I have recently installed OpenBTS-2.8 on a Banana-Pi (Processor: ARMv7) board for USRP N210 functioning. All the prerequisites including GNURadio, UHD were successfully built on the board prior to OpenBTS installation. With all configurations done, still there is a problem in the USRP connection.
I have configured MCC, MNC and ethernet IP connection. "ping 192.168.10.2" works fine. Once the ethernet connection is established and until "./OpenBTS" is executed, "uhd_find_devices" and "uhd_usrp_probe" detect USRP. After the execution of "./OpenBTS", surprisingly "uhd_find_devices" and "uhd_usrp_probe" do not detect the device and say "No device found..." ('ping' is still working though). The strangest thing is even at this stage, "./OpenBTS" works fine even at a re-run.
After all these drama, no ('range') network is detected by a properly configured mobile phone. (Note: We have successfully placed calls and SMS with almost same procedure using a PC instead of B-Pi).
I am bit confused here whether this is a deal of OpenBTS or GNURadio. Does the processor speed come in to play in this scenario?
Any valuable suggestions would be highly appreciated.
