No gsm ESP32

[Skons]

Is it possible to flash an esp32 that does not have a GSM module?

No, isn't possible, because the GSM module is required to send data to the Broker.

First off, amazing project thank you!

Same question, I have a home assistant running in my camper van, I want to use this locally so no sim card needed. I Just want to connect the ESP to vans wifi and send data directly to the broker running in the van. I loaded it up on a non-cellular module, the only option missing is the ability to connect to a network, otherwise i think it will work.

There are a few technical reasons for this. An ESP32 shares one antenna for BT and WiFi, which means it can only modulate/demodulate one wireless protocol at a time.
In Espressif, RF coexistence is supported, but this is a bit unstable if you use classic BT.
