Restrictions using commands from Ticon tool to calibrate WL1271 module
I have a question related with
the calibration and continuous Tx/RX of the WL1271 module. The doubt it's about
restrictions that could exist while using the different commands available for
For example, to
start the calibration on a specific sub-band (TX bip option) it's necessary to
tune the channel that is needed before any Rx or Tx operation to inform the
firmware where to receive/transmit (channel tune option). The doubt is: Is
there a min/max amount of time (delay) that it's necessary to wait between
commands? (for all the commands that the Ticon tool supports). I'm asking
this because when I had been running the Ticon tool passing an script file some
of the commands failed. For Ex:
"Script 1" (ticon.exe -s
/ w p 1 l 2 f 2
/ t r h 0 7
/ t b b 423 128 0
/ t b t 1 0 0 0 0 0 0 0
If I try to run that
specific sequence in one script I got some error messages after tuning the
channel (the error appears when this command line is executed / t b b 423 128
0), but if I split the script in two and then run both command lines (ticon.exe
-s \windows\Script1.txt and then ticon.exe -s \windows\Script2.txt) the error
is not present.
That's why I have the
doubt about any min/max amount of time restriction between commands. I can see
that when command lines are executed one after another it's necessary to have a
delay between commands. Probably the channel tuning (/ t r h 0 7) is still
modifying the firmware when the command line that updates buffer calibration
reference executes (/ t b b 423 128 0).
I also had been checking
some of the code related on how to do the calibration of the firmware but I
couldn't find any time restriction in the application code. Besides I had been
trying to find some information like this but it's not documented in the user
guides that I have available right now. Do you know if there's any document
with that type of content?
