Hi Prog, thanks for you're work on this,
You seem to have broken normal mode for me. Tried on both a raspberry pi 3 and and orange pi PC, both of which work with previous versions. Using RTL-SDR.com V3.
If I try to connect when rtl_sampling_mode is either commented out or set to 0 then I cant connect with an error from SDR# 1622
'Server didn't send the device capability and syncronisation info'
This is what the server reports :-
Accepted client 192.168.55.101:57944 running SDR# v18.104.22.1682 on Microsoft Windows NT 6.1.7601 Service Pack 1
Device was sleeping. Wake up!
Found Rafael Micro R820T tuner
Disabled direct sampling mode
Acquired the device
Client disconnected: 192.168.55.101:57944
No clients using the device. Sleeping...
Released the device
If I set rtl_sampling_mode to 1 or 2 I do get connected but obviously in the wrong mode.
