Hello y'all I need you to review the code for my project as I am kind of new to the programming language and the intracies of the esp32-s3. Let me explain you my project : I need an hc sr 501 pir module to detect movement and to wake my esp32 up and send a message via Lora rylr998 protocol. Here is the code and I own an esp32-s3 devkitc1 ESP32-S3-DevKitC-1 v1.1 - ESP32-S3 - — ESP-IDF Programming Guide v5.2 documentation. If you have any improvement I beg you to help. Thank you very much and have a great christmas
