Copy that. Would a preamble with better properties like a gold code allow
to raise that threshold? I guess I need to dig into what that threshold
means. On the examples I’ve seen it’s always 0.9 or higher.

Hi Martin,
Thanks for your information.
If I run the gr_modtool info in another OOT-module dir, I got the
following information:
Module name: gmsktr
API version:
ot; FORCE)
set(GR_ZIGBEESINK_SWIG_INCLUDE_DIRS ${CMAKE_CURRENT_SOURCE_DIR}/swig
CACHE INTERNAL "" FORCE)
# Create uninstall target
configure_file(
${C
right folder to run gr-modtool makexml.
Does anybody meet this problem?
Best regards
Alex

_ZN2gr6filter24mmse_fir_interpolator_ffC1Ev
I have tried two days to find the bug but no progress.does somebody
have experience about this problem? Any suggestions would be appreciated!
Best regards

Hello Josh,
Today I met this problem again.
The gnuradio.extras can not be imported, with error of "pmt_is_null"
undefined in the extras.
even though the gnuraido version I am using is v3.6.5.1.
And the grextras can not be built at all due to some error.

It should be corrected, if I am not wrong.

Hi all,
It is seen that the RSSI can be obtained by the read_aux_adc.
But I am not sure if SBX board supports it or not. And how to specify the
parameters:
int which_side, int which_adc
Any hints for this question?
Thanks!

Oh, it's working with single-thread make...I did not expect this cause for
days.
