I am trying to use the QT GUI Entry block to change variables while a
program is running. However, I have discovered that when I change the
variable defined by the Entry block, the program crashes, displaying
the error: AttributeError: 'unicode' object has no attribute
'toAscii' I am running GNU Radio Companion 3.7.11.
I have attached a very simple .grc program that illustrates the
problem. The program consists of a cosine signal source feeding into a
QT GUI Time Sink. The frequency of the signal is controlled by a QT
GUI Entry block. Trying to change the frequency while the program is
running will cause a crash.
Anyone familiar with this problem?
Thanks!
