can you try the bare minimum code, without any sensor code. So that we can first check that we can atleast connect.
I did remove all the sensor info byt again could not connect.
Once I commented the Cayenne.begin(username, password, clientID, SerialAT, apn, gprsUser, gprsPass, GSM_PIN); command, the modem begun to try to connect to the internet. Below is the Setup loop containing the comment I commented
void GSM_setup() {
Serial.begin(115200);
Serial1.begin(115200);
// Set console baud rate
SerialMon.begin(115200);
//delay(10);
Serial.println(āCheck 1ā);
// !!!
// Set your reset, enable, power pins here
// !!!
SerialMon.println(āWaitā¦ā);
// Set GSM module baud rate
//TinyGsmAutoBaud(SerialAT,GSM_AUTOBAUD_MIN,GSM_AUTOBAUD_MAX);
SerialAT.begin(9600);
delay(3000);
// Restart takes quite some time
// To skip it, call init() instead of restart()
SerialMon.println(āInitializing modemā¦ā);
modem.init();
// modem.init();
String modemInfo = modem.getModemInfo();
SerialMon.print("Modem Info: ");
SerialMon.println(modemInfo);
#if TINY_GSM_USE_GPRS
// Unlock your SIM card with a PIN if needed
if ( GSM_PIN && modem.getSimStatus() != 3 ) {
modem.simUnlock(GSM_PIN);
}
#endif
//Cayenne.begin(username, password, clientID, SerialAT, apn, gprsUser, gprsPass, GSM_PIN);
}
when i mean the basic example i mean this code, without any modification
/*
This example shows how to connect to Cayenne using a GSM device and send/receive sample data.
The CayenneMQTT Library is required to run this sketch. If you have not already done so you can install it from the Arduino IDE Library Manager.
Steps:
1. Install the TinyGSM library (https://github.com/vshymanskyy/TinyGSM) from the Arduino Library Manager.
2. Set the Cayenne authentication info to match the authentication info from the Dashboard.
3. Uncomment the correct GSM modem type and set the GSM connection info, if needed.
4. Compile and upload the sketch.
5. A temporary widget will be automatically generated in the Cayenne Dashboard. To make the widget permanent click the plus sign on the widget.

I do not get any connections shown in Cayenne dashboard thoiugh
add a new device to dashboard and use the new client id in the code. Also add #define CAYENNE_DEBUG
Ī ĻĪæĪ³ĻĪµĻĻ Ī¼Ī±Ī“Īµ,
By disabling Cayenne.loop(); command, sensor readings returnwed to normal print speed and acuracy.
Any ideas on a solution/workaround?
Dear Shramik,
Adding a new device seems to have solved the issue and the system has succesfully connected to Cayenne.
One issue I am facing is that now I am not getting correct readings from my MPU 6050 accelerometer connected to SCA and SCL pins of a MEGA , when running the sensor script combined with the sensor code part.
Please note that the sensor script works fine when used on its own.
I have also disabled the //#define CAYENNE_DEBUG and
//#define CAYENNE_PRINT Serial comands.
Any ideas anyone?
let gets clear, that the basic code works and connect to cayenne. Can you share serial monitor screenshot with #define CAYENNE_DEBUG
Yes,
Of course, please find below

looks good. I hope you donāt get any frequent network disconnect issue.
So next, step is to read the MPU reading on the mega and show on serial monitor.
Yes.,
I have no issues woith connections. The issues I have is that when the Cayenne.loop() is included the sensor readings are false or do not change even when the sensor is moved?
Any ideas on this?
that is because this is synchronous execution. It check the connection. You can do one thing is just change the time interval using Cayenne.loop(10) or but again when this is called the MPU wont be able to give reading.
This cannot be changed as a behavior although Iam using a MEGA?
At some point I got readings of a small angle change equal to 700!!! The sensor;s behavior is altered complketely
Shramik,
I did set the Cayenne.loop(10) script but unfortunately did not get any change in operation. Any thoughts?
can you share the code and serial monitor output.
i already explained here
There is not other way to deal with this? This makes the sensorās readings unreliable I am afraid.
Would it be possible to store the sensor readings in a variable and transmit this variable to Cayenne each time Cayenne.loop(10) is called?
Would this be a workaround?
