Immediate power-down after successful LTE upload vs. calling lte.disconnect()/dettach()[sic]/deinit()
-
Due to persistent troubles with LTE in Pycom boards detailed here, I am having to use a different and separate microcontroller to do my actual work, and externally power on/off a GPy/FiPy solely for LTE upload only.
- After a good upload, the typical lte.disconnect()/lte.dettach()/lte.deinit() sequence takes a solid 5 seconds
- It is much more efficient and power-sparing to simply power off the board before this, immediately after successful upload, rather than do the disconnect formalities and then power off the G/FiPy board
Are there any drawbacks/inefficiencies/dangers with not doing the formal closure before cutting power, but just getting it over with and cutting power to board immediately after successful upload?

You'll might have issue attaching to the network again, in which case you'll have to deinit and try re-attaching. Probably won't be an issue unless you save some state to nvram.
I don't understand the other part fully: Are you using all three commands to deinit the LTE modem? I think you only needlte.deinit()or the other two (although I'm looking for a definite answer to this as we speak).What do you estimate to power consumption difference to be? What power consumption/battery life do you need to achieve?
