Can the library be used with pubsub or another mqtt client ?

[cresusjpt]

Hello, great job for this library, it's the only one i play with which answer easily my basic needs: handle incoming call (get phone number), handle incoming sms (getting senderNo and message) and make https post.

But i want to add an mqtt features to my project and can't find a way to achieve it only with this library.

I use it with TinyGSM and Pubsub but since then i'm facing accidental complexity. I no longer systematically enter Serial1.available() in the loop() to process incoming calls or received messages. Sometimes TinyGSM handles it. For example, instead of +CLCC, I get RING or nothing. Other times, nothing happens.

The same goes for SMS. I think it's because i initialise both on the same rx and tx pinout

So does someone achieve to use gsmsim with an mqtt client please ? or perhaps ways to do it ?

Or rewrite if (Serial1.available()) part another way to manage this ?
Im using the lilygo tcall (sim800l and esp32 board)

Not really.
You can only use this library to establish a GPRS connection. After that, you would have to manually communicate with the module to create a TCP connection with the MQTT server, then get PubSub to input/output to the Serial interface where the module is connected.
