Hi from tomorrow evening I have such problem. On this hardware Blynk works and connects fine. What can be wrong?
[1012] Initializing modem
[1023] Waiting for network
[1027] Connecting to GPRS
[8114] Connected to GPRS
[8119] IP: 10.72.72.102
[8119] Connecting to mqtt.mydevices.com:1883
[39984] MQTT connect failed, error -1
can you try adding a new device to your cayenne dashboard and use the new MQTT client id in the code.
same problem with new device
which device are you using? and can you share the code you are using?

/*
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.

Maple Mini - DEV-11280 - SparkFun Electronics is it this product?
yes
does it contain GSM?
No damn it’s waiting for when Elon Musk make a free satelite ineternet over the world… Can you stop to ask stupid question with obvious
answers ??.. Device is workable, it still work with Blynk but in Cayenne I get this errors over two past days
Maybe ask Elon Musk only then if you cannot answer to the question i ask. As, in the link i shared above there is mention of GSM (maybe i missing something). it is just an 32-bit ARM development board.
But in code (if you actualy read ) you can see:
// Uncomment your modem type:
#define TINY_GSM_MODEM_SIM800
// #define TINY_GSM_MODEM_SIM808
// #define TINY_GSM_MODEM_SIM900
// #define TINY_GSM_MODEM_UBLOX
// #define TINY_GSM_MODEM_BG96
// #define TINY_GSM_MODEM_A6
// #define TINY_GSM_MODEM_A7
// #define TINY_GSM_MODEM_M590
// #define TINY_GSM_MODEM_ESP8266
// #define TINY_GSM_MODEM_XBEE
Upload this code TinyGSM/MqttClient.ino at master · vshymanskyy/TinyGSM · GitHub and see if you get connected to MQTT broker.
What does “MQTT connect failed, error -1” realy means? I can’t find any error code descriptions.
here you can find MQTT Client and Broker and MQTT Server and Connection Establishment Explained - MQTT Essentials: Part 3
So if “1 Connection refused, unacceptable protocol version” may be you updated protocol couple days ago?
there were no recent update. Did the tiny gsm code worked?
I will try soon
Why you gave me a third-party connected sketch const “char* broker = “broker.hivemq.com”;” now I need to register at that sevice too?
that is because cayenne GSM code and wanted to confirm whether it is not an issue with the library itself or the device.
