is something

Hi! I have been trying to use the packet communication examples under gr-digital in GNURadio(v 3.7.14.0) on ubuntu machines with LimeSDR Mini for over the air communication.  I am using the usrp_packet_tx.grc and uspr_packet_rx.grc  to transmit and receive BPSK modulated packets respectively.
