@Barry-Hammond https://docs.modalai.com/voxl-streamer/#how-to-stream-video-with-rtsp-on-voxl Quality greatly depends on your LTE coverage and VPN performance. I recommend lowering the bitrate in /etc/modalai/voxl-streamer.conf until you're happy with the response rate. Tailscale can add overhead as well and our recent LTE testing has involved hosting a custom WireGuard server.

@spiff You'll likely need to reach out to Sierra Wireless directly for debug help.

@Capstone-0 Our drone crashed and we ditched our project but has ModalAI added support for AT commands for the 5G (I assume EM9291) modem yet? If not, I figured out how to do it and posted instructions here https://forum.modalai.com/post/19131 Once you get those commands, you can set up a service to query the modem for its signal strength and pump the output somewhere. Someone else in that forum discusses it a bit.

@Moderator Mint operates on the TMobile network so you we use the APN: fast.t-mobile.com. I have noticed that when I use the Mint SIM in an Android phone it uses the wholesale APN but fast.t-mobile.com will work with our modems.

@Alex-Kushleyev That was it! I first tried with a lower baud rate of 250K on PX4 and I started getting the battery info. Then as you recommended, I uploaded new parameters to the ESC. I used: python3 voxl-esc-upload-params.py --params-file ../voxl-esc-params/D0014_starling_1504_3000kv_ms_props/D0014_starling_1504_3000kv_ms_props.xml because I will be using it on a drone of similar size and performance. Then with 2M baud rate in PX4, I was able to make it work! Thank you.

@LR The 5G configuration on Starling 2 is a fairly new offering so there may not be fully representative docs live.

Hi @dan64 That is not the standalone Modem board variant and many other components are missing to make this work. We do not currently sell the "standalone" version of the M0090 (5G) or M0130 (4G LTE), so sadly your efforts will hit a dead end.

@Thomas-Eiszler That's the plan we're working towards also, I did make some tries with AT commands also, but had to put the work aside for other commitments in the past few weeks. The information from yourself and @groupo above helps a lot. It shouldn't be too hard to make a service out of a python script for this. I'd been pursuing getting the data direct from the Qualcomm chipset, but AT commands and gpsd queries seen to be the way to go.

OK, cool thanks Will try.

@David-Smyth Would you be willing to share the .service files you created?

@pthomason Anyone have thoughts on correcting IP bindings, or the list of services that need to be restarted to notice a new 5G connection?

@tom That's really excellent news that you are working on the AT Command issue. I'm really looking forward to the update. The thermal pad seems to be self-adhesive. When you loosen the screw it is held in place by the thermal pad. I suspect that the thermal pad will need to be replaced if you force it off. Do you have a type designation for the thermal pad? Then I can buy a replacement somewhere. Quectel modems are updated by plugging them into a USB adapter, connecting it to a Windows PC and installing the firmware update using proprietary Quectel software. With Sierra it probably works in a similar way.

@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

@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.
