Keep bias tee power on when using srsLTE

[fllay]

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.

Have ya'll figured this problem out at all? i'm having significant issues w/ srsLTE. keep getting RX and TX failed warnings from ../rf_blade_imp.c

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:

Code: Select all

biastee_rx true
biastee_tx true

It is working now. Thank you. Is there an option to set external ref. clock as well?

Like this command.

bladeRF> set clock_sel external

Clock input: External via CLKIN

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.
