Just added WiFiConnectionHandler to code that previously used WiFi101 for MKR1000 board but now the WiFiOTA does not register the board in the ports selection. If I remove ConnectionHandler and revert back to WiFI101 natively (I know ConnectionHandler just calls this library after testing for ARCH of hardware) it works normally. This does not make any sense, any help would be greatly appreciated.

#include <Arduino_WiFiConnectionHandler.h>
#include <WiFi101OTA.h>

const char* ssid = "_SSID_";
const char* password = "_PASSWORD_";

WiFiConnectionHandler net(ssid, password);

void onNetworkConnect(void *_arg) {Serial.println(">>>> CONNECTED to network");}
void onNetworkDisconnect(void *_arg) {Serial.println(">>>> DISCONNECTED from network");}

void setup() 
{
  delay(5000);
  Serial.begin(115200);
  setDebugMessageLevel(2);
  net.addConnectCallback(onNetworkConnect);
  net.addDisconnectCallback(onNetworkDisconnect);
  WiFiOTA.begin("_HostName_", "_Password_", InternalStorage);
}

void loop() 
{
  net.update();
  WiFiOTA.poll();
}

Helpful library -thanks! Would you consider adding a SSL selector in the calls?

Hello!

Is there any equivalent statement for the MKR ETH shield for the MKR1000 WiFi mode:

WiFiConnectionHandler ArduinoIoTPreferredConnection(SSID, PASS);

Need to use MKR1000 with already tested MKR ETH shield. Thanks.

Kind regards.

Hi @per1234 👋 Can you add CI build for Portenta H7 (M4/M7) - that would be nice to have having merged #37 .

0.7.7. working great on Opta HW using Arduino IDE - and now I want to move the sketch into the PLC IDE tool.

I'm now trying to use the Arduino PLC IDE (ver 1.0.3.1) and it only pulls libraries down from the Arduino Library Manager (i.e. they must be registered and catalogued there). BUT - it isn't working for me. Not sure if it's my tools fault or what. Arduino_ConnectionHandler only shows up on there to version 0.7.6. When I add it to the Sketch/Library manager in the PLC IDE it tries to pull it down (vs 0.7.6 or less) it fails.

Do you have any insight as to why? or where the error may be? I am also pinging the Arduino support to see if the PLC IDE library manager is working.

Hello, not sure if this is issue or just I am newbie and do not know how to correctly call the function :)

I am using this connection handler for GSM MKR connection to cellular network. In my routines I would like to check what is current status of the network and use it for if condition i.e. do not execute condition in main loop until modem is connected.

    if ( (millis()-s2) > 50000 && CONNECTIONREADY) {
       s2 = millis();

       Serial.println("Fifty SECONDS");
    }

However, firstly I tried to insert boolean into routine (CONNECTED) but this boolean gets reseted once get out from the routine and in main loop value is always 0 and do not know why. Can you help to understand why is that ? :)

void onNetworkConnect(void *_arg) {
  Serial.println(">>>> CONNECTED to network");
  bool CONNECTIONREADY = true;
}

Is there better way to set CONNECTIONREADY to 1 or use function which is mention on the readme getStatus(). It says it returns the status, which variable I can read this value from ? Why I can not just read this information without using getStatus() ? How to add it to my if routine to validate condition in main loop ?

Please help me with this,
Thanks,

I have been having trouble with the Arduino MKR GSM dropping the connection to the Arduino IoT cloud and not being able to recover.

I was thinking that it must be the connection to the antenna, so I tried putting dielectric grease on the connection of the antenna. That seemed to help, but I still have had a few times the connection has dropped and failed to reconnect.

I am thinking it is similar to this issue: arduino-libraries/MKRGSM#66.

I think it might be fixed by adding

static int const GPRS_TIMEOUT = 30000;

to the constants in src\Arduino_GSMConnectionHandler.cpp, and then

_gprs.setTimeout(GPRS_TIMEOUT);

directly under

_gsm.setTimeout(GSM_TIMEOUT);

In the implementation of GSMConnectionHandler::update_handleInit() in the same file as mentioned before.

This is what I am planning to try anyways.

I am not that experienced with regards to GSM communication, so if someone has a better idea to try and fix the problem I've been having I'd like to hear it.

is there a possibility that we have an ethernet connection handler? I am working on a project that uses teensy4 and Wiz850 Ethernet module

At line 101 in Arduino_WiFiConnectionHandler.cpp:

The code should check for an empty password and, if so, call WiFi.begin(_ssid) instead of WiFi.begin(_ssid, _password).

WiFi.begin(_ssid, "") results in a failed connection on open networks that do not require a password to connect. WiFi.begin(_ssid) connects successfully.

Hi 👋🏻

I have been struggling some time to connect my Arduino MKR1010 to the Arduino IoT Cloud by my university wifi network, which asks a username and password (WPA2 WiFi network).

For Arduino MKR1010, Arduino_ConnectionHandler establish a connection by creating a WiFi object from WiFiNINA and calling the method .begin(). This method only allows connections with WPA networks (SSID & Password).

If the method .beginEnterprise() from WiFiNINA was included in the class WiFiConnectionHandler fromArduino_WiFiConnectionHandler.cpp, it would be possible to connect to WPA2 Enterprise networks such as eduroam. Again, it only works for devices using WiFiNINA instead of WiFi101. I don’t know if there exists a similar method for the latter.

Lastly, I tried it myself and it works. It only took me minutes to update the code. And it doesn’t change what is made already.

Thanks for the nice library you created!

I am using this along with the arduino mqtt library and its all working well however i now need to connect to an mqtt broker using TLS, i was surprised to find that i cannot use this connection handler library for that, are there are plans to add support this functionality ?

I am attempting to complete the Arduino IoT Cloud's "Get Started" project (https://create.arduino.cc/iot/onboarding) with a MKR1000 and am receiving the following after it asks for Wi-Fi network credentials and attempts to compile the onboarding sketch. I assume there is some issue with this library, because I have yet to type anything and it cannot compile the base sketch.

Hi,
I have a MKRGSM1400 board. When connecting to cloud I have the following messages in serial monitor:

20:35:20.787 -> SIM card ok
20:35:24.801 -> GPRS.attachGPRS(): 4
20:35:24.801 -> Sending PING to outer space...
20:35:29.814 -> GPRS.ping(): -2
20:35:29.814 -> PING failed
20:35:29.814 -> Retrying in  "500" milliseconds
20:35:30.131 -> GPRS.attachGPRS(): 0
20:35:30.131 -> GPRS attach failed
20:35:30.131 -> Make sure the antenna is connected and reset your board.

Then the board stop connecting and I have to reset.

Looking at Arduino_GSMConnectionHandler.cpp, but I am not an expert, I see the following code:

NetworkConnectionState GSMConnectionHandler::update_handleConnecting()
{
  GSM3_NetworkStatus_t const network_status = _gprs.attachGPRS(_apn, _login, _pass, true);
  Debug.print(DBG_DEBUG, "GPRS.attachGPRS(): %d", network_status);
  if (network_status == GSM3_NetworkStatus_t::ERROR)
  {
    Debug.print(DBG_ERROR, "GPRS attach failed");
    Debug.print(DBG_ERROR, "Make sure the antenna is connected and reset your board.");
    return NetworkConnectionState::ERROR;
  }
  Debug.print(DBG_INFO, "Sending PING to outer space...");
  int const ping_result = _gprs.ping("time.arduino.cc");
  Debug.print(DBG_INFO, "GPRS.ping(): %d", ping_result);
  if (ping_result < 0)
  {
    Debug.print(DBG_ERROR, "PING failed");
    Debug.print(DBG_INFO, "Retrying in  \"%d\" milliseconds", CHECK_INTERVAL_TABLE[static_cast<unsigned int>(NetworkConnectionState::CONNECTING)]);
    return NetworkConnectionState::CONNECTING;
  }
  else
  {
    Debug.print(DBG_INFO, "Connected to GPRS Network");
    return NetworkConnectionState::CONNECTED;
  }
}

The first time GPRS.attachGPRS() run successfully but the ping end with -2 so the program try to reconnect again.
The second time GPRS.attachGPRS() run with error, maybe because the GPRS is already connected?

I see in my test that the first ping always end with -2, but putting the ping inside a loop the second or third ping end successfully. I don't know why the first ping is always -2.

So what is the problem? The ping should be put inside a loop or the problem is the attachGPRS?

Please help.

Thanks.

I am using Connection Handler to get connected to GSM network via MKR GSM 1400. From time to time when I restart or reupload the sketch and I am getting error "SIM not present or wrong PIN" attaching screenshot.

When I restart the unit (reset button) or re-upload the sketch connection is successful. Looks to me that function just finish and never continue "void GSMConnectionHandler::init()" Arduino_GSMConnectionHandler.cpp

1. Does this means in default settings there is no 2nd, 3rd etc. retry ?
2. If so, is there any settings to set it up the way to retry again before fail or reset modem etc.?

Thanks a lot
