Hi all,
I am using umtrx (2.1) with with osmo-trx and osmobts-trx. I have two 
problems.
i) When i power on umtrx, i occasionally cannot reach it, even does not 
respond to ping. After power cycle or pressing reset button, it functions 
normally. Have you come across to this, is it a known problem solved by some 
firmware update etc.
ii) For my working scenario, i sometimes need to stop-pause RF completely in 
order to change some parameters and save energy, and restart later when 
needed. From osmobsc down-to osmobts, I see "rf mute" function for sysmocom 
devices but not implemented something similar for umtrx or for libuhd 
generally. Even if I close osmo-trx application, using an RF scanner I can see 
RF signal on last configured frequency. Is there a way to stop RF of the device 
completely without powering it down. (I tried uhd_device::stop which is 
normally called in destructor, but cannot get the expected result)

regards,
yavuz
