Hi there,
I’m putting the L76 GNSS module into STANDBY mode periodically for power saving. It will be waken up by a HOT START serial message when needed. However, after have the device running for around 3 days, at some point the GNSS module will fail to wake up from STANDBY mode.
To deal with it, I modify the software from my side to power it off for 1 second, if GPS time hasn’t been updated for more than 10 minutes.
It works for most of devices, but for some testing units I used frequently, it can still fail to wake up the L76 module even by power cycle it.
I’m wondering what’s the reason for L76 module not being able to wake up from the STAMDBY mode occasionally, and will it be fine to cut the power down directly, or is there any commands available to reset that module?
Thanks for your help, looking forward to your response!
