LTE Modem "Feather is Disabled"
-
Hi Guys,
I was working on setting up the LTE modem add-on with the VOXL. I configured the modem properly and even connected to our VPN, and used QGC on the VPN server. However, when I rebooted the VOXL and went through the process of connecting the modem usingvoxl-modem --connect_to_network, I wasn't able to connect and got this as output:Configuring GPIO pins Setting defaults: GPIO_PIN_WWAN_WAKEUP_IN = 1 GPIO_PIN_WWAN_POWER_ON_N = 1 GPIO_PIN_WWAN_RESET_N = 1 feather is DISABLED ENABLE WNC feather module feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED WARNING: feather state transtion failed. enable failed, try again 0 retries remaining ENABLE WNC feather module feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED WARNING: feather state transtion failed. enable failed, try again 1 retries remaining ENABLE WNC feather module feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLEDI know people previously have had this issue and the solution was that they improperly answered the
voxl-configure-modemprompts. But I'm almost certain that this isn't the case because I was able to connect with no problems previously with no issues. What seems to be the problem from my view is that the devices/dev/ttyUSB0and/dev/ttyACM0, which are supposedly the serial port and AT command port respectively, do not exist! I'm not sure if this is normal or if they are suppose to generate, but they do not show up whenls -la /devis run:total 4 drwxr-xr-x. 16 root root 5660 Jan 1 1970 . drwxr-xr-x. 29 root root 4096 Jan 1

voxl-modem. Any help on this as soon as possible would be greatly appreciated! -
Hi @scottesicdrone ,
Just to make sure I understand your setup, are you using a v1 modem or v2 modem?
Another question, did you previously run
voxl-configure-modem? If so there will be a service running in the background on boot attempting to connect to the LTE network.You can check the status of this service by running
systemctl status -l voxl-modem -
Thanks for the quick response! We are using a v1 modem.
We ranvoxl-configure-modempreviously so that definitely could be the case. Here is the output forsystemctl status -l voxl-modem:yocto:/# systemctl status -l voxl-modem ● voxl-modem.service - Modem Initialization Loaded: loaded (/etc/systemd/system/voxl-modem.service; enabled; vendor preset: enabled) Active: active (running) since Thu 1970-01-01 00:00:08 UTC; 51 years 3 months ago Process: 2041 ExecStartPre=/bin/sleep 2 (code=exited, status=0/SUCCESS) Main PID: 2824 (voxl-modem-star) CGroup: /system.slice/voxl-modem.service ├─2824 /bin/bash /usr/bin/voxl-modem-start.sh └─2907 /usr/bin/python /usr/bin/voxl-modem --feather_configure Jan 01 00:00:06 apq8096 systemd[1]: Starting Modem Initialization...

-
@scottesicdrone Okay great, if you went through the setup using
voxl-configure-modemthen you shouldn't need to run anything manually. Can I also see what your voxl-modem config file looks like:/etc/modalai/voxl-modem.conf? As a next step I would try rebooting and monitoring the status of the voxl-modem service withwatch systemctl status -l voxl-modem. -
Here is my

@scottesicdrone Okay let's have you go through the steps manually to see if it's a timing issue.
First, disable the voxl-modem service ->
systemctl disable voxl-modemand reboot.Now, run the following:
voxl-modem --feather_configure-> this should bring up/dev/qcqmi0and/dev/ttyUSB0, make sure these exist before proceedingNext, run:
uqmi -P -d /dev/qcqmi0 --set-network-preference ltethen
configband write /dev/ttyUSB0 0x80aLastly, run
voxl-modem --conect_to_network -
I disabled the service and ran
voxl-modem --feather_configureand got this:Configuring GPIO pins Setting defaults: GPIO_PIN_WWAN_WAKEUP_IN = 1 GPIO_PIN_WWAN_POWER_ON_N = 1 GPIO_PIN_WWAN_RESET_N = 1 feather is DISABLED ENABLE WNC feather module feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED WARNING: feather state transtion failed. enable failed, try again 0 retries remaining ENABLE WNC feather module feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED feather is DISABLED WARNING: feather state transtion failed. enable failed, try again 1 retries remaining ENABLE WNC feather module feather is DISABLED feather is DISABLEDAnd this will keep going if I let it, I'm pretty sure. In the
/devfolder,/dev/qcqmi0exists but/dev/ttyUSB0doesn't exist. -
@scottesicdrone Thanks for the info, I will look into this behavior in order to get a solution for you
-
Thanks, Tom, for the help! I really appreciate it! Is it possible that the serial port and the ports got renamed from
/dev/ttyACM0and/dev/ttyUSB0? I'm not too familiar with how these devices are generated or normal behavior for these devices. We have also noticed that this happened on two different VOXLs with the same v1 modem, so this problem seems to be with the modem and not the VOXL (though this is not something I am 100% certain about). -
@scottesicdrone I'm leaning toward it being a hardware issue with your modem. Did anything hardware related change from when it was working and wasn't working? Do you have any other v1 modems you can test with?
-
Nothing physically changed that I can recall, and unfortunately, we don't have extra modems though we ordered more modems. Last potential useful bit of info: when I ran dmesg, I saw errors relating to qmi pop up but I don't know what to make of them:

Can you also run
voxl-versionso I can see what system image / package version you're using. -

Just to show you what a working modem would look like:
/ # voxl-modem --feather_configure Configuring GPIO pins Setting defaults: GPIO_PIN_WWAN_WAKEUP_IN = 1 GPIO_PIN_WWAN_POWER_ON_N = 1 GPIO_PIN_WWAN_RESET_N = 1 feather is DISABLED ENABLE WNC feather module feather is DISABLED feather is DISABLED feather is DISABLED feather is ENABLED, device detected: /dev/ttyUSB0It comes up within a few seconds. Good thought about qmi / dmesg, those errors will go away once the modem is powered up correctly by voxl-modem
-
This makes a lot of sense. I have seen this working before but now it just says feather is DISABLED until it power cycles and repeats. So if I understand correctly, after a few seconds,
/dev/ttyUSB0will be created and then the feather is enabled? Also random question: what is a feather exactly? I haven't heard of this before and I tried to look into it but I'm still confused! -
@scottesicdrone Haha okay so "feather" is a remnant from the days that the VOXL predecessor was a Qualcomm product. The nickname for the project at the time was "Eagle", therefore a "feather" was the nickname for an add-on board for the Eagle. So any reference to "feather" in voxl-modem is just talking about the modem add-on board. An example of one of the VOXL's predecessors is currently powering NASA's "Ingenuity" Drone on Mars (https://mars.nasa.gov/technology/helicopter/).
A little ModalAI lore for you that you won't find on Google
-
Love the Lore and good thing to note! Last last thing, here is the link to an instance of me running
dmesgif that's of any use.
output here
I'm going to keep trying to figure this out because this is a time-sensitive situation but if we will know for sure if it's a hardware issue once we get another modem to test it on. Thanks for the help thus far! Anything else I should try on here? -
@scottesicdrone Thanks! I am going to have another resource take a look at the issue and I will update you with our conclusion. I will message you if anything else is needed.
-
Sounds good, thanks!
