Manually specify OTA ports in arduino Ide ?

[penfold42]

My laptop has a firewall I can't administer and it blocks UDP 5353 inbound.
This stops AirTunes but also stops the OTA advertisements making it it.

How can I manually fake the existence of the ESP devices so they show up in the ide ?

Thanks !

+1 vote to add OTA port(s) into arduino IDE manually.

@penfold42 is this issue still valid? I understand that ArduinoOTA advertises using mDNS, and that you can specify which port to use. This is done in your code.

[penfold42]

Yes, still an issue.

A way to fake / manually add the entries would be great

I guess this is more of an IDE issue than ESP8266 then? I.e. it applies to any board which uses mDNS for OTA, not just the ESP8266.

Yes - I didn't realise the OTA subsystem is a base arduino IDE capability.

Actually I don't think opening the 5353 port does solve the issue (I've tried adding a rule and it still fails the uploading process).

I tried using the CLI command:
python .arduino15/packages/esp8266/hardware/esp8266/2.3.0/tools/espota.py -i HOSTIPADDR -p HOSTPORT -I REMOTEIPADDR -P REMOTEPORT -f SKETCH.bin
and it JUST works (by adding a rule for HOSTPORT)

It would be great to be able to specify one port to listen onto, maybe in a config file

SOLVED!

In file ".arduino15/packages/esp8266/hardware/esp8266/2.3.0/platform.txt"

change line:
tools.esptool.upload.network_pattern="{network_cmd}" "{runtime.platform.path}/tools/espota.py" -i "{serial.port}" -p "{network.port}" "--auth={network.password}" -f "{build.path}/{build.project_name}.bin"

to:
tools.esptool.upload.network_pattern="{network_cmd}" "{runtime.platform.path}/tools/espota.py" -i "{serial.port}" -p "{network.port}" -P 8266 "--auth={network.password}" -f "{build.path}/{build.project_name}.bin"

this way the LISTENING port on your development pc is fixed to 8266 (of course you can change it) and you can write a rule on your firewall

[atrent]

better yet!

in "preferences.txt" add

ota.hostport=8266

and in file ".arduino15/packages/esp8266/hardware/esp8266/2.3.0/platform.txt" change the line in:

tools.esptool.upload.network_pattern="{network_cmd}" "{runtime.platform.path}/tools/espota.py" -i "{serial.port}" -p "{network.port}" -P "{ota.hostport}" "--auth={network.password}" -f "{build.path}/{build.project_name}.bin"

@devyte

he said, earlier that 5353 was being blocked

[herrold@centos-7 ~]$ grep 5353 /etc/services
mdns 5353/tcp # Multicast DNS
mdns 5353/udp # Multicast DNS

actually I would make the default in @atrent 's proposal, the IANA assigned $DEFAULT of 5353, rather than a local side port

@penfold42

This issue is in a closed state -- could you please re-open it so it does not get forgotten, and gets documented

[atrent]

of course, you can change the config to any port you want :)

[atrent]

actually, let me say that 5353 should NOT be used since it's dedicated to mdns service, while the upload of the new sketch via network is another service altogether, i.e. we should use an "unused" port

mdns is a discovery service, it's needed to find the device, the following communication is another story
