ESXP1302 = ESP32 + SX1302.

ESXP1302 is a low cost 8 channel LoRa gateway design, based on ESP32 platform and porting of SX1302_HAL, based on the latest Version 2.1.0.

There are two ways to compile this project.

PlatformIO is a development environment that enables easy multi-platform development and centralized tooling. PlatformIO IDE bases on Visual Studio Code.

Follow these steps to compile ESXP1302 and flash the produced firmware.

• Clone this project with: git clone https://github.com/lora-gateway/esxp1302.
• Open the newly cloned folder in VS Code. If you do this for the first time, this can take quite some while as PlatformIO will download all the necessary tooling and libraries. Also if platformio is not installed, VS Code will ask you to install it.
• Open your command palette with below shortcuts:
  • Windows/Linux: Ctrl + Shift + P
  • Mac: Command + Shift + P
• To build the firmware, simply run PlatformIO: Build from your command palette.
• To flash the firmware to your device, just run PlatformIO: Upload from your command palette.

You need ESP32 development environment esp-idf.

Please follow the guide to install the SDK and the tools, or just follow below simplified steps:

git clone --recursive https://github.com/espressif/esp-idf.git
cd esp-idf
git checkout v4.4.5  # this branch surely works; the latest v5.x branches not yet
git submodule update --init --recursive

# below 2 steps are for Linux. For windows, use `install.bat` and `export.bat` instead.
./install.sh  # install the compilers etc.
. export.sh   # export and set up the environment

Then compile this project follow below steps:

git clone https://github.com/lora-gateway/esxp1302
cd esxp1302
./run_me.sh make  # compile
./run_me.sh flash_all  # flash 3 images: bootloader, partition_table and esxp1302
# ./run_me.sh flash  # use this to only flash esxp1302 firmware

Script run_me.sh can compile the code, flash the ESP32 board, and open minicom to monitor the output, so make sure your ESP32 board is connected. If you are not under Linux, you need to change run_me.sh to use other terminal tool instead or just run your terminal tool manually.

Run ./run_me.sh -h for its whole usage.

There are 2 compile targets:

• main/packet_forwarder/lora_pkt_fwd.c. This the default target.
• main/libloragw-test/cli4test.c. This provides a command line interface to support several test commands.

It's controlled by flag CONFIG_LIBLORAGW_TEST. Change the value to "1" in run_me.sh to switch to the second target.

At the terminal, you should be able to input the command with your argument of option, such as:

test_loragw_hal_tx -r 1250 -c 0 -f 505.5 --pwid 22 -b 125 -n 20
test_loragw_hal_tx -r 1250 -c 0 -f 505.5 --pwid 22 -b 125 -n 20 -m CW
test_network_connection -u wireless_ssid -p wireless_password --host 192.168.1.200 --port 2000
pkt_fwd -u wireless_ssid -p wireless_password --host 192.168.1.200 --port 1680

All kinds of documents (user guide, changelog, todo list etc.) are available from doc folder.
