HTIT-WSL is a development board for Wi-Fi, Bluetooth and LoRa. Because some customers do not need OLED screen when using WiFi Lora32, we launched this product.
The HTIT-WSL is composed up of an MCU (ESP32-S3FN8) and Semtech LoRa Transceivers (SX1262), perfectly support Arduino®. Users can easily carry out secondary development and application.

If you want to use the new ESP32-S3 processor and the SX1262 LoRa chip, you may need to use new libraries that support them. You should check that the libraries you are using are compatible with these new components.
As far as my experience with the Wireless Stick Lite is concerned, the only library I had to change when switching from V1 to V3 was the LoRa library. The Sandeep Mistry LoRa library that I used earlier doesn’t work with the new SX1262 LoRa chip. To make my code work with the V3, I had to migrate to the Heltec LoRaWan_APP library. This was a true migration because the two libraries don’t use identical calls.
Imagine that you want to measure the moisture in your field. Although, it is not far from your house, it probably doesn’t have Wi-Fi coverage. So, you can build a sensor node with an ESP32 and a moisture sensor, that sends the moisture readings once or twice a day to another ESP32 using LoRa.The later ESP32 has access to Wi-Fi, and it can run a web server that displays the moisture readings.This is just an example that illustrates how you can use the LoRa technology in your ESP32 projects.
