- modified method to sending SMS a JSON data messages:
a) If there is some request to send JSON or SMS
Modem starts and tries to find mobile signal and check its level. If signal is
not detected, modem turns off and waits
–
an idle time for next connection
attempt is increased dynamically. It means modem, after unsuccessful
mobile network signal detection, will try to connect again after 10 s, 30 s,
1 min, 5 min, 10 min, 30 min, 1 hour, 3 hours, 6 hours, 12 hours (till now was
waiting 30s repeatedly). It will save the battery energy if there is no signal
available. If an external power is available, then waiting interval is extended
to 10 min max. When new event requesting to send SMS or JSON data
occur, modem once tries to start immediately. If it fails again, previous delay
is restored again.
b) When modem tries to send SMS
If it is not possible to send SMS to pre-set phone number (network signal is
available already), it will repeat it 3 times. If still not possible to send SMS,
SMS will be deleted, and this situation will be marked into device's record.
c) When modem tries to send JSON data
Under normal conditions when there is necessary to send the data, modem
is switched on, logged to mobile network, connected to server and transfers
JSON data. But when mobile network or receiving server is temporary
unavailable, then the data cannot be send immediately. If some error during
data sending occurs, logger tries to resend it twice again immediately. If it
still fails, JSON message stays stored into internal buffer (if free space is
