Keep bias tee power on when using srsLTE
Is there a method to keep bias tee on? The bias can be turn on using CLI but when I use srsLTE (enb), it will reset everything from CLI setting. how can I keep the setting? Is there an option in config file that can turn bias power on just like in GNU Radio block? Otherwise, I have to do a lot of wiring to feed fours amplifier at the bladeRF port. Thank you

I am having the same problem with the bt-100 and bt-200 turning off/resetting upon startup of srsenb. A software solution would be helpful.

Re: Keep bias tee power on when using srsLTE
You can use the bladeRF config file to control the biastees. Please take a look at https://nuand.com/bladeRF-doc/libbladeR ... gfile.html
For example putting the following in bladeRF.conf should default the bias tees to on:

Like this command.
bladeRF> set clock_sel external
Clock input: External via CLKIN

Re: Keep bias tee power on when using srsLTE
Yep, I put
clock_ref enable
refin_freq 10M
or
clock_sel external
in /usr/share/Nuand/bladeRF/bladeRF.conf along with the bias tee commands and it works.
However you have to comment out all the commands when loading new firmware or fpga image or it wont load.
When you have the firmware or fpga loaded you just uncomment the lines and run srsenb.
Cheers
