@chennz1 You can use J3 with an MCBL-00022-2: https://www.modalai.com/products/mcbl-00022 paired with a USB to ethernet adapter, we often use these ones: https://www.cablecreation.com/products/usb-3-0-gigabit-adapter-2-pack?_pos=1&_sid=57950aa19&_ss=r

hmmm, There is a similar (but not exactly the same) behavior with SPI on APQ8096 where all reads are preceded by a single random byte meaning libvoxl-io needs to read one extra byte than expected and then discard the first dummy byte. However this happens under the hood here:

https://gitlab.com/voxl-public/voxl-sdk/core-libs/libapq8096-io/-/blob/master/lib/sdsp/io_rpc_spi.c#L254

I've not seen such a thing with I2C. Have you looked at our VL53L1X driver for APQ8096? It might just work with your newer VL53L1CB sensors with small changes.

@doe43john77 Update: There is a program called voxl-configure-modem. All that needs to be done is select some options regarding the manufacturer of the 5G modem as well as the provider the SIM card is provisioned on.

For the -c which is telling the Voxl board which cameras to expect, choose either 3 or 7 depending on your camera config.

To all that might come across this, updating to OpenVPN 2.4.6 solved this issue. Note that a reset of the VOXL is required before the upgrade will take hold.

Also, if you are using the vpn-start service, do not use the full file path that is there by default; instead just use the openvpn call like you would in a terminal and use the file path to sudo /usr/bin/sudo before the openvpn call like this:

/usr/bin/sudo openvpn --daemon --script-security 2 --config mykeys.ovpn

If you don't make this change, it will try to run the older version of openVPN and will run into all kinds of issues.

Coral advertises 4 TOPS with tensorflow lite and VOXL 2 should achieve 15 TOPS with tensorflow lite.

Hi @rapit were you able to connect with the docker container at the end?

@tom there is no other methods for example use your nsenter ?!

hello @colerose how do u get all these topics by launching just roslaunch voxl_mpa_to_ros voxl_mpa_to_ros.launch because when i launch it i get just these topics :
MPA to ROS app is now running

Thank u in advance for your reply

4G / LTE is a cellular protocol. The range and performance is determined by the cellular carrier whose service you are paying for. You can use your smartphone as a good proxy for performance.

It would be best if you were comfortable with VPN and networking technologies before you try to build a cellular connected drone. There is know how and work involved.

The Sentinel and VOXL 2 are open development platforms. ModalAI does not use or support Matlab UAV toolbox. So, if you need that feature you will need to figure out how to implement on VOXL 2. VOXL 2 is a Debian Linux system, so it is very flexible

Has someone already solve this?

Hello, @Nicolas-Brissonneau:

I am trying to do the same thing as you and am stuck with the same problem. Did you manage to solve it?

Thanks for the replies.

The use case is low-bandwidth, short range communication to the VOXL using low-energy devices, which only have BLE.

It sounds like QGC is buffering, have you reached out to the QGC team?

The VOXL is a Linux device with standard Linux networking. You should be able to use standard Linux routing techniques to route your IP traffic

We will have to look into this, we don't have any good answer
