MicroPython on ParticleIO Argon ESP32

Post by ttmetro » Sat Feb 16, 2019 9:06 pm

I've flashed esp32-20180511-v1.9.4.bin to the ESP32 on the ParticleIO Argon using Adafruit's mini-ESP tool. I've successfully flashed other binaries using this tool, so I expect (?) that it flashed MicroPython correctly also. The UART connection between the nRF52840 also seems fine. E.g. I can enter the bootloader on reset and get a valid response.

FYI: this works as expected. I have not done much with it yet, but maybe others find this interesting.

(The original message described a problem I had. Turned out a mistake in the setup.)

FYI: the ParticleIO Argon uses an nRF52840 with an ESP32 attached as a WiFi modem via UART.

After googling the board it looks like your flashing the firmware to the main processor the nRF52840 not the ESP32

No.
The nRF is running MicroPython itself. This is how I access the esp32 which is not directly accessible (Making debugging harder).
