Does OTA work in arduino-cli?

[brusherru]

I see networkBoards list when I call arduino-cli board list --format json, but it's always empty, even when I see the board in the Arduino IDE.

I tested it with esp8266:esp8266:wifi_slot board on MacOS Sierra.

I see that you are using monitor.Network() in the board/list.go, so I assume it should work. But it's not.

Is this a real bug or it just not implemented yet?

+1 on this issue. The code seems to already support OTA, but boards are not listed.

I have a MKR1010 which is correctly recognized for OTA by Arduino IDE, while CLI (preview 0.32) does not list it.

Here's a makefile snippet that provides a temporary workaround for doing OTA with the CLI:

Use make find to list network boards, and make ota to upload. Make ota takes board hostname, eg make ota DEVICE=alice. If you want to skip the zeroconf query and use the ip, do make ota IP=1.2.3.41

ota: $(OBJ)
	@if [ -z "$$IP" ] ; then \
		IP=`avahi-browse -ptr  "_arduino._tcp" | egrep ^= | cut -d\; -f4,8,9 | grep ^$$DEVICE | cut -d\; -f2` -p `avahi-browse -ptr  "_arduino._tcp" | egrep ^= | cut -d\; -f4,8,9 | grep ^$$DEVICE | cut -d\; -f3` ;\
	fi ;\
	python $(OTAPROG) -i $(IP) "--auth=$(OTAPASS)" -f $(OBJ)

find:
	@if [ `uname -s` = Darwin ] ; then \
		dns-sd -B _arduino._tcp ;\
	else \
		avahi-browse -ptr  "_arduino._tcp" | egrep ^= | cut -d\; -f4,8,9 ;\
	fi

@brusherru yes it can work

Roberto from Arduino Team here,
Currently OTA support is not included in the CLI.
Our plan is to implement a "Pluggable discovery" feature in the near future that will allow to support OTA.

Workarounds are possible as @unixbigot reported, but there is no CLI native support ATM.

Cheers!
