Compilation Raspberry

[zoipod]

Hello,
I want to use your app on my raspberry, to connect with my domotic app.
When I compile source code, I receive an error :
$ go build
github.com/McKael/samtv/cmd
../../src/github.com/McKael/samtv/cmd/tui_keybindings.go:95: undefined: strings.Builder

My version of go :
$ go version
go version go1.7.4 linux/arm

Have you a solution to compile with this version ?
(I know go since yesterday ^^)

Thx

[McKael]

Is it acceptable for you to use a newer compiler? (strings.Builder was introduced in Go v1.10 AFAICT...)

For example, you can download a copy of go 1.11 and use it with:

$ go get golang.org/dl/go1.11
$ go1.11 download

... and then use:

$ go1.11 build

to build this project.

(BTW a prebuilt binary is available in the release files)

Well, it's ok with this version of Go. Thx you.

When I send key, it's ok on TV, but I receive an error.

$ samtvcli key KEY_VOLUP
INFO[0000] Using config file: /home/pi/.config/samtvcli/samtvcli.yaml 
ERRO[0004] Cannot send key 'KEY_VOLUP': incorrect TV reply 

Reply it's not important, because it works, but I think, I can't send multi key.

$ samtvcli key KEY_SOURCE _ KEY_RIGHT
INFO[0000] Using config file: /home/pi/.config/samtvcli/samtvcli.yaml 
ERRO[0006] Cannot send key 'KEY_SOURCE': incorrect TV reply 

key "KEY_RIGHT" is not send, surely due to this error..

Have you an idea ?

[McKael]

@zoipod No, I don't have an idea... I don't get this with my own TV.

Can you send me the debug output?

samtvcli --debug key KEY_VOLUP

In the mean time, since it works for you I could also add something like a --ignore-result flag, maybe?

[zoipod]

@McKael Hi, this is the debug mode :

$ samtvcli key KEY_SOURCE _ KEY_RIGHT --debug

I just found key KEY_HDMI, so I can change source with it.

Last question, if I power off the TV, I have to pair to get a new session ?
Or the first paring is definitive ?

[McKael]

Thanks for the trace, I'll push a fix!

With my TV, the pairing is lost when the TV is completely powered off or rebooted, but it stays paired when using the usual stand-by mode.

[McKael]

@zoipod Hopefully this should be fixed now.

[zoipod]

Just perfect !
Thank you

[McKael]

Great, thanks!
