Hello @JeroenKl,
I can’t found the at command AT+QICSGP to configure APN
For example: Using hologram sim card
For example: Using hologram sim card
“apn_name”, username, password
Set the APN to “hologram” with no username or password.
AT+QICSGP=1,1,"hologram","","",1
Then Activate the PDP context.
AT+QIACT=1
If ok you then you can establish the TCP connection and send AT+QPING
Hi @marcio,
It looks like ‘Hologram’ isn’t the correct way in order to set the APN for KPN provider in the Netherlands. I made progress with:
AT+CGDCONT=1,“IP”,“kpnthings.iot” and AT+CGACT=1,1
Now I’m getting an IP address but still not able to ping the WAN network:

Why can I not ping to WAN (yet)?

Hi @JeroenKl,
Can you try “internet” as the APN? Where did you find “kpnthings.iot” as the APN for KPN?
This APN is provided by KPN together with 2 test LTE-M sims I received.
I see. It seems if you will use their standard cellular connection (2G, 3G, LTE), you can use “internet” but you got an IoT sim for LTE-M that’s why you need to use kpnthings.iot. That’s how I understand it, I might be wrong.
Also, on your screenshot, you have multiple RDY replies from module. That can be an indicator that the module doesn’t not have a good power source.
Hello @JeroenKl,
Hologram is global sim card.
(Hologram
KPNThings has another APN.
Have you tested kpn sim card on cell phone?
For hologram sim card you need to activate it before using.
I do not have Hologram SIM, but I have KPN LTE-M Sims with KPN APN which I need to use according KPN.
It is activated, I get a connection and IP address but cannot ping (error message)
You are right, this is the case
I’m using the Cellular_ping INO which requires a terminal connection. So the device is hooked up to my laptop.
I can change the setting so the device will run without a serial connection but then I cannot see if the ping is working.
I think it is time to provide a ‘example, solution’ script (INO)
Hi @carlrowan,
Could you please check if the LTE-M (CAT-M1) functionality is tested thoroughly and confirmed it should work according specs?
BR,
Jeroen
Hi @JeroenKl,
Marcio already tested it on his hologram sim and it works. Quectel forum is a good reference as well if a user from Netherlands successfully used KPN LTE-M1 connection using BG77.
Hi @carlrowan,
Thanks, of course I will not rest to have the KPN fixed so I’ll investigate further and keep you updated.
Any topic on Quectel forum you can pinpoint me regarding KPN LTE-M1?
Br,
Jeroen
@JeroenKl
The error message does not help much. You can add AT+CMEE=2 command to get more error details.
I also used the command AT+CFUN=1,0 before activate the PDP context.
Hi @marcio ,
I’m sorry to inform but it didn’t help.
I’ll ask KPN forum for assistance to check if something is wrong on their site, because I do have a good connection, good level and an IP address.

Hello @JeroenKl,
Check your Quectel revision using ATI command.
Mine is Revision: BG77LAR02A02.
Another attempt is to try to open TCP connection AT+QIOPEN even if the ping does not work.

Hello @JeroenKl
If you look closely, your ping has an slanted quotation mark; The correct ping must have a vertical quotation mark.
I think you should replace all the slanted quotation mark on AT commands.

Hello @JeroenKl,
Good news 
There is no error number 561 on documentation.
Initial part of the ping reply was lost.
