[Sirogha]

Hello

I have TCL tv (android TV). I try use your algorithm (url) and get error from TV, when send 1st Configuration Message (steps):

1) When my app connect to TV via 6466 port, i got packet from TV. 85,10,83,8,253,4,18,78,10,12,83,109,97,114,116,32,84,86,32,80,114,111,18,3,84,67,76,24,1,34,2,49,49,42,36,99,111,109,46,103,111,111,103,108,101,46,97,110,100,114,111,105,100,46,116,118,46,114,101,109,111,116,101,46,115,101,114,118,105,99,101,50,13,53,46,50,46,52,55,51,50,53,52,49,51,51 (dec) 550A5308FD04124E0A0C536D6172742054562050726F120354434C1801220231312A24636F6D2E676F6F676C652E616E64726F69642E74762E72656D6F74652E73657276696365320D352E322E343733323534313333 (hex) remote_configure { code1: 637 device_info { model: "Smart TV Pro" vendor: "TCL" unknown1: 1 unknown2: "11" package_name: "com.google.android.tv.remote.service" app_version: "5.2.473254133" } } 2) I try to send configuration message. This packet have small error - androitv-remove instead androidtv-remote, but androidtv-remote not work too. 36,10,34,8,238,4,18,29,24,1,34,1,49,42,15,97,110,100,114,111,105,116,118,45,114,101,109,111,116,101,50,5,49,46,48,46,48 (dec) 240A2208EE04121D18012201312A0F616E64726F6974762D72656D6F74653205312E302E30 (hex) remote_configure { code1: 622 device_info { unknown1: 1 unknown2: "1" package_name: "androitv-remote" app_version: "1.0.0" } } 3) I got packet from TV with error. 42,26,40,8,3,18,36,10,34,8,238,4,18,29,24,1,34,1,49,42,15,97,110,100,114,111,105,116,118,45,114,101,109,111,116,101,50,5,49,46,48,46,48 (dec) 2A1A28080312240A2208EE04121D18012201312A0F616E64726F6974762D72656D6F74653205312E302E30 (hex) remote_error { value: true message { remote_configure { code1: 622 device_info { unknown1: 1 unknown2: "1" package_name: "androitv-remote" app_version: "1.0.0" } } }

Sorry, I cannot help.

I know it's very painful and I did my best to provide a documentation based on what I discovered. But it's really difficult to make it work.

I guess that if you're at the step to send on 6466, it means you succeed with the pairing step… Maybe you can verify you don't send too early the packets, and that you send them in the correct order... Other than that, I cannot help.

You could also play with the JS implementation that works great and could help: https://github.com/louis49/androidtv-remote

Good luck!
