@Chad-Sweet My region operating bands in India are 4,30 and 1. All these bands match with modem since I was using the modem since past few months successfully. All of sudden it has stopped working.
What inference can we derive from above logs? My region code are getting fetched correctly but registration isn't happening for Sim cards. I have tried multiple sim cards as well but no success.
Can it be hardware issue?
Is there any way to factory reset modem?
How to debug this further?
@Chad-Sweet Please help on this one. I am urgently in need of this to work.
Hello,
My system version on VOXLCAM is 3.8.0. I am facing issue where my modem is not able to connect to my country's LTE network. We have V2 LTE Modem installed on VOXLCAM which was working perfectly from past few months and all of a sudden it stopped working.
I am attaching logs of voxl-modem service for your reference. I have also verified my APN for this Sim card and properly configured it via voxl-configure-modem service. Also I am using voxl-modem system startup service for starting modem on bootup and connecting to LTE network.
voxl:/$ journalctl -u voxl-modem.service -f

Expecting for quick help on this issue.
Hello,
I am using system image 3.8.0 on VOXLCAM. I am integrating ModalAI ESC V2 on my multi-rotor platform and I was curious if I need to perform ESC calibration with QGC or with Voxl-esc calibration tool before procedding with full loop execution?
Let me know.
@Chad-Sweet I have GPS mounted over VoxlCam hardware with distance of approximately 10 cms. I also tried moving GPS towards backside similar to seeker but still I wasn't able to get fix. I have waited for an hour to get fix but still facing issues. Do I need to configure GPS module by any chance with u-center : https://www.u-blox.com/en/product/u-center ?
As far as electromagnetic interference is concerned I don't think there is anything in very close vicinity of GPS.
Hello,
My system image on VOXLCAM is 3.8.0 and px4 firwmare version is Modalai 1.11.3-0.2.3. I bought ublox M8N GPS from here. I wanted to try GPS + VIO based ADFS flight in outdoor and indoor environment.
I am unable to get 3D fix for my GPS. I have correctly set parameter GPS_1_CONFIG to GPS_1 and also connected GPS to J10 connector on flightcore. My EKF2_AID_MASK is set to '1' for GPS only flight. I am constantly getting BLUE LED blinking which means no GPS fix. I am trying this outdoor with clear sky view.
Here is my Nuttx QGC logs and GPS status
I also tried cold, warm and hot reset but without any luck.
Any help in further debugging would be highly appreciated.
@Chad-Sweet Here's QVIO Overlay snapshot. I do get odometry initially correctly but in-flight there was uncontrolled drift. Also let me know about following :
@Chad-Sweet Thank you for the response. I will update qvio overlay as well.
Just a quick question, Can the calibration fix blurry image on tracking camera? Do we also need to manually refocus lens just like for stereo camera with 6mm wrench?
Hello,
I am running system image 3.8.0 on VOXLCAM. I had few crash flight on VOXLCAM due to uncontrolled drift when working in VIO mode. Setup was working fine till I had crashes due to my propulsion system not being stable. But now everything is stable except QVIO.
I suspect tracking camera image has became blurry as you can see in below picture due to some impacts or crashes.
Can this uncontrolled drift be because of blurry tracking camera image? How to solve this problem?
Do I need to recaliberate camera?
What are standard procedure post crash which we need to follow to avoid uncontrolled drift?
@tom I don't see wwan0 interface after doing ifconfig so couldn't ping google.com as well.
