1. Install ESP-IDF (Espressif IoT Development Framework)

   • If error unrecognized arguments: --no-site-packages then remove --no-site-packages from line 1181 so that the line looks like:

       subprocess.check_call([sys.executable, '-m', 'virtualenv', idf_python_env_path],
     

   • rerun ./install.sh
   • run . ./export.sh

2. Follow https://github.com/pjalocha/esp32-ogn-tracker

   • Get the config for OLED screen: cp T-Beam_v10_OLED.cfg main/config.h

   • source esp-idf with source ~/esp-idf/export.sh in order to be able to run make command

   • use ls /dev/tty* | grep usb to discover serial ports (e.g. when TTGO connected via USB-C adapter)

   • flash with proper port name: make flash ESPPORT=/dev/tty.usbserial-0212BE43

   • AFAIK this is not needed if above step is applied

     • /dev/ttyUSB0 is not available on MacOS, it is /dev/tty.SLAB_USBtoUART change the --port param to use /dev/tty.SLAB_USBtoUART in the following flash command:

       python /Users/philippe/git/esp-idf/components/esptool_py/esptool/esptool.py --chip esp32 --port /dev/tty.SLAB_USBtoUART --baud 921600 --before default_reset --after hard_reset write_flash -z --flash_mode dio --flash_freq 40m --flash_size detect 0x1000 /Users/philippe/git/esp32-ogn-tracker/build/bootloader/bootloader.bin 0x10000 /Users/philippe/git/esp32-ogn-tracker/build/app-template.bin 0x8000 /Users/philippe/git/esp32-ogn-tracker/build/partitions.bin
       

   -brew install minicom -man minicom // shows the path at the bottom minirc.dfl (/usr/local/Cellar/minicom/2.8/etc) /usr/local/Cellar/minicom/2.8/etc/

   • /dev/tty.SLAB_USBtoUART OR
   • /dev/tty.usbserial-0212BE43
   • edit minirc.dfl to set port, baudrate and turn hardware and software handshake OFF

     pu lock /usr/local/Cellar/minicom/2.8/var
     pu escape-key Escape (Meta)
     pr port             /dev/tty.SLAB_USBtoUART
     pu baudrate         115200
     pu rtscts           No
     pu xonxoff          No
     

   • connect with minicom
     • Ctrl-C - lists internal state, internal log files and current parameter values.
     • Ctrl-L - list internal log files
     • Ctrl-V - hold the NMEA stream for 1 min
     • Ctrl-X - restarts the system

3. Install Android IDE with expressif

4. OLED driver SSD1306
