Voxl2 Spektrum Receiver error

[Eric Katzfey]

@Chase-Riley Looks like the data is stable. It just doesn't seem the protocol byte to a stable value. Very odd. But I would try a flight with it in a carefully controlled environment in case anything goes wrong. In the worst case it could go out of control and you might not be able to use the kill switch so be safe.

@Chase-Riley Here is a link to the transmitter we use: https://www.horizonhobby.com/product/dx6e-6-channel-dsmx-transmitter-only/SPMR6655.html

@Eric-Katzfey When getting everything tested to go out and fly I started receiving a failsafe for ESC failure. When we were working with this back in SDK 1.0 in this thread. I had the issue of the actuators tab not showing up in QGC. I can now see the actuators tab on SDK 1.1.2 however I can not test the motors and when I try to arm I receive ESC Failure message. I am not sure if this has something to do with the custom deb file like it did when I couldn't see the actuators tab.

I can upload firmware and params to the ESC fine. Running voxl-esc-scan.py returns no issues. Any thoughts?

@Eric-Katzfey I was able to solve the ESC issue. It was not linked to the Spektrum issue. After getting the ESC to function I was not able to control throttle on the air vehicle. I am able to calibrate the RC controller and set flight modes and so on. Everything seems normal until a arm the motors (testing in Stabilize). The motors arm and spin up but I am unable to change the speed on the motors with any input of the controller. I checked the Px4 RC params and all match previously good known params. I have inlcluded a snippet of running voxl-px4 -d with Spektrum sill with -v argument. I noticed there was another error with a different value and was also 32 bytes instead of the 16 bytes we have been seeing.

@Eric-Katzfey I am also getting my hands on a DX6e for me to test. I should be able to try that in the morning. I still would like to figure out the DX8 as well though since we already have a bunch on hand in our lab.

[Eric Katzfey]

@Chase-Riley Did you analyze the flight log?

[Eric Katzfey]

@Chase-Riley For the DX8 there are some configuration options on the transmitter. There is DSMX versus DSM2. That may need to be changed. Have you tried the different options yet?

[Chase Riley]

@Eric-Katzfey I have tried all of the options in the DX8. 11, 22 and DSM2, DSMX. They all seemed to produce the same results in the logs.

[Chase Riley]

@Eric-Katzfey Here is a voxl-px4 log while testing with a DX6e this morning. I was able to bind and calibrate no problem. I am just not able to control the motors. Flight mode and kill switch seem to be working fine. So seems to have the same behavior as the DX8 with a error in the log for 32 bytes and 0x00.

@Chase-Riley Huh, that still doesn't look right. When you calibrate you can move each stick and it shows properly in QGC? And listener input_rc shows the values moving properly when you move the sticks? What is the value of the parameter COM_RC_IN_MODE?

[Chase Riley]

@Eric-Katzfey yes, each stick moves correctly in QGC. listener input_rc shows all sticks move correctly. I have tested with COM_RC_IN_MODE set to 0 and 2 and both yield the same results.

[Eric Katzfey]

@Chase-Riley And they are mapped correctly such that throttle is on the stick you want? Can you do listener on manual_control_setpoint and see the throttle value move when you move the throttle stick?

[Chase Riley]

@Eric-Katzfey RC_MAP_THROTTLE is set to Channel 3, RC_MAP_YAW is set to Channel 4, RC_MAP_ROLL is set to Channel 1, and RC_MAP_PITCH is set to Channel 2.

Moving the Throttle and Yaw stick while running listener manual_control_setpoint shows Throttle and Yaw changing values as it should. It also shows that Stick movement goes TRUE.

[Eric Katzfey]

@Chase-Riley Then at this point I can't think of how the RC could be related to the motors not spinning up. Can you arm, try to throttle up a few times, then disarm and send us the px4 flight log?

[Eric Katzfey]

@Chase-Riley And you have tried to throttle up in manual flight mode?

[Chase Riley]

@Eric-Katzfey I have tried to spin the motors in manual mode as well with no change. I have included a drop box link with the px4 flight log you requested.

@Chase-Riley I'm having some others take a look at the log file. I'm kind of stumped at the moment.

[Chase Riley]

@Eric-Katzfey Please let me know what you or your team find. This seems to be the last hurdle to getting me to flight testing. I have a shipping deadline to make on Friday with this system.

[Eric Katzfey]

@Chase-Riley Seems like ESC param issue. Alex is going to respond with some suggestions.

[Alex Kushleyev]

@Chase-Riley , we have discussed and the data on the PX4 side looks ok so far, which leads me to believe there may be an error in ESC params, specifically the RPM curve calibration pwm_vs_rpm_curve_a0, pwm_vs_rpm_curve_a1, pwm_vs_rpm_curve_a2.

Please confirm that you performed the calibration (with propeller mounted on motor!) according to instructions here and updated the results (a0, a1, a2) params in your esc params xml file and sent it to the ESC ?

Also double check the min_rpm and max_rpm in your esc params
