ESP32 board core version

[fbritop]

Hi
I'm trying to setup an MQTT broker with a library called PicoMQTT but it tells me that the board version is outdated (I assume it brings the ESP32 board from the Atom Board

error: #error PicoMQTT requires ESP32 board core version >= 2.0.7

How can I check which board is in the Atom Lite definition and how this can be updated.

Thanks
FBP

@fbritop where are you installing the MQTT server?
I have a guide for setting up Mosquitto on an RPI

Atom uses a Pico D4 variant and probably lacks the resources needed of the full esp32’S found in the Core2 controller
