Hellow fellows, I am using openlte_v00-20-05 for academic research and when executing the scanner application it gives me the following error as if I am setting the the clock rate to 100 MHz. **** ERROR ******* linux; GNU C++ version 6.3.0 20170516; Boost_106200; UHD_003.010.001.HEAD-0-gc705922a LTE FDD DL SCAN Please connect to control port 20000 gr-osmosdr 0.1.4 (0.1.4) gnuradio 3.7.10.2 built-in source types: file osmosdr fcd rtl rtl_tcp uhd miri hackrf bladerf rfspace airspy soapy redpitaya FATAL:...

Hi I recently formatted my system and installed last openlte which is 0.20.5. Then I looked up into the details of the update and it says: July 30, 2017: Version 0.20.5 is available. This version added two codeword support, refactored PUCCH channel decoding for 1, 1A, and 1B, added SR configuration index mapping, added libltecommon unit tests, and properly handling FI fields for multiple AMD PDUs in the LTE library, added helper functions and interprocess message queue support to the tools library,...

Hi Joe, I assume you tried both ways ... just in case: LTE_fdd_dl_file_scan.py -d int8 <your_file.bin> LTE_fdd_dl_file_scan.py -d gr_complex <your_file.bin> well with that said, I dont know what else to tell you :( How did you get those LTE samples? You can try LTE_fdd_dl_file_gen ... to get your LTE samples ... Cheers.

well I assumed this question is too dumb, so nobody answered to it, but if there is someone with some kind of doubts I had then I will advice to enable the pcap dumping (write enable_pcap 1) when running LTE_fdd_enodeb and after working some minutes with your phone (of course you first need to know how to configure your openlte eNodeB so your phone will want to attach to it), take a look on the wireshark file that usually gets stored on /tmp/LTE_fdd_enodeb.pcap file and start studying the UE-MME...

Hi Joe Here https://sourceforge.net/p/openlte/wiki/Test%20Captures/ you can download the sample and check it with LTE_fdd_dl_file_scan.py You can also check https://sourceforge.net/p/openlte/discussion/general/thread/54dfe6f3/ on how to run it. Cheers

Hi guys I was helping a friend to install openlte on his laptop and we got the error on the attached file after doing the make command. UHD and Gnuradio installation was done according to https://kb.ettus.com/Building_and_Installing_the_USRP_Open-Source_Toolchain_(UHD_and_GNU_Radio)_on_Linux And UHD version is 3.10 and Gnuradio 3.7.10. Also we first installed polarssl 1.3.0 version and then last mbedtls version from tls.mbed.org I should quote that cmake output is clean ... it claims not to find...

Hi Dylanger ... It seems that you are using your own LTE parameters to configure 127.0.0.1:30000 interface and also you are using a configured simcard of your own ... well maybe you can try to create a fake network with your operator parameters (use small tx_gain and inside a close environment, of course!), and see if you your phone detects OpenLTE signal. You can use your cellphone engineer mode or any appstore app to check LTE parametrs on your phone ... like the EARFCN that your cellphone is currently...

Hey guys, I am happy to write to ask for something different that how to sense OpenLTE on my phone ... I am at somepoint where I can configure the LTE enodeB and transmit its signal with USRP B210 and also sense it on my phone (I want to indicate that all my tests are done with lower gain and also on closed environments). There is an app called GMON where you can see the neighbour cells that the phone detects and yes I can see my OpenLTE network and also I have to say that that excercise creates...
