Error 601 on HTTP_GET/HTTP_POST

[davilox]

Hi, I´m experiencing the 601 error (Network error) on HTTP requests.

I'm using a FONA SIM808 V2 (R14.18) with an spanish Orange 4G SIM.

The SIM is without PIN and is set to run only on GSM network (not WCDMA).

If I use the SIM with a Samsung Galaxy Tab 8 (only GSM/WCDMA) and its able to browse any web via GPRS, why when I use it in the FONA SIM808 get this error?

Operator assures me he keep a 2G network and that the SIM is not choosing the network used, is always the device.

Thanks in advance.

What code are you running?

I also recently started to see 601's - driving a FONA 808 (w/gps) with a Feather M0 with BLE. It generally runs fine, but today I started to see it coming back with 601's. I cut and paste the exact same URL/Data from the serial monitor into Chrome and it posts correctly. I rebooted the Feather/FONA and all was well again. Is there an HTTP Reset function available? I realize that things can sometimes go into an undefined state and start failing. As long as I can restart the session or whatever, I'm happy, but I don't see anything. Here's the command that normally works just fine.....

if (!fona.HTTP_POST_start(dataBuffer, F("text/plain"), (uint8_t *) data, strlen(data), &statuscode, (uint16_t *)&dlength))

The HTTP standard doesn't have a 601 error code, so it's probably something generated by the cellular network. At a guess, it means there was some kind of problem with the basic network connection.

I resolved this by turning GPRS off and then on after an error. That seemed to clear up the 601. However..... and I will be posting separately, there is another problem. The FONA sends an UNSOLICITED notification message when an SMS is received. If that comes while a GPRS function is taking place it causes an error because the library code is waiting for an "Ok" response and instead gets a "CMTI:" response as below. I don't see a way to disable these unsolicited notifications so I'm going to look at changing the library code to ignore them as they serve no useful purpose.
