Hi,
In Rev 7 of the PTS pg53 5 : Power
Required Shutdown Sequence.
Is this function can be replaced by AT command “!POWERDOWN” then power off the VCC ?
- Perform the at command “!POWERDOWN”.
- Wait for at least t_pwr_off_seq seconds.
- Remove power.
Many thanks,
Jerry
Hi Jerry,
AT!POWERDOWN is a legacy soft power down sequence that is not supported in the latest AT command document. The firmware will acknowledge the command but it doesn’t shutdown the module. The document you sent me is a legacy AT command document for Qualcomm-based modules that were for 2G/3G. not LTE.
