[srslte-users] Hi,I want to ask how to run srsLTE on USRP N310

[zhouming]

Hi, all,

I tried the srsLTE(UE) 19.06 with UHD 3.13.0.2 on N310, but it failed to connect to the LTE network.
There are two failure situations with the TX/RX offset = 45 samples, and I donnot know how to fix it.
(Because there is no settings of TX/RX offset for N310 in function void radio::set_tx_srate(double srate) of srsLTE code, so I set the time_adv_nsamples to 45 in configure file directly)
What the correct value for time_adv_nsamples??
Could you help me?? thank you very much.
