Hi, I am using the /usr/local/lib/uhd/utils/query_gpsdo_sensors to get gps information, but it shows: *Waiting for the GPSDO to warm up...........No response from GPSDO in 30 seconds*
This is the whole information: *hu@hu:~$ /usr/local/lib/uhd/utils/query_gpsdo_sensorsCreating the USRP device with: ...[INFO] [UHD] linux; GNU C++ version 7.5.0; Boost_106501; UHD_3.15.0.HEAD-0-gaea0e2de[INFO] [X300] X300 initialization sequence...[INFO] [X300] Maximum frame size: 1472 bytes.[INFO] [X300] Radio 1x clock: 200 MHz[INFO] [GPS] Found an internal GPSDO: LC_XO, Firmware Rev 0.929b[INFO] [0/DmaFIFO_0] Initializing block control (NOC ID: 0xF1F0D00000000000)[INFO] [0/DmaFIFO_0] BIST passed (Throughput: 1304 MB/s)[INFO] [0/DmaFIFO_0] BIST passed (Throughput: 1306 MB/s)[INFO] [0/Radio_0] Initializing block control (NOC ID: 0x12AD100000000001)[INFO] [0/Radio_1] Initializing block control (NOC ID: 0x12AD100000000001)[INFO] [0/DDC_0] Initializing block control (NOC ID: 0xDDC0000000000000)[INFO] [0/DDC_1] Initializing block control (NOC ID: 0xDDC0000000000000)[INFO] [0/DUC_0] Initializing block control (NOC ID: 0xD0C0000000000000)[INFO] [0/DUC_1] Initializing block control (NOC ID: 0xD0C0000000000000)Using Device: Single USRP: Device: X-Series Device Mboard 0: X310 RX Channel: 0 RX DSP: 0 RX Dboard: A RX Subdev: UBX RX RX Channel: 1 RX DSP: 0 RX Dboard: B RX Subdev: UBX RX TX Channel: 0 TX DSP: 0 TX Dboard: A TX Subdev: UBX TX TX Channel: 1 TX DSP: 0 TX Dboard: B TX Subdev: UBX TXSetting the reference clock source to "gpsdo"...Clock source is now gpsdoSetting the reference clock source to "gpsdo"...Time source is now gpsdoWaiting for ref_locked...USRP Locked to Reference.**************************************Helpful Notes on Clock/PPS Selection**************************************As you can see, the default 10 MHz Reference and 1 PPS signals are now from the GPSDO.If you would like to use the internal reference(TCXO) in other applications, you must configure that explicitly.****************************************************************************************************************Waiting for the GPSDO to warm up...........No response from GPSDO in 30 seconds* I do plug the GPSDO to the board, and I plug the 5V active GPS antenna in the `GPS ANT` connector at the rear panel. But I am not sure why. I just want to get the location information. (btw, is it because I am in the indoor area?)
