@Alex-Kushleyev Alright, thanks for the info

Hi @xiangfuli Did you arm your drone with the wall power supply?

@Alex-Kushleyev Hi Alex, awesome! - and that's a good question. We don't know necessarily where the text will be in the image beforehand, so do we have to look for it. On the other hand, looking for text and reading it are two different stages - so we are planning to try a pipeline where we first find text at a lower resolution/lower quality and then process selected crops with more resolution and/or processing. So, in short, debayering only selected parts of the image is something that we are interested in, but we only know what regions to process at runtime, not before we look at the image. If debayering selected regions is possible that's something we are definitely interested in. Thanks!

@kcmacauley , the voxl-esc driver is implemented in PX4, so you can see how the data packets are generated to send RPM commands and receive the feedback from each ESC. https://github.com/modalai/px4-firmware/blob/voxl-dev/src/drivers/actuators/voxl_esc/voxl_esc.cpp#L1230 https://github.com/modalai/px4-firmware/blob/voxl-dev/src/drivers/actuators/voxl_esc/voxl_esc.cpp#L1252 Also, an outdated implementation, which you can also refer to, can be found here : https://gitlab.com/voxl-public/support/esc-driver -- it can be compiled and tested standalone, but we do not maintain or support it. Our voxl-esc python tools provide a lot more functionality, but not entirely open source : https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-esc Finally, an even more outdated (but more formal) document can be found here : https://developer.qualcomm.com/qfile/34042/80-p4698-19_b_qualcomm_snapdragon_navigator_esc_protocol_spec.pdf. Also, not supported or complete, but can be used as a reference. If you have any specific questions about protocol, I can answer, but you should be able to get what you need for basic flight from the PX4 driver. For offline testing and tuning it is best to use the voxl-esc python tools. Alex

@tahawaru I like using Google Fi, super easy to setup

hey not sure if this is an @tom or @modaltb inquiry, but when following the steps for the kernel build guide, stuff is off with the drone. It boots up and I can adb fine, but there are issues with the wifi, similar to another post Tom helped me with two weeks ago, but for definitely not the same hardware-related reason. The wifi adaptable does not turn on and when you run voxl-wifi the mac address is undefined. I remember stepping through those scripts while troubleshooting the hardware issues and recall that script queries to find its mac address, which must be returning something invalid. I have tested this with both of my drones. I can very easily flash them back with https://docs.modalai.com/sentinel-factory-reset/ and they operate as expected. While my desire is to edit part of the usb driver scripts, the kernel I am attempting to put on the drone is the unchanged version following the steps here https://docs.modalai.com/voxl2-kernel-build-guide/. The only deviation from the guide is that the guide is written for SDK 1.1.3. I have put 1.3.0 on both of my drones, and from my understanding the docker scripts pull the default branch of each repo which has the same commit tags as 1.7.8. I have included the output of dmesg for both the 1.3.0 image available from the downloads page, and the results when following the custom kernel build steps. https://drive.google.com/drive/folders/14L5gLbAOfF2OcSW2rHFTI4VIoREkTCFJ?usp=sharing

@rdjarvis , I received the M0138 ESC that you sent back (reported that you were unable to communicate with the ESC). The issue was that the baud rate in ESC params was set to 2.5Mbit instead of 250K by accident, so our auto-scan in ESC tools could not detect the ESC (and VOXL2 DSP does not support 2.5Mbit). We will fix this in future ESC firmware to prevent accidental setting of unsupported baud rates. Sorry about that. Alex

@H-AL , are you using voxl-camera-server to produce h264 / h265 stream or voxl-streamer, which is capable of accepting uncompressed frames and producing h264/h265 stream. voxl-streamer is also capable of taking a compressed stream from voxl-camera-server and exposing it via RTSP. Please clarify how you are setting up your streaming.. Thanks! Alex

@Alex-Kushleyev This forum post can be considered resolved with this answer: https://forum.modalai.com/post/17782 Thanks for the update. Cheers!

@tahawaru We have never tried that. But according to the Quectel product documentation it seems like it should be possible. Of course you would need to attach a suitable GNSS antenna to it. And if you want to use that with PX4 then you would need to create a new driver for it.

@wilkinsaf , yes, you got it. By the way, you did not have to restore the old firmware, you could have just done this: ./voxl-esc-upload-firmware.py --firmware-baud-rate 57600 -f firmware/modalai_esc_firmware_m0117_1_v0_39_RC10_eb6fb500.bin --id 0 The following note does not really help, if you also have power connected to VOXL2.. WARNING: Specified ESC ID not detected; perform manual power cycle now However, if the ESC is connected to a PC, you can just power cycle the ESC and the the bootloader will start up and firmware update will being. Alex

@Alex-Kushleyev Thanks! This is helpful. Definitely easier to overheat these than the last gen so good to have the specs on it.

@groupo em9191 should work for you

@Gyeongmin-Kim We don't have any great insight at this point. Those sensors are new. It looks like you are seeing some ghosting. You could try different frame rates or exposure times to try and minimize the artifacts

@Aaky Should be fine. I fly with actual RC in HITL all the time.
