Build & Flash

The same codebase builds either role. Each role has its own build directory so both can coexist.

1. Clone & find your serial port

git clone https://github.com/TN666/batear.git
cd batear
ls /dev/cu.usb*          # note your port, e.g. /dev/cu.usbserial-3

2. Build & flash the Detector

# First time only — set chip target (esp32s3 for Heltec V3)
idf.py -B build_detector \
  -DSDKCONFIG=build_detector/sdkconfig \
  -DSDKCONFIG_DEFAULTS="sdkconfig.defaults;sdkconfig.detector" \
  set-target esp32s3

# Build
idf.py -B build_detector \
  -DSDKCONFIG=build_detector/sdkconfig \
  build

# Flash & monitor (replace PORT)
idf.py -B build_detector \
  -DSDKCONFIG=build_detector/sdkconfig \
  -p PORT flash monitor

3. Build & flash the Gateway

# First time only — set chip target (esp32s3 for Heltec V3)
idf.py -B build_gateway \
  -DSDKCONFIG=build_gateway/sdkconfig \
  -DSDKCONFIG_DEFAULTS="sdkconfig.defaults;sdkconfig.gateway" \
  set-target esp32s3

# Build
idf.py -B build_gateway \
  -DSDKCONFIG=build_gateway/sdkconfig \
  build

# Flash & monitor (replace PORT)
idf.py -B build_gateway \
  -DSDKCONFIG=build_gateway/sdkconfig \
  -p PORT flash monitor

After first setup

Code changes only need rebuild + flash (no set-target):

# Detector
idf.py -B build_detector -DSDKCONFIG=build_detector/sdkconfig build
idf.py -B build_detector -DSDKCONFIG=build_detector/sdkconfig -p PORT flash monitor

# Gateway
idf.py -B build_gateway -DSDKCONFIG=build_gateway/sdkconfig build
idf.py -B build_gateway -DSDKCONFIG=build_gateway/sdkconfig -p PORT flash monitor

Tip

Replace PORT with your actual serial port (e.g. /dev/cu.usbserial-3 on macOS, /dev/ttyUSB0 on Linux).
