after setting the osmo-bts-trx and osmo-trx-uhd and with a BLADERF X40 ,i just got this when running my network ! every other services like HLR,MSC...work perfectly and just the osmo-trx-uhd have some problems with the bladerf ! osmo-trx-uhd.service - Osmocom SDR BTS L1 Transceiver (UHD Backend) Loaded: loaded (/lib/systemd/system/osmo-trx-uhd.service; disabled; vendor preset: enabled) Active: failed (Result: exit-code) since Mon 2019-10-21 20:04:25 CET; 5min ago Process: 20384 ExecStart=/usr/bin/osmo-trx-uhd -C /etc/osmocom/osmo-trx-uhd.cfg (code=exited, status=1/FAILURE) Main PID: 20384 (code=exited, status=1/FAILURE) Oct 21 20:04:24 osmo-trx-uhd[20384]: -- setSampleRate(Rx, 0, 4.000000 MHz), actual = 4.000000 MHz Oct 21 20:04:24 osmo-trx-uhd[20384]: -- setSampleRate(Tx, 0, 4.000000 MHz), actual = 4.000000 MHz Oct 21 20:04:24 osmo-trx-uhd[20384]: Mon Oct 21 20:04:24 2019 DDEV <0002> UHDDevice.cpp:355 [tid=140004723987136] Unsupported device bladeRF Oct 21 20:04:24 osmo-trx-uhd[20384]: Mon Oct 21 20:04:24 2019 DMAIN <0000> osmo-trx.cpp:514 [tid=140004723987136] Failed to create radio device Oct 21 20:04:24 osmo-trx-uhd[20384]: Mon Oct 21 20:04:24 2019 DMAIN <0000> osmo-trx.cpp:485 [tid=140004723987136] Shutting down transceiver...
