OTA update

[d-solis-tovar]

Hi,

I want to implement OTA updates for my ESP32 microcontroller. I flashed micropython firmware with OTA support (one partition for ota_0 and another partition for ota_1). I'm looking for a procedure like this when running partition is ota_0:

1. Get new firmware .bin from a request to Github or any other server (I created a custom Micropython firmware)
2. Write .bin content into partition ota_1
3. Set partition ota_1 to run at next boot

Right now, I'm stuck trying to at Step 1. I tried to get/download .bin file using urequests.get but it didn't work.

.bin file is 1.6 MB size.

Thank you in advance

You should use the .app_bin files (which can be downloaded from from https://micropython.org/download/?mcu=esp32), not the micropython .bin files, for OTA updates.

See https://github.com/glenn20/micropython-esp32-ota for more details abour the .app-bin files and examples (and a tool to perform ota updates from urls).
