1. Install the current upstream Arduino IDE at the 1.8 level or later. The current version is at the Arduino website. (NOTE: MacOS may require that you install separate drivers to interact with your board. You will get error messages that occur when the IDE attempts to upload code. You should consider running the Arduino IDE in a Virtual Machine on Linux. Installing other drivers on your Mac is out of scope for this document.)
2. Start Arduino and open Preferences window. In additional board manager add url: https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json If you have multiple URLs (e.g., for other boards), just add previously mentioned URL, separated by a comma.
3. Copy all folders in the libdeps directory to your Arduino Libraries Directory,

• in MacOS, it is ~/Documents/Arduino/libraries
• in Linux, it is ~/Arduino/libraries
• in Windows, it is Documents/Arduino/libraries

4. Open the corresponding example
5. In the Arduino Application, navigate to the Board Manager menu ("Tools => Board => Board Manager"), search for esp32, and make sure that you install the latest version. After you do this, you can select the board you have from the list of boards in the "ESP32 Arduino" menu ("Tools=> Board => ESP32 Arduino"). It's very important to note that the list of boards is NOT in alphabetical order. Look for the board you are working with carefully in the list. T-Beam users can choose TTGO T-Beam, lora32(T3) users can choose ESP32 Dev Module , T-Motion users choose Nucleo_l073RZ
6. Select the port of the board in the port
7. For other examples except the GPS directory, please uncomment in the upper part of utilities.h according to your board model, otherwise the compilation will report an error
8. Upload

How to distinguish the model of Radio just need to look at the sticker on the board, 433MHz is SX1278, 868MHz is SX1276, If the label says SX1262 then it is SX1262

1. If there is no data output from GPS, see Restoring factory defaults

• See utilities.h

• T-Beam SoftRF
• T-Beam Paxcounter
• T-Beam Meshtastic

To quickly start using TTN (The Things Network), please refer to LilyGo_LoRa_Series_Quick_Start

• AXP192
• SX1262
• SX1278
• SX1276
• SX1280
• GSP NEO-6/NEO-8

1. After setting the LoRa output power, set the lowest current. Set sx1262 as follows :

    // digitalWrite(LoRa_Busy, LOW);
    // set output power to 10 dBm (accepted range is -17 - 22 dBm)
    if (radio.setOutputPower(22) == RADIOLIB_ERR_INVALID_OUTPUT_POWER) {
        Serial.println(F("Selected output power is invalid for this module!"));
        while (true);
    }


    // set over current protection limit to 80 mA (accepted range is 45 - 240 mA)
    // NOTE: set value to 0 to disable overcurrent protection
    if (radio.setCurrentLimit(80) == RADIOLIB_ERR_INVALID_CURRENT_LIMIT) {
        Serial.println(F("Selected current limit is invalid for this module!"));
        while (true);
    }
