Hello,
I've bought a MKR 1400 GSM and an Arduino SIM card that I have activated 8 days ago.
I've plugged an ultra wide band antenna (Taoglas FXUB63) and a 3.7V 1800mAh battery, a USB power from a PC and even a 5V lab power supply (5A max) between the VIN and the GND of the board.
But I can't succed in connecting to the Arduino IoT Cloud. I'm trying too with the Arduino example sketch TestGPRS, and here is what I see on the serial monitor:
14:58:44.361 -> Connecting GSM network...OK
14:58:56.682 -> Enter your APN: prepay.pelion
14:58:59.921 -> Now, enter your login: arduino
14:59:02.700 -> Finally, enter your password: Attaching to GPRS with your APN...
14:59:32.510 -> ERROR
14:59:32.510 -> Connecting GSM network...OK
14:59:46.231 -> Enter your APN: prepay.pelion
14:59:59.614 -> Now, enter your login: arduino
15:00:02.343 -> Finally, enter your password: Attaching to GPRS with your APN...
15:00:10.368 -> ERROR
(the password I put when asked is arduino, as recommended here
I've tried with the SIM card of my personal phone, and it works (I mean I can connect to the Arduino IoT Cloud and use the dashboard, etc.), that's why I guess it's an issue with the Arduino SIM card.
If it can help, I'm based in Paris, France...
In order to perform more tests I've running the Arduino example sketch called TestGPRS. With the Arduino SIM the result on the serial monitor is:
17:49:27.754 -> Connecting GSM network...OK
17:49:39.296 -> Enter your APN: prepay.pelion
17:49:41.598 -> Now, enter your login: arduino
17:49:46.143 -> Finally, enter your password: Attaching to GPRS with your APN...
17:49:52.986 -> ERROR
17:49:52.986 -> Connecting GSM network...OK
And with my personnal SIM it's seems to work better:
17:51:25.736 -> Connecting GSM network...OK
17:51:38.482 -> Enter your APN: mmsbouygtel.com
17:51:55.465 -> Now, enter your login:
17:51:56.965 -> Finally, enter your password: Attaching to GPRS with your APN...
17:52:04.850 -> OK
17:52:04.850 -> If your carrier uses a proxy, enter it, if not press enter:
17:52:08.271 -> Connecting and sending GET request to example.org...OK
17:52:11.792 -> Receiving response...
17:52:12.969 -> disconnecting.
17:52:12.969 -> Connecting GSM network...OK
I can paste the TestGPRS code if needed, but it's juste the one given in the Arduino IDE, I've just modified the PIN number of course.
Has anyone an idea of what can be the problem ?
Thanks in advance for your help !
Best regards,
Antoine
