Let me know if you have any specific changes that would be applied to the mentioned file, I've just tried changing the mavlink start parameters to these below:

mavlink start -u 14556 -t <my device IP>

I've removed -m and -n for each tests I was running, initially it was ending with the -n lo -m custom from the sample line.

Hi @modaltb ,

Pings are working between the device and drone.
From desktop to drone it isn't so a firewall might be blocking, but anyway, the desktop should not be an issue as I won't be using it, my focus is to have it working through the cellphone application.

I've tried changing the config file but keep having the same message there.
I'll change the devices here and give it another try.

I've been trying to check the drone configuration and services but again I'm getting an error, below:

Vehicle 1 did not respond to request for parameters. This will cause QGroundControl to be unable to display its full user interface.

The QGroundControl (Mobile - iPhone) Version: is v4.0.1.0 (The mentioned error message appears for mobile only)
QGroundControl (Windows Desktop) - Version: Development HEAD:f9ebc2720 2021-08-31 06:55:11 +0000 (Although no error message is shown, it won't connect anyway)
I've tried Wifi networks uusing both 2.4GHz and 5GHz.

From the link https://docs.modalai.com/Qualcomm-Flight-RB5-sdk-services/#how-to-configure
I could not see if there is any further configuration to be done to have it working.

Let me know.

@tom said in Can I control the drone through 5G (No Spektrum Transmitter) ?:

/etc/systemd/system/rb5-net-check.service

Thank you @tom ! It worked!

I've set up a new network with very few restrictions and now it is connected to the network! Thank you very much for your support!

Hi Chad,

Thanks for the directions.

I was going through the initial setup and I'm stuck at the point to connect to QGroundControl.
I'm at the same NW as the drone but when I check the status for the P4X it shows the following:

sh-4.4# systemctl status rb5-px4-start
● rb5-px4-start.service - rb5-px4-start
   Loaded: loaded (/etc/systemd/system/rb5-px4-start.service; enabled; vendor pr
   **Active: inactive (dead)**
lines 1-3/3 (END)

I've tried disabling/enabling and rebooting but I still could not see the drone on the QGC app..

Wifi is now up and running:

sh-4.4# ifconfig wlan0
wlan0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 10.188.113.109  netmask 255.255.255.0  broadcast 10.188.113.255

Let me know if any further configuration is necessary to have it available to connect on QGC.

@tom I've tried two different networks so far, one from my company so a firewall might be affecting the connection attempt through WPA, other using my iPhone Hotspot which is WPA2 so I'm unsure whether this might be an issue. I'm setting up a new one with no restrictions (no firewall, no wpa2).

I'll update here accordingly.
Thanks

@tom Yep, after any change on the file I'm rebooting.

@modaltb It's the pretty same as I have here. I've tried keeping the pairwise and group for some attempts but also didn't work.

I've been trying to connect to different wifi networks and I'm unable to succeed on that.
WPA supplicant file is being updated as below:

ctrl_interface=/var/run/wpa_supplicant
update_config=1

network={
#WPA-PSK
        ssid="Test1"
        key_mgmt=WPA-PSK
        psk="abcdefgh"
}

And I just can't see any error but the connection is not established. Test1 is a hotspot on my cellphone, should I use WPA2-PSK instead?

Hotspot settings are as follows:

SSID:	Test1
Protocol:	Wi-Fi 4 (802.11n)
Security type:	WPA2-Personal
Network band:	2.4 GHz
Network channel:	1

Thanks

Or the 5G is only for viewing the camera?
