Review on 🔌 HiLetgo UNO R3 D1 R32 ESP32 ESP-32 CH340G WiFi+Bluetooth+UNO Development Board WiFi Bluetooth 4MB Flash with Micro USB for Arduino: A Versatile Solution for IoT Projects by Michael Gutierrez

Works great once I figure it out: I was able to program this board using esptool.py @download.config on the image I downloaded from the espressif site . However, I could not program with the Arduino. The Arduino uses esptool.py to program the board, but it passes a lot of parameters. I hacked the following and voila it worked. It looks like some kind of handshake timing issue. It should be noted that other ESP32 development boards are programmed perfectly with the standard platform.txt file. Please note that this was done in the Linux version. -------------------------------------------------- -------------------------------------------------- -------- To make it work changed the following in /.arduino15/packages/esp32/hardware/esp32/1.0.4/platform.txt FROMtools.esptool_py.upload.pattern.linux=python " { path }/{cmd}" --chip esp32 --port " {serial.port}" --baud {upload.speed} --before default_reset --after hard_reset write_flash -z --flash_mode { build. flash_mode} --flash_freq {build.flash_freq} --flash_size finds 0xe000 "{runtime.platform.path}/tools/partitions/boot_app0.bin" 0x1000 "{runtime.platform.path}/tools/ sdk/bin /bootloader_ {build.boot}_{build.flash_freq}.bin" 0x10000 "{build.path}/{build.project_name}.bin" 0x8000 "{build.path} /{build.project_name}.bin"TOtools.esptool_py.upload.pattern.linux=python "{path}/{cmd}" -- esp32 chip --port "{serial.port} " --baud {upload.speed } - -before default_reset --after hard_reset write_flash -z --flash_mode {build.flash_mode} --flash_freq {b uild.flash_freq} --flash_size detect 0xe000 "{runtime. platform.path}/tools/partitions/boot_app0.bin" 0x1000 "{runtime.platform.path}/tools/sdk/bin/bootloader_{build.boot}_{build.flash_freq}.bin" 0x10000 "{build.path}/{build.project_name}.bin" 0x8000 "{build.path}/{build.project_name}.partitions.bin"
