other services like websocket.loop() or timeClient.begin () over GSM #434

Any Help? Thanks! |

The ESP core libraries are only built for using the integrated wifi and sockets built on that. When you're using TinyGSM, the ESP is communicating with the cellular chip using a serial line. A TinyGSMClient (or any other Arduino Client) cannot be used in place of the ESP's internal client's in this case. They're completely different classes. |

Hi! With TinyGSM I was able to make it work with a web socket. Do you know why? It’s that different with socket.io ? Thanks ! |

I'm sorry, I know this is pretty old. TinyGSM works on OSI level 4 (or 5 for a few modules that support SSL). Websockets are a level 7 protocol that works on top of TCP. So if you found a library that creates a WebSocket on top of a standard Arduino client, then it would work with TinyGSM. But functions like the websocket and timeclient that are part of the ESP32 core are NOT built on a standard "Client" object; they use a separate class unique to the ESP32 using its internal wifi connection. Other libraries may use the ESP's own Client type or they may use the standard Arduino Client, it depends on the library. But you cannot supply a TinyGSM Client in place of the ESP32's separate WebClient. |

I am on the same search for a way to create a secure websocket via GSM on the TTGO T-Call. Does anyone has a running sample? The ESP-IDF PPPos sample misses some preconfiguration of the SIM800L and in the Arduino-Libraries there seems to be no way to connect a websocket to a instanciated GSM-client. |

@holajuanfe and @maggusscheppi However, I have not been able to them them interworking, I am not a developer to that depth..., but I was lucky to read that it is possible in principle...would it be possible for you to share some code snippets on this? |

Hi, I have commented out the and for connecting via secure websocket in main.c. kind regards, markus |

Hi @maggusscheppi, I am doing project with same functionality. Unfortunately I can't make WebSocket and SIM800L work together. The link you provided gives this response |

Hi, try again pls.
Kind regards, Markus
in main.c you have to change
#define CONFIG_WEBSOCKET_URI "wss://<secureWebSocketServer>:<Port>"
with your data, e.g. "wss://myPrettyWebSockSever.tw:8888"
Also I have soldered the GPS RX pin on GPIO 2 as far as I remember.

with dropping code in github. So i can tell only this link to my webserver
for the sources.

I have commented out the and for connecting via secure websocket in
main.c. Pls. use your own installation. In case u want to use GPS, pls.
check main/nmea_parser.h: #define NMEA_PARSER_CONFIG_DEFAULT() .rx_pin = 2
tells, on which pin to connect the tx of the GPS device. I did not connect
the rx of the GPS device.
kind regards, markus
Hi @maggusscheppi <https://github.com/maggusscheppi>,

not found on this server. I would be very grateful if you could provide
the code

Hello Everyone, thanks for reading my question.
I am trying to program a TTCall with SIM 800L and the TinyGSM library. It's for a college project. Our server works with socket.io.
From the Wifi.h libraries I have no problem, but with the TinyGSM, when I launch services like websocket.loop () or timeClient.begin (), the system reboots and crashes and I have this error in Terminal.
I have tried using TaskHandle_t to use the two cores of ESP32 but I still can't figure out how to do it.
Can someone give me a hand?
Thank you very much!

Scenario, steps to reproduce
I would like to execute webcocket.loop() and timeClient.begin() and i tried to move it to an other loop or in other task and i have the same bad result.
Expected result
the proper emit of the socket or get the time from internet
Actual result
The system crash and restart.
