GPRS Data send week time schedule (ID=272)
This parameter manages when it is allowed to open GPRS context. When module starts it is
prohibited to open the context. When modem‟s GPRS context is being closed (for example changing
network) it is allowed to open it only at defined time. It is possible to allow connections every 10
minutes up to once per day.
Example value: 7FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
Format is described in the next chapter.
SMS Data send week time schedule (ID=273)
Parameter defines SMS data sending according to week time schedule. This parameter is used
to set data sending on selected week days and hours. Minimum time step is 10 minutes.
Example value: 7FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF
Schedule parameter format
Time is defined as 20 byte array. First byte of array defines week days, the following 18 bytes
define timestamps with 10 minute interval and the last byte is unused. In first byte, first bit (LSB)
defines if module should connect to GPRS (send SMS) on Monday, second bit – on Tuesday and so
on up to seventh bit – which means Sunday. Eighth bit (MSB) is not used. If bits value is 0 then device
is not allowed to open GPRS context, but if it is already open – does not close it. If value is 1 it will
work as day minutes are defined in rest of the bytes.
Day‟s minutes are defined by 18 bytes (144 bits). Every n‟th bit (beginning from the first bit
(LSB) and ending 18 bytes 8‟th bit (MSB)) indicates every 10‟th minute of the day (day has 1440
minutes).
Example:
GPRS will be allowed on Monday to Friday at 8:00 and 16:00 GMT the following value should
be configured:
00011111
00000000 00000000 00000000 000000000 00000000 00000000 0000000

00000000 00000000 00000000 00000000 00000000
Red bits indicate that GPRS will be allowed everyday except Saturdays and Sundays. Blue bits
indicate 480 and 720 minutes (480 min = 8 h and 720 min = 16 h). So the parameter value should be:
1F 00 00 00 00 00 00 01 00 00 00 00 00 01 00 00 00 00 00
It should be sent as UTF8 encoded string.
SMS Data send allow (ID=250)
Parameter allows or does not allow using binary SMS to send Avl data. If SMS use is not
allowed value is 0, and 1 if allowed.
