A quick question re best practice, or perhaps least power draw when using the LoPy4, TTN and sleep.
Assuming my code needs to connects to TTN, read a temperature, upload result and then sleep for a few hours before waking and repeating…
Would it be considered acceptable to establish the TTN connection, then;
a) measure & upload
c) wake & repeat a),b),c)
or should the process be:
i) Connect to TTN
ii) measure & upload
iii) disconnect from TTN
v) wake & repeat i),ii),iii),iv),v)
As a test I left the machine doing a,b,c last night and today whilst on battery power and all worked fine… Just wondered if there was a better / more acceptable way with regards power, bandwith etc?
