Re: [Quectel 5G modem update/firmware for RB5 platform](/topic/2517/quectel-5g-modem-update-firmware-for-rb5-platform)

Hello,

I'm in Germany working with the RB5. We have 7 of them in the lab.
Following the instructions for connecting the drone via modem (https://docs.modalai.com/voxl-modem/), 

1) how to select the APN if none of the option is working
2) how to connect the drone via modem to a 5G router that has a SIM card? 

----------------------------https://docs.modalai.com/voxl-modem/---------------
Which APN is correct for your SIM card?

AT&T - IoT device - APN: m2m.com.attz
AT&T - Laptop or Tablet - APN: broadband
AT&T - Smartphone - APN: phone
T-Mobile - APN: fast.t-mobile.com
Verizon - APN: vzwinternet
Google Fi - APN: h2g2

1) m2m.com.attz	      4) fast.t-mobile.com  7) Custom
2) broadband	      5) vzwinternet
3) phone	      6) googlefi
#?
-------------------------------

Best wishes,

@tahawaru Probably would want to choose `custom` then. What operator are you using? What APN do they specify?

## Reply by tahawaru · 2024-05-10 13:48:45 UTC

@Eric-Katzfey 

I have a SIM card from Deutsche Telekom(https://www.telekom.de/hilfe/mobilfunk/mobiles-internet/mobilfunkstandards/apn-ratgeber?samChecked=true). From the above link and on my phone,one can read:
APN: internet.v6.telekom

I don't know if I will need a username and password after entering these data.
Probably, I should ask them as well.

Best wishes,

I have tried with a telekom SIM card (APN: internet.v6.telekom). I have the following output:

@tahawaru Before using `quectel-CM` can you try running the following to set the network mode to LTE + 5G as a test:

```
echo -ne "AT+QNWPREFCFG=\"mode_pref\",LTE:NR5G\r" | busybox microcom -t 1000 /dev/ttyUSB2

```

And as a note this is how you can experiment with sending AT commands to the modem for debugging purposes

## Reply by tahawaru · 2024-06-05 17:06:48 UTC (in reply to tom)

@tom 
Done!
rb5:~$ echo -ne "AT+QNWPREFCFG=\"mode_pref\",LTE:NR5G\r" | busybox microcom -t 1000 /dev/ttyUSB2
AT+QNWPREFCFG="mode_pref",LTE:NR5G
OK

-------------an then ---------

What is the correct procedure to have the 5G connection up and running?

## Reply by tom (ModalAI staff) · 2024-06-05 17:31:40 UTC (in reply to tahawaru)

@tahawaru You might have to reach out to your telecom company to confirm that they allow connection to their network via. this Quectel modem

## Reply by tahawaru · 2024-06-28 12:35:19 UTC (in reply to tom)

@tom 

I have reached out to the SIM card and APN telecoms provider.
They gave me a username and a password.
Where can I input those 2 parameters?

Best wishes,

@tahawaru `quectel-CM` is not something that we developed, it's a tool from Quectel themselves so I can't give you a definitive answer but looking at `quectel-CM -h` it looks like you can do something like this:

`quectel-CM -s $APN $USERNAME $PASSWORD`

This is the source if you want to see how that flag's arg parsing works: https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-modem/-/blob/master/src/quectel-CM/main.c?ref_type=heads#L665

@tom 

I'm using a mobile prepaid SIM card.
There are other SIMs available such as IoT SIMs.
May be an IoT SIM card will be suitable for this situation.

@tahawaru I like using Google Fi, super easy to setup
