Thank for you fast reply and help.
I change the EARFCN to 890(1959 MHz), but I still get the same error.
I have seen some sample output that get from srsENB, and the previous post,
is the SNR usually =0 normal ?
In my situation, the SNR become none 0 only after connection establish, and
it will soon become 0 again.
The log is like below.
And I have also tested one computer runs epc and enb, the other one runs
"srsLTE/build/lib/examples/pdsch_ue -f 1959e6 -r 0x1234" that I have seen
in previous post, I'm not sure this usage is correct or not.
The SNR is almost over +20 dB, is that normal condition ? If it's true,
then why the SNR on ENB usually 0.
The "pdsch_ue" log is like below.
Thanks for your help again.
