1.Can you send the prints of the 4) and 5) steps?
2.Can you send the contents of file “/etc/ppp/peers/gprs”？

donald28 · March 18, 2019, 8:26pm

hello, it work fine when a disconnet the wifi and reboot. thank for your help I really appreciate

sri · April 27, 2019, 6:05pm

@Fomi

I’m stuck here. Any help would be very helpful.
I’m not even able to give AT commands, the window is stuck after
“minicom -D /dev/ttyAMA0 -b 115200”
command.

Fomi · April 28, 2019, 1:22am

Hi, @sri

I think maybe you can use the latest firmware for RAK7243 with LTE:
https://www.rakwireless.com/en/download/LoRa/Pilot-Gateway-Pro-RAK7243#Firmware
Please download the one named “RAK7243_LTE_…” .

In the latest firmware, we’ve added a configuration UI, so you can configure it easily now.

sri · April 28, 2019, 6:06am

Thanks @Fomi now I can see all the 3 LEDs light up but connect script failed error.

The Cellular Module doesn’t connect to the internet. Any thoughts?

Fomi · April 28, 2019, 9:47am

Hi, @sri

Can you execute the following command?
sudo minicom -D /dev/ttyAMA0 -b 115200
and type:
ATI

Then give me the log picture.
Thank you!

sri · April 28, 2019, 10:27am

@Fomi

Please find the result.

51%20PM

Hardly the cmd prompt is interactive if I enter the minicom cmd.

Thank you.

Revision info came after I hit another key stroke:

Quectel
BG96
Revision: BG96MAR02A07M1G

When I hit “sudo pppd call gprs”

It fails like this:

Fomi · April 28, 2019, 10:58am

Hi, @sri

You can type “at+cops=?” to get a network operator information, for example, i can get the following information in China:
2,“CHN-CT”,“CT”,“46011”,7

I think you can get some information like this too.
If it is, please type “at+cops=1,0,xxx,yyy” to set your network operator. “xxx” is the one you get in the last step, like “CHN-CT”, and “yyy” is the one like “7” according to my example.

When you complete these step correctly, you can set APN name on the UI, then restart the device.

Please try again.

sri · April 28, 2019, 11:03am

Hi, @Fomi
This is the error I get.

Fomi · April 28, 2019, 11:08am

Can you try to use another Network operator? For example, IDEA.

sri · April 28, 2019, 11:09am

Sure, let me insert the SIM and let you know. Even if LTE is not connecting it should latch on to EGSM on 900 band.

sri · April 28, 2019, 11:40am

@Fomi I got OK with Idea, but no connectivity.

Executed “sudo pppd call gprs” and I get OK OK and fail this time too.

The Gateway is going up when on WiFi but on cellular ‘No’.

ZhuQI · April 29, 2019, 1:39am

Yesterday you have used the at command to configure IDEA successfully.
Can you try the following steps?
1.reboot gateway
2.Use “sudo gateway-config”,choose “Configure LTE module”, choose “Disable LTE…”
3.Choose “Configure LTE module”, choose “Active LTE module”
4.Use “sudo gateway-config”,choose “Configure APN name”,reset the APN name “IDEA”
5.reboot gateway
6.Use “sudo gateway-config”,Choose “Configure LTE module”, choose “Active LTE module”
7.Use “sudo pppd call gprs”,Can it be successful?

sri · April 29, 2019, 4:36am

@ZhuQI thanks for your reply ZhuQI,

Yes, I have been trying since 3 days various steps, in-fact the above steps as well, but they yielded no result.

Do you know anyone from India who was able to successfully use gprs? any help is appreciated.
Thank you much.
Sri

I’m reaching CGREG Ok, but when trying to Connect:

send (AT+CGDCONT=1,"IP","gprs.movistar.com.ar",,0,0^M)
expect (OK)

Does anyone have an idea of what may be happening?

Thanks in advance

ZhuQI · May 27, 2019, 3:39am

I am sorry to see your post so late.
Can you post the print of “at+cops=?”？
