Hi, I have been experimenting with upload_protocol in the platformio.ini lately.
And noticed that I can remove upload_protocol completely.
platformio automagically choose esptool + “aut detect” if if upload_port is blank
upload_port =
And platformio choose espota if it detects an ip as upload_port.
upload_port = 10.199.1.62
So far so good.
But when i involve a pythonscript I get another behavior.
pythonscript:
Import("env")
env["UPLOAD_PORT"] = "10.199.1.62"
This does not work until i specify “upload_protocol = espota” in platformio.ini.
with upload_protocol still removed from platfomrio.ini:
pythonscript:
Import("env")
env["UPLOAD_PROTOCOL"] = "espota"
env["UPLOAD_PORT"] = "10.199.1.62"
i got this result:

Configuring upload protocol...
AVAILABLE: cmsis-dap, esp-bridge, esp-prog, espota, esptool, iot-bus-jtag, jlink, minimodule, olimex-arm-usb-ocd, olimex-arm-usb-ocd-h, olimex-arm-usb-tiny-h, olimex-jtag-tiny, tumpa
CURRENT: upload_protocol = espota <<------!
Looking for upload port...
Using manually specified: 10.199.1.62
Uploading .pio\build\esp32-poe-iso\firmware.bin
esptool.py v4.5.1 <<-------!
Serial port 10.199.1.62
something is accepting >> env["UPLOAD_PROTOCOL"] = "espota" << but ignores it and choose esptool anyway.
I dont get this.
Help is highly appreciated
