In AT Command Reference r8.pdf document page 96, AT!POWERMDOE, it mentioned ULPM is not supported by WP77xx module variants. MangOH Yellow Octave dashboard indicated the HW module is WP7702. Does that mean ULPM is not supported by MangOH Yellow?
I set ULPM timer and use Octave to send shutdown command, but MangOH Yellow did not enter ULPM.
I used AT!powerwake=1,120,120,2 to set ULPM timer, and used AT!powermode=3 to test ULPM.
MangOH Yellow did enter ULPM and wakeup after 120sec.
However, the PSM Timer got changed to 14400sec after wakeup.
300sec was from the Octave setting I created. Not sure how PSM Timer was changed to 14400sec.
So AT!powermode=3 command works OK.
However, when I tried ULPM shutdown command from Octave, nothing happened. MangOH Yellow did not go into ULPM.
AT!powermode? and AT!powerwake? stay the same. Looks like {“util/ulpm/shutdown”:1} did not take effect at all.
