Is the Particle.keepAlive() function needed in automatic mode? Can someone advise me on the most reliable way to deploy an electron longterm without losing connectivity?
In our application the device will be charged via solar panel. I have noticed that if the battery pack drops below 2.7 volts the undervoltage lockout kicks in and powers down the device. If the battery charges back up to say 2.75 - 2.8 V the electron powers up but fails to reconnect and goes to listening mode. This puts us in a state that is not desirable.
The best thing to do is never get in this situation so we will oversize the battery and solar panel. However, if it did happen I would like to recover i.e, wait for the voltage to reach 3.3V before reconnecting.
Can someone suggest using Automatic, Semi-Automatic, or Manual modes to accomplish a robust link?
