Correct, the drivers on Edision OSmini/mini+/mega (kernel 4.8) return new DVB API statistics.

I think also XSarius returns new DVB API statistics (didn't check yet).

With above Enigma2 uses the dB and % as reported by drivers.

if this usefull for some apps :) Enigma2 :) Here is the usage in userspace: + for(unsigned int i=0; i<prop[0].u.st.len; i++) + { + if (prop[0].u.st.stat[i].scale == FE_SCALE_DECIBEL) + signalqualitydb = prop[0].u.st.stat[i].svalue / 10; + else if (prop[0].u.st.stat[i].scale == FE_SCALE_RELATIVE) + ...

but not fix the issue we have with 5520 multistandard tuner my hardware profi say its issue with stream transport through usb but we cant debug this so we need from tbs driver team help to fix this issue Sorry I have no idea what is wrong with USB errors. USB errors also occurs on TBS5980 / TBS5925...

use dvb-fe-tool -m but need install open-source drivers - https://github.com/tbsdtv/linux_media/wiki P.S. Open-source stv090x driver report legacy SNR(%) = SNR(dB) * 5, Strength(%) = 100 + RFLevel(dBm) @crazycat, can we put both relative and dB scaling to drivers please? I can send patch if you fin...

we create a patch and tbs5520 now works with mipsel but we test with kernel 4.01 and 4.7.6 and have usb issue any works not good have you a idea for this issue https://youtu.be/3q0SU7K-rSQ 0001-tbs5520-frontend-capabilities.zip It's really great the idea of returning different capabilities per mode...

Thanks @crazycat,

Regarding the SEC_VOLTAGE_OFF, why is missing from most TBS tuners? It seems that 0x02 is the correct command.

I also thing that we are sending 13V when fe_sec_voltage is SEC_VOLTAGE_OFF.

Hi, Is it possible to control the loop out of TBS5925? Here is the same question for TBS6925. As it is now the loop through works only on the same band and polarity the 6925 is locked on. Same applies to TBS5925? Does it make any sence to use SEC_VOLTAGE_OFF? Because with SEC_VOLTAGE_OFF loop is com...

It seems that there is another patch on patchwork.linuxtv from updatelee that makes blindscan-s2 to work ;) https://patchwork.linuxtv.org/patch/19387/ root@osmini:~# ./blindscan-s2 -b -a 1 frontend: (STV090x Multistandard) fmin 950 MHz fmax 2150 MHz min_sr 1000 Ksps max_sr 45000 Ksps 922 H 27561 SIG...

Hi crazycat, I saw that TBS5980 is supported by v4l-updatelee and listed as blindscan capable. Although there are huge changes in stv090x.c comparing with kernel 4.5 Currently I am using patches from patchwork for TBS + mis/pls +dB + ts sync in stv090x and the following patch to enable algo BS on de...
