I connected Lepton 3.5 to Adafruit ESP32 Feather and I used this code (https://github.com/NachtRaveVL/Lepton-FLiR-Arduino/blob/master/examples/AdvancedExample/AdvancedExample.ino) in Arduino (it is an example of the library I am using: https://github.com/NachtRaveVL/Lepton-FLiR-Arduino).

So my problem consists of reading the frames of the camera. With this code, I can't have any results on Serial Monitor, but if I remove the condition "if (flirController.readNextFrame())", the Serial Monitor is constantly showing me the results of the first frame, instead of showing me the results continuously.

I have already changed the baud rate and the clock but the results are the same.

Can anyone help me?

This is my setup between the PureThermal 2 board (with the built-in Lepton 3.5) and my microcontroller (Adafruit ESP32 Feather). Am I doing something wrong? What is missing?
