Codematic commented 7 years ago

I have serious problems to program OpenTracker. I have tried several source codes (3.1.1, 3.1.2 and 3.1.3) but non of those seems to work properly. Also tried to consider to have correct board support package for each of those source code packages (1.0.3 vs. 1.0.4). But that did not help either. Hope some of you have quick solution to this issue.

The board should be 3G version (HW rev 2.4C). img_6184_small

To make sure, I have used this setup with factory firmware more than 2 months and also same power supply were just fine for couple of hours with factory firmware. img_6185_small

Could there be something I have missed while creating tracker.h? (something to define more?)

Also same SIM card is used before without problems.

Is there something else I could try to modify to sort out this issue?

Btw, should all of those source code packages work with this board?

Here is log of issues with the 3.1.2 package:

Looking at your log I can see the modem is working, but AT command echo has been turned off.

Recent firmware versions perform auto-baudrate using the "ATE1" command string, that should turn command echo back on, see for instance: https://github.com/geolink/opentracker/blob/55f2d320504bc305fd885f1ff1d5d4da5c12f680/OpenTracker/gsm.ino#L381

However, in your log the modem reply is only "OK", without command echo. Please check that your firmware does send the "ATE1" command, because old versions only used "AT".

Codematic commented 7 years ago

Thank you for your prompt reply.

I investigated the gsm.ino files I tried with no luck and none of them put the echo on (ATE1).

After realising this I cloned the latest repository where that is on and found out that "RDY" is replied back to cpu from modem. According to "Quectel_WCDMA_UGxx_AT_Commands_Manual_V1.7.pdf" it is not right (should return OK or ATE1).

This is very strange since I managed to run the OpenTracker with original software without any problems (I even took a log for that and there seems to be ATE1 coming back properly).

With this issue, I even tried an other power source, but this is now something else than power source issue. (In other words: No help from that change.)

Please see the log with the latest code from the up to date repository:

The OpenTracker will loop this constantly..

gsm.ino "gsm_send_at()" looks following now:

int gsm_send_at() {
  debug_print(F("gsm_send_at() started"));

  int ret = 0;
  for (int k=0; k<5; ++k) {
    gsm_port.print("ATE1\r");
    status_delay(50);

    gsm_get_reply(1);
    ret = (strstr(modem_reply, "ATE1") != NULL)
      && (strstr(modem_reply, "OK") != NULL);
    if (ret) break;

    status_delay(1000);
  }
  debug_print(F("gsm_send_at() completed"));
  debug_print(ret);
  return ret;
}

Any more ideas how to solve this issue? Could there be some setting in modem which could be resetted somehow?

Do you have any similar HW rev 2.4C boards available there to test the same? Could this same issue be repeated(?).

Hope you could reply soon. Thank you in advance.

ppescher commented 7 years ago

The RDY message is a kind of "URC" (unsolicited result code) which is sent by the modem to notify about particular events (in this case the modem is ready to accept commands). The problem is that the modem appears to be "ready" (RDY) after all attempts to receive a reply.

Try to #define DEBUG 10 in your Tracker.h That will start a debug terminal after modem initialization (which will fail after 1 minute in your case) and you will be able to manually send AT commands to the modem. Things you can try to type: AT ATI ATE1 Until you see an echo of what you type on the serial monitor, just before the modem reply.

If you can get sensible replies from the modem and enable the echo, then it might be a timing issue. The code does not wait long enough for the modem to become ready and start replying normally. In that case it should be enough to modify gsm_send_at() to retry 10 times for example, instead of 5 (every attempt takes roughly 1 second).

Well, thank you once again for your support. The initial issue were not to define MODEM_UG96 at all in tracker.h. After that, I got it working somehow, but still connecting to server is not working. It seems to be right here.

The key error message is +CEER: "No report available" as shown below.

In gsm.ino it is about this function :

int gsm_connect() {
  int ret = 0;

  debug_print(F("gsm_connect() started"));

  //try to connect multiple times
  for(int i=0;i<CONNECT_RETRY;i++) {
    // connect only when modem is ready
    if (gsm_get_modem_status() == 0) {
      // check if connected from previous attempts
      int ipstat = gsm_get_connection_status();  

      if (ipstat > 1) {
        //close connection, if previous attempts failed
        gsm_port.print(AT_CLOSE);
        gsm_wait_for_reply(MODEM_UG96,0);
        ipstat = 0;
      }
      if (ipstat < 0) {
        //deactivate required
        gsm_port.print(AT_DEACTIVATE);
        gsm_wait_for_reply(MODEM_UG96,0);
        ipstat = 0;

#if MODEM_UG96
        gsm_port.print(AT_ACTIVATE);
        gsm_wait_for_reply(1,0);

        gsm_port.print(AT_CONFIGDNS "\"8.8.8.8\"");
        gsm_port.print("\r");

        gsm_wait_for_reply(1,0);
#endif
      }
      if (ipstat == 0) {
        debug_print(F("Connecting to remote server..."));
        debug_print(i);

        //open socket connection to remote host
        //opening connection
        gsm_port.print(AT_OPEN "\"");
        gsm_port.print(PROTO);
        gsm_port.print("\",\"");
        gsm_port.print(HOSTNAME);
        gsm_port.print("\",");
#if MODEM_M95
        gsm_port.print("\"");

          ipstat = 0;
        else
        do {
          gsm_get_reply(1);

#if MODEM_UG96
          char *tmp = strstr(modem_reply, "+QIOPEN: 0,");
          if(tmp!=NULL) {
            tmp += strlen("+QIOPEN: 0,");
            if (atoi(tmp)==0)
              ipstat = 1;
            else
              ipstat = 0;
            break;
          }

            strstr(modem_reply, "ERROR")!=NULL) {
            ipstat = 0;
            break;
          }
#endif
          addon_delay(100);
        } while (millis() - timer < CONNECT_TIMEOUT);
      }

      if(ipstat == 1) {
        debug_print(F("Connected to remote server: "));
        debug_print(HOSTNAME);

        ret = 1;
        break;
      } else {
        debug_print(F("Can not connect to remote server: "));
        debug_print(HOSTNAME);
        // debug only:
        gsm_port.print("AT+CEER\r");
        gsm_wait_for_reply(1,0);
      }
    }

    addon_delay(2000); // wait 2s before retrying
  }
  debug_print(F("gsm_connect() completed"));
  return ret;
}

Any ideas what to test next?

Btw, with the #define DEBUG 10 the code did not reached the testing phase at all since the MODEM_96 were not defined (it just rebooted earlier).

Thanks.

Ok, you don't have to define MODEM_UG96 manually. It is defined automatically when you select the correct board hardware in the Arduino IDE: in the menu Tools > Board Version you should set "OpenTracker 2.5 (3G)" (the board revision number is a mistake, it's ok for 2.4C and will be corrected in the next release).

Please make sure you have configured the APN correctly for your SIM card. I don't see the initial diagnostic messages in your log.

Finally I got it working.

I added these two lines into the gsm.ino :

Got error stating: +QIGETERROR: 552, invalid parameters

The real pain were these preprocessor IF-statements:

UG96 does not like parenthesis around the port number.

Summary to solve this issue with UG96 modem were just to define those two preprocessor parameters to the tracker.h:

#define MODEM_M95 0
#define MODEM_UG96 1

Just noted Paolo's last reply...

Tested the board definition and yes indeed, it will clear the same.

Hmm, such a small issue (the board number 2.5 vs. 2.4C) but causes many hour of investigation.

Anyway Paolo, thank you for your constant and prompt support. I will close this for now.

ppescher commented 7 years ago

FYI - I've just released board support package v1.0.5 (you can get it via Arduino IDE Board Manager) and firmware package v3.2.0

I know this comes just a bit too late for you and I'm sorry for the inconvenience. Our release policy so far has been to follow our board production schedule, unless immediate action to fix serious bugs is deemed necessary. This time we had some delay due to summer closing. Thanks for understanding.
