Remote firmware update?

[zenmanenergy]

Is it possible to upgrade the codebase so we can remotely upload new firmware?

[lukecyca]

It should already be possible, but you would need to do it by calling the underlying functions directly. The IoT SDK has a series of system_upgrade_* functions, and Sming has a module called
HttpFirmwareUpdate and an example which might be good starting points.

It would great to eventually expose this through the ESP object with a more user-friendly API.

Holy crud. That looks fucking awesome!! Thank you!

We now have parts of OTA update infrastructure ready. Uploads of sketch from the IDE over WiFi are not ready yet, but here is an example sketch which can be updated using a python script:

sketch: https://gist.github.com/igrr/43d5c52328e955bb6b09

python script: https://gist.github.com/igrr/d35ab8446922179dc58c

EDIT: you need to use either the staging release or build from git to use that feature: http://arduino.esp8266.com/staging/package_esp8266com_index.json

I'm interested on that, the bin I have to upload is the one finished by cpp_10000.bin?

[pablotix20]

I can't upload:
C:\Users\pablo_000\Downloads>python ota_server.py 192.168.1.25 Wifi_temp_post.cp
p_00000.bin
Traceback (most recent call last):
File "ota_server.py", line 64, in
sys.exit(main(sys.argv))
File "ota_server.py", line 59, in main
return serve(args[1], args[2])
File "ota_server.py", line 19, in serve
print >>sys.stderr, 'starting up on %s port %s' % server_address
TypeError: unsupported operand type(s) for >>: 'builtin_function_or_method' and
'_io.TextIOWrapper'

EDIT: Works on linux (Ubuntu)

I think this print statement stuff will not work with python 3. I've written this script with 2.7.

[pablotix20]

OK thanks, on Ubuntu iḿ using 2.7.9, I'll see on Windows

Regarding the bin file, there is now only one .bin file generated (like Blink.cpp.bin)
You need to use either git version or this package:

I cannot update:

socket.error: [Errno 10054] Se ha forzado la interrupci¾n de una conexi¾n existente por el host remoto

I have searched in Google but it seems that the connection is closed by the ESP and i have also tried with HERCULES for windows to see if it sended it and the python programm sended it correctly

You have the OTATest.ino sketch loaded?

Yes, it shows Update failed when the cmd shows the error

Can you please post complete output from both sides?
Also it would be helpful if you would mention what kind of board you are using, what is the flash size, what is the size of the sketch you are trying to load via OTA. Thanks.

This is way cool! I have ESP's that are built into walls behind switches
and upgrading is a....
So this'd be great!

this seems to work here :)
that it resets the module (wdt) is what is supposed to happen after it is finished uploading ?

[pablotix20]

Here is the log and the bin file:

I have also tried uploading the blink example with no success
