Is that version of GPS module supported in the version of PX4 you are using? Is it wired properly to your flight controller as well?

RE: Unable to run Voxl-portal
You need to point to the IP address of your VOXL. Typing
ifconfig
should show you that information -

RE: How to receive GPS information in voxl-tflite-server?
Hello @Nguyen-Tien-Su,
voxl-inspect-gps (https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-mpa-tools/-/blob/master/tools/voxl-inspect-gps.c) is an example of how to subscribe to the gps pipe and process the data.

RE: VOXL-2 Reject position control error
We ship the Sentinel configured to fly outdoors using GPS positioning so that may be the reason for VIO not working for you. All you should have to do is load our EKF2 indoor/vio params. I'll drop a link to where you can find all relevant param files and helper files such as the ekf2_indoor_vio.params that you need.

RE: ARDUPILOT VOXL CAM ORIENTATION ISSUE ?
Hi,
Looking at the difference between the default imu1 to tracking :
{ "parent": "imu1", "child": "tracking", "T_child_wrt_parent": [-0.0344, 0.03, 0.005], "RPY_parent_to_child": [-45, 0, 0] }
and yours:
{ "parent": "imu1", "child": "tracking", "T_child_wrt_parent": [-0.0614, -0.08, 0.005], "RPY_parent_to_child": [0, 0, 0] }
You seem to have indicated that the camera has moved 3cm in x direction and 11cm in y, which doesn't seem correct based on how far you've moved the camera, so it's probably an extrinsics issue causing this.

RE: what is the ESC signal to control the motor?
Hello,
Are you asking about ModalAI ESC? You can find information at https://docs.modalai.com/modal-escs/ and https://docs.modalai.com/modal-esc-v2-manual/. Please see information about V2 (V1 is obsolete). To answer your question about communication, the ModalAI ESC accepts control input via UART. The interface is implemented in PX4, you can find more information here https://docs.modalai.com/modal-esc-px4-user-guide/ and https://github.com/modalai/px4-firmware/tree/modalai-1.12-dev/src/drivers/uart_esc/modalai_esc.
Actuator Controls should be available to log via PX4 which would the the commanded RPM sent out the motors.
What Drone platform are you using and can you confirm that you have the ModalAi ESC V2?
Please review the documentation and let us know if you have other questions.

RE: Pre-arm check failed
Hi @yu-zhang ,
Short answer: we don't use that button/switch, and 22027 disables the FW from requiring it (as far as I know).
As we use a 6-pin JST connector for our GPS connector, and don't route the actual switch/button line from the mast down to the board, there's no way for that to actual work with the 6-pin version.
Our firmware by default sets that 22027 value to make it so we don't need to press the button (since the wire doesn't actually route, you'd need the 10 pin GSP to do that...).
If someone needs to use this feature, the pin is exposed here instead: https://docs.modalai.com/voxl-flight-datasheet-connectors/#j1011---i2c2-safety-button-input

RE: cannot connect usb camera over USB - C adb port
Thanks for the logs @Jagatpreet-Singh-Nir , we'll need to dig into this. It seems like it's not being detected, we attempted a different device an believe to have replicated what you're seeing. We'll reach out with updates as we have them. Thanks!
