Hi
I also own the T230C , trying to use tvheadend on RPI2 LE7.0.2
i'm using crazycat's drivers and copied the fw files to /storage/.config/firmware as suggested in this thread
however after adding the network and muxes, the scan result is "FAIL" (DVB-T)
i dumped tvheadend log, here:
2016-10-31 12:01:10.171 [ INFO]:subscription: 000D: "scan" subscribing to mux "514MHz", weight: 6, adapter: "Silicon Labs Si2168 : DVB-T #0", network: "IdanPlus", service: "Raw PID Subscription"

it doesn't make sense there is no data 
this is the correct broadcast frequency..
is this a known issue? any suggestions how to scan properly? or at least test this manually?
thanks a lot,
Daniel.
