depthai-core OAK-D-Pro-PoE sends no IMU data to host

OAK-D-Pro-PoE sends no IMU data to host

Open diablodale opened this issue 2 years ago • 12 comments

I just today noticed, my OAK-D-PRO-POE sends no IMU data to the host.

Setup

depthai-core v2.15.1
Microsoft Windows [Version 10.0.19044.1586]
VS2019 v16.11.11
oak-d-pro-poe sensor

Repro

clone, config, build depthai-core for x64, shared lib, Debug, all examples+tests
set env var DEPTHAI_LEVEL=info
Run examples/imu_gyroscope_accelerometer.exe

Result

No gyro/acc output to console. Only the device info reports

...

Expected

gyro/accel data output to console, and the info reports

Notes

My OAK-D has no problems with this.

This problem occurs in my own app, and then I saw the problem also occurs with the examples.

If I pause the example exe, I see that it is waiting in the call imuData = imuQueue->get<dai::IMUData>();

@diablodale please check out this PR: https://github.com/luxonis/depthai-core/pull/399 IIRC you have a pre-production unit which probably didn't go through IMU FW update

Mar 24 '22 19:03 SzabolcsGergely

🤹‍♀️ can I also use https://github.com/luxonis/depthai-core/issues/319#issuecomment-1003446759 ? Would be somewhat easier for me. fyi, the test script you also provided in that issue outputs nothing from this poe IMU. No imu part or firmware numbers.

woman_juggling can I also use #319 (comment) ? Would be somewhat easier for me. fyi, the test script you also provided in that issue outputs nothing from this poe IMU. No imu part or firmware numbers.

Yes, you can. Or better use this: https://github.com/luxonis/depthai-python/pull/515 and run any of the IMU examples. Easier to install a python lib.

No luck with your python tool that works on the OAK-D

It never finds the PoE sensor.

How could I use https://github.com/luxonis/depthai-python/pull/515? That requires i build both depthai-core and depthai-python. It is prebuilt somewhere?

Mar 24 '22 20:03 diablodale

@diablodale you can install the library from imu_firmware_update directly as:

python3 -m pip install -U --prefer-binary --user --extra-index-url https://artifacts.luxonis.com/artifactory/luxonis-python-snapshot-local "depthai==2.14.1.0.dev+682598dde411486e6fc7cb4f6222a1da2606fce0"

0.4.0 didn't have POE support back then.

@diablodale add imu.doFirmwareUpdate() to the script, it will do IMU firmware update. I will make this behavior automatic. Looks like we didn't test your beta board before shipping it out, sorry about that.

No problem on my beta board. I fully expect all types of odd behaviors from a non-production unit. Yes, I will add that to the python script.

I am interested in the length of time needed for the firmware update. I remember on my usb oak-d it was not "fast". It needed many seconds. That test utility I used has a UI and I could see progress so I was patient. Given this sensor is PoE, I suspect it will also be many seconds or more. The startup time (if automatic) will be substantially more than a user/customer expects. And there is no progress UI so they know to be patient. The user/customer ?might? think this is an error condition and ctrl-c, stop, kill, or disconnect the sensor....in the middle of the firmware update. Which I suspect is a bad thing.

Is that firmware update delay being considered and have a reliable/good solution for those customers that don't know to wait and interrupt the firmware update? I understand that my unit is beta and needs the firmware. I can also image a future where you need to make a firmware update for the production models which introduces the potential of interrupted firmware updates. 🤔

Firmware update is performed during factory calibration/test, so for production units it's not needed. It handles interrupt in the middle of firmware update, so it won't get bricked, and it also has progress report. It takes about 30 seconds.

I have low-confidence that Luxonis will never in the life of your sensors update the IMU firmware. This is based on the last ~20 years of tech industry that introduced a practice of updating their hardware with firmware/drivers.

I see no progress update callback API. Perhaps there is console logging (what log level?) but that leads to similar problems as #400 and #418. Since the update is considerable in length and the unit does not function correctly, I consider this an error condition like in those two related issues. The Device startup would throw with the "IMU firmware version detected: 3.2.13 differs from latest available: 3.9.7. Use 'imu.doFirmwareUpdate()' to update firmware to latest." message.

This allows the developer/app/IT to alert the user/customer of the situation and to prepare for that firmware update. Or...rollback to an earlier depthai version that does not need that firmware.

OAK-D-Pro-PoE now sends imu data. Unfortunatey, the accelerometer data is incorrect. Getting any data required upgrading the OAK-D-Pro-PoE firmware to v3.9.9. And it was tested using depthai-core v2.25.0 I'm closing this issue since (incorrect) data is now being sent by PoE and received by depthai-core. This issue does not focus on bad data
