our product must be able to be waken from sleep by receiving an SMS. This means, that the GSM module stays in standby mode active, even if the microcontroller sleeps.
We are afraid of losing the GSM connection in sleep. What happens in this case? Will the GSM module try to re-establish the GSM connection endlessly? In our application this would lead to the fast depletion of the capacity of the battery. Do you have any suggestion to avoid this case?
Thank you for your answer. This helps us.
