LTE_DL_RECEIVER NOT DETECTING ANY CELLS

[ivyselly]

Hi,
I am running the LTE_DL_RECEIVER function on ubuntu 20.04 using usrp b210 zero.
so i use the matlab hSchScanLTEWaveformGUIanLTEWaveformGUI gui to search for cells in a given band width, and it is able to detect cells, also i use srsue and i am able to find and connect to cells in that same lte band(3), aslo using the srsran cell_search test, multiple cells are detected in the band as seen below

however, when i use the get_signal_from_sdr funtion with these parameters: get_signal_from_sdr('usrp', 1840e6, 50e6, 30.2e6, 1, 40, 80)

i get the results that no cell is found after running the LTE_DL_RECEIVER

any help or directions would be appreciated.
