## DanielHviid · 2023-04-28 09:40:46 UTC

I'm trying to include a 5G Modem Add-on board on a voxl2, but I cannot interact with it. When I try to control it with voxl-modem, I consistently get an error stating that it cannot ready GPIOs. I can run feather_configure, but detect_modem, read_id and cycle_power all give me the same error. Likewise I can run feather_enable with no issue for usb0-3, but feather_disable fails to disable anything, stating that it's still enabled until it gives up.

I have tried with two 5G modem modules without luck, am I missing anything or could there be some kind of issue with the Voxl2?

@DanielHviid The `voxl-modem` python script itself is not used for the 5G modem at all, nor is it meant to be run manually from the command line.

The modem should enumerate on boot regardless of any other voxl-modem processes running, check this with `ifconfig wwan0`

I recommend running `voxl-configure-modem` and selecting `quectel` from the options. It will then ask if you're connecting to ModalLink, choose `no`. Lastly it'll ask for the APN of your SIM card, choose from the list or enter a custom one.

Once this is complete, the `voxl-modem` systemd service will startup and attempt to connect to your 5G network, the status of this service can be monitored with `systemctl status voxl-modem`

I did a fresh system install to ensure there wasn't any lingering issues, but I still get the following error:

```

Can you share a picture of your setup? Is the Quectel RM502Q-AE installed?

## Reply by DanielHviid · 2023-05-03 06:50:35 UTC

I have tried two separate 5G modules, same issue.

## Reply by tom (ModalAI staff) · 2023-05-03 16:57:02 UTC

@DanielHviid Ensure that both black board to board connectors (left side in pic) are fully seated, the board looks a little crooked. Also double check that the Quectel module itself is fully seated in the pci slot.

What software version are you running on your voxl2? You can check this with: `voxl-version`

## Reply by DanielHviid · 2023-05-04 07:13:11 UTC

The board is fully connected and the voxl2 can find 4 USB connections through it. It looks crooked from the perspective of the image, but is completely parallel with the voxl2 and does not wiggle when pressed. The Quectel module is also tightly connected to the board with the screw that it came with, and I have neither loosened it nor removed it since we received it, with both 5g modem boards we have tested.

We are running this on a clean install of the VOXL2 Platform 0.9 image.

@DanielHviid That all looks as expected, what about if you run the quectel connection manager program manually: `quectel-CM -s $APN` where $APN is your SIM card's APN

@DanielHviid Can you try installing a newer version of voxl-modem?: http://voxl-packages.modalai.com/dists/qrb5165/staging/binary-arm64/voxl-modem_1.0.3_arm64.deb

```
adb push voxl-modem_1.0.3_arm64.deb .
adb shell
dpkg -i voxl-modem_1.0.3_arm64.deb 
```

This new package includes a newer quectel-CM source

@tom Definite improvement, but it seems to be stuck in initialization. This is the output of manually running it it.

@DanielHviid I haven't seen this before with SIM status: `requestGetSIMStatus SIMStatus: SIM_PIN`, I'm wondering if the SIM card is locked and is expecting a pin number? `quectel-CM` allows you to pass in a pincode with `-p`:

```
voxl2:/$ quectel-CM -h
Quectel_QConnectManager_Linux_V1.6.0.24
Usage: quectel-CM [options]
-s [apn [user password auth]]          Set apn/user/password/auth get from your network provider. auth: 1~pap, 2~chap
 -p pincode                             Verify sim card pin if sim card is locked
-p [quectel-][qmi|mbim]-proxy          Request to use proxy
-f logfilename                         Save log message of this program to file
-u usbmonlog filename                  Save usbmon log to file
-i interface                           Specify which network interface to setup data call when multi-modems exits
-4                                     Setup IPv4 data call (default)
-6                                     Setup IPv6 data call
 -n pdn                                 Specify which pdn to setup data call (default 1 for QMI, 0 for MBIM)
-k pdn                                 Specify which pdn to hangup data call (by send SIGINT to 'quectel-CM -n pdn')
-m iface-idx                           Bind QMI data call to wwan0_<iface idx> when QMAP used. E.g '-n 7 -m 1' bind pdn-7 data call to wwan0_1
-b                                     Enable network interface bridge function (default 0)
-v                                     Verbose log mode, for debug purpose.
[Examples]
Example 1: quectel-CM 
Example 2: quectel-CM -s 3gnet 
Example 3: quectel-CM -s 3gnet carl 1234 1 -p 1234 -f gobinet_log.txt

@tom Curriously, it does not seem to accept -p 0000, which was our pin. We changed it to 1234, which is accepted, but that didn't help with the issue, and it acted identically to providing the wrong pin.
