How point out problem by at commands? #26

Closed makotaka closed 6 years ago

makotaka commented 6 years ago

I am testing "SIM7XXX_LTEDemo", but unfortunately, In my environment, "[2] Post to dweet.io via LTE CAT-M / NB-IoT (SIM70000)_" returns error code 601. It seems network error, so I used AT commands to find out the reason, but I couldn't find out yet. It seems on roaming network, but IP function couldn't work. What I should try next ?

Hi, most likely you didn't use the"G" command first.

makotaka commented 6 years ago

All GPRS/2G/2.5G were finished and there only WCDMA/LTE including CatM1/NB-IoT here in Japan... I think the "G" is meaningless, Isn't it?

botletics commented 6 years ago

No, if you run it you will also see that it's not just enabling GPRS but setting the APN and bearer config. Check out the demo wiki which shows the 2G version and a slightly simplified version for the SIM7000 without the unnecessary GPRS commands.

Thanks, I could do it.

Hi, I do try G comand first, so it enables data correctly, but then, it's not able to do neither the GET nor the POST. Any idea which the problem could be?

When you go to dweet.io/get/latest/dweet/for/865234030907363 after you try to do a GET or POST, does the data show up?
