    • RE: RB5 motor does not spin even after successful arm

      @Adrian-Hidalgo

      Thank you for your patient!

      Recall the changes between spin and no-more-spin is active VIO and VOA services while indoor. Then disable both VIO and VOA service, but motor no longer spin after reboot.

      Finally found a solution without flashing the system image:
      Step 1: load https://gitlab.com/voxl-public/flight-core-px4/px4-parameters/-/blob/master/helpers/rb5/ekf2_outdoor_gps_mag.params
      Step 2: set vehicle param COM_ARM_WO_GPS to 1
      Step 3: power cycle RB5

      Now arm RB5 after it comes back online, motor spins. -:)
      Hope this helps anyone else running into same issue.

    • RE: RB5 motor does not spin even after successful arm

      @Adrian-Hidalgo

      thank you for your notes.

      Double check the cable from RB5 to ESC per https://docs.modalai.com/images/rb5/rb5-labeled-3.png . The cable is plugged on both ends.

      Yes, dx6e is the transmitter. Did load indoor helper (https://gitlab.com/voxl-public/flight-core-px4/px4-parameters/-/blob/master/helpers/rb5/ekf2_indoor_vio.params) and dx6e helper (https://gitlab.com/voxl-public/flight-core-px4/px4-parameters/-/blob/master/helpers/rb5/spektrum_dx6e_config.params).

      Also did load single platform file (https://gitlab.com/voxl-public/flight-core-px4/px4-parameters/-/blob/master/platforms/v1.12/RB5_Flight/RB5_Flight_V1_param_rev_A.params).

      After load above three files, we power cycle RB5 and still no motor spin on ARM.

      Question is why we need to flash system image after loading platform file? Is this a routine thing we need to do with any platform file loading? Or we flash system image for troubleshooting purpose?

      Any method (such as wavros?) to create the missing DSHOT_TEL_CFG ? Why would reflash system image create such missing parameter?

      Hi @modaltb

      https://gitlab.com/voxl-public/flight-core-px4/px4-parameters/-/blob/master/platforms/v1.12/RB5_Flight/RB5_Flight_V1_param_rev_A.params has


      ################################################################################

      Motors/ESCs

      ################################################################################

      disable dshot, use uart instead

      1 1 DSHOT_CONFIG 0 6
      1 1 DSHOT_TEL_CFG 0 6

      =============

      Looks like DSHOT_TEL_CFG is related to Motors. So missing that from PX4 probably relate to the no-motor-spin issue here.

      How do we add this PX4 param? How could this parameter be missing?

    • RE: RB5 motor does not spin even after successful arm

      Hi @modaltb
      When vehicle is armed, there is another message showing on the QGC. The message is

      Failsafe mode activated

      Then there is no motor spin.

      When going to QGC->Vehicle Setup->Safety, another message shows "Missing params: 1:SDLOG_MODE"

    • RE: RB5 motor does not spin even after successful arm

      Hi @modaltb
      The vehicle was powered via benchtop/AC adapter. We have tried 4S battery as well now. Still no-motor-spin when ARM even when vehicle is battery powered. Under either powering method, the blue LEDs on the ESC always flashing.

      There is a failure when loading https://gitlab.com/voxl-public/flight-core-px4/px4-parameters/-/blob/master/platforms/v1.12/RB5_Flight/RB5_Flight_V1_param_rev_A.params

      The error message is
      Parameters are missing from firmware. You may be running a version of firmware which is not fully supported or your firmware has a bug in it. Missing params: 1:DSHOT_TEL_CFG

      Looks like DSHOT_TEL_CFG does not exist on the vehicle. How do we create this missing parameter? Does this parameter have anything to do with motor spin?

    • RE: RB5 motor does not spin even after successful arm

      On MAVLink Console, type
      modalai_esc

      no response from vehicle's system shell.
      Is this normal?

    • RE: RB5 motor does not spin even after successful arm

      After rebooting RB5, MAG #0 error msg is gone.

      Still no motor spin after a successful ARM.

      Another question is on vehicle setup, which sub-type should be selected for RB5? Generic Quadcopter?

      QGC does have warning messages:

      MAG #0 failed: TIMEOUT!

    • RE: RB5 motor does not spin even after successful arm

      May not be related. Does each unit of RB5 store a copy of its unique factory calibration data (such as compass, etc.) on its file system so that we can always restore such factory parameters? If so, where is path of such data?

    • RE: RB5 motor does not spin even after successful arm

      Does the example of communicating ESC over UART in the video ( https://www.youtube.com/watch?v=4cXsuSaW-3k&t=66s ) require some sort of UART adapter?

      Any other way to isolate the no-motor-spin when armed issue?

      Previously, the same RB5 was spinning motors when armed right before setting

      • rb5-qvio-server-configure to yes
      • rb5-voa-server-configure to yes

      However, since then we have set both qvio and voa back to disabled, then reboot RB5, still have this no-motor-spin issue.

    • RE: RB5 video streaming does not show up on QGC

      RB5 is on 5G; openvpn in between RB5 and QGC host.

      QGC host is running Ubuntu 22.04 LTS.

      QGC host can ping RB5 ipv4 10.8.0.x where x is RB5

      Run VLC on QGC host and results in same error where VLC can not play rtsp://10.8.0.x:8554/camera3

      RB5 has rb5-streamer.service active running:

      qrb5165-rb5 systemd[1]: Started rb5-streamer.
      qrb5165-rb5 rb5-streamer[2470]: [INFO] RTSP stream ready at rtsp://VEHICLES_IP:8554/camera3

    • RE: Spectrum failed to enter binding mode

      Indeed, my bad, early RB5 has RC version 1.0. Bind successfully now after connecting AR6210 manual bind satellite. Thank you, Chad! Thank you, Adrian!

    • RE: Spectrum failed to enter binding mode

      RB5 does not look like have binding board and Spektrum RC is v1.1 per https://docs.modalai.com/Qualcomm-Flight-RB5-user-guide-pre-flight-setup/ .

      If turn on DX6e first, then power on RB5, Spektrum has a blinking orange light. Then power off DX6e, Spektrum blinking orange light goes off right away. This state leaves DX6e no chance to do bind procedure.

    • RB5 motor does not spin even after successful arm

      ARM successfully but four motors do not spin. Was spinning yesterday.

      QGC->Vehicle Setup->Motors, slide to enable motor slider, then slide ALL motors to some level, expect motor spin under test mode but no motor spin.

      How to restore vehicle parameters back to factory default?

      What's the right sequence to load which files under https://gitlab.com/voxl-public/flight-core-px4/px4-parameters/-/tree/master/platforms/v1.12/RB5_Flight and https://gitlab.com/voxl-public/flight-core-px4/px4-parameters/-/tree/master/helpers/rb5

      Thank you!

    • RB5 video streaming does not show up on QGC

      Platform: Pro Dev Kit (MRB-D0004-3-V1-F1-B1-C11-M7-T1-K2) - Qualcomm Flight RB5 5G Platform Drone Reference Design and Quectel RM502Q-AE 5G Modem; RC radio version 1.1

      Software: full-flash of stock 1.0.5-M0052-9.1-perf-c, followed by installation of rb5-flight-sdk-1.1.3, then factory setting enabled

      Procedure:
      [1] Follow https://docs.modalai.com/Qualcomm-Flight-RB5-streamer/#rb5-streamer to enable rb5-streamer service
      [2] QGC side configure rtsp://HOST_IP:8554/camera3 where HOST_IP IPv4 address of Qualcomm Flight RB5

      No video shows up on the QGC side.

      Thanks.

      Software: full-flash of stock 1.0.5-M0052-9.1-perf-c, followed by installation of rb5-flight-sdk-1.1.3, then factory setting enabled

      Procedure:
      [1] The spectrum and DX6e are 10 feet apart. Both are powered off.
      [2] Power on Flight RB5 using AC adapter without battery installed. Over USB adb shell, issue command $rb5-bind -s
      [3] Expect spectrum blink with orange color, but see no light emit from spectrum; thus hold bind button while power on DX6e results in BIND Failure

      One thing is when DX6e power on without holding bind button, then spectrum starts blinking in orange after pressing bind button of DX6e a couple of time, but as soon as DX6e powers off, then spectrum stop blinking as well.

      Question: https://docs.modalai.com/Qualcomm-Flight-RB5-user-guide-pre-flight-setup/ failed to enter bind mode with RC version 1.1 hardware. How to resolve?

      Thank you.
