Description

T-LoraPager is a handheld AIOT programmable development device launched by LILYGO, integrating ESP32-S3 high-performance Wi-Fi/Bluetooth dual-mode chip with multiple wireless communication modules. The device features a compact appearance and foldable external antenna design, ensuring wireless performance while maintaining aesthetics. Multiple version options are provided, mainly differing in LoRa modules (LR1121, SX1262 or CC1101), allowing users to choose according to application requirements.

The development board is feature-rich, integrating QWERT keyboard, AI-enabled IMU (BHI260AP), 2.33-inch strip screen (480×222 resolution), U-blox GPS module (MIA-M10Q), RFID/NFC, RTC circuit, TI power management chip, ES8311 audio codec (supporting microphone, speaker, headphone), rotary encoder, GPIO expansion interface, etc. The back design includes 1/4 fixed screw interface and M2 screw pillars, with a lanyard included for easy carrying and fixing. The factory firmware includes UI Demo designed by LILYGO, enabling smooth interaction through the encoder, suitable for smart wearables, IoT positioning, data collection and other scenario development.

Overview

Quick Start

Example Support

PlatformIO

1. Install Visual Studio Code.
2. Search for and install "PlatformIO IDE" in extensions.
3. Download T-LoraPager project code from GitHub.
4. Open the project folder in VS Code, edit the platformio.ini file to select the desired environment.
5. Connect the device, compile and flash the program.

Arduino

1. Install Arduino IDE
2. Install Arduino ESP32 V3.3.0-alpha1 or higher or latest version

• Tip: Arduino Manager URL: https://espressif.github.io/arduino-esp32/package_esp32_dev_index.json

3. Download LilyGoLib library
4. Open Arduino IDE -> Sketch -> Include Library -> Add .ZIP Library -> Select the library zip file downloaded in step 3
5. Install LilyGoLib-ThirdParty
   • Copy all directories from LilyGoLib-ThirdParty to the ArduinoIDE libraries directory. If there is no libraries directory, please create it manually.
   • Please note: do not copy the LilyGoLib-ThirdParty directory itself, but copy all folders under that directory to the libraries directory
   • How to find library file location on your computer, please refer here
     • Windows: C:\Users\{Username}\Documents\Arduino
     • macOS: /Users/{Username}/Documents/Arduino
     • Linux: /home/{Username}/Arduino

Please note that the libraries in LilyGoLib-ThirdParty are not necessarily the latest versions. Before confirming the hardware is working properly, please do not upgrade the dependent library versions.
ArduinoIDE will prompt that new library versions are available for upgrade every time it opens.
Please confirm normal operation before attempting to update to the latest versions. If you encounter issues, please revert to the dependent library versions that worked properly.

6. File -> Examples -> LilyGOLib -> helloworld
7. Tools -> Board -> esp32, please select the corresponding configuration from the table below

8. Board Revision Option, please select according to the actual purchased RF type. Current options include:
   • Radio-SX1262(Sub 1G LoRa)
   • Radio-SX1280(2.4G LoRa)
   • Radio-CC1101(Sub 1G (G)MSK, 2(G)FSK, 4(G)FSK, ASK, OOK)
   • Radio-LR1121(Sub 1G + 2.4G LoRa)
   • Radio-SI4432(Sub 1G ISM)
9. Select Port
10. Click Upload, wait for compilation and writing to complete
11. If unable to upload the program or the USB device keeps popping up on the computer, please manually put the device into download mode. How to enter download mode, please refer to here

• If there is no serial message output, please check if USB CDC ON Boot is set to Enabled.
• The board revision varies according to the actual RF module model. The current default version is SX1262.
• This library depends on the latest arduino-esp32 version. If it is lower than V3.3.0-alpha1, it will report an error.
