GTMedia GTC S905D


#1

I installed the latest CoreElec on my GTC, I use the gxl_p231_2g_dvb.dtb.
To enable the display, install the OpenVFD service from the CoreElec repository and put this file in /storage/.config/vfd.conf. Configure the openVFD service with a Display Brightness of 2. My box is very bright at the default level 7.
I also made an custom keymap. Put the file gtc in /storage/.config/rc_keymaps/gtc
Rename /storage/.config/rc_maps.cfg.sample to /storage/.config/rc_maps.cfg and add

meson-ir        *       gtc

to /storage/.config/rc_maps.cfg

The tuners look detected, but tvheadend can’t see them (no frontend for adapter0 ?). It works fine with a AstroMeta RTL2832.

Hello,
Just to ask if CoreElec team going to support this device in the future and especially the drivers for internal tuners?
Thanks in advance.


#3

I’m considering buying a new STB but I’m not sure what to get. Can you give me more information about the tuners? (internal/external), drivers and etc

I want to use DVB-S2 with TVHeadend.

Thank you!


#4

None of our developers have access to this device so we can’t add support for the internal tuners.

Buy a device that is already supported like the Mecool KIII.


#5

@adamg
What do you mean?
None of your developers team have physically this device, or you just have no acces to the driver’s code from the manufacturer?


#6

If it is the first one, then we can help and donate it. For sure, there are people among us that are interested.

Can any of the developers join the discussion?
