number of retries is considered as transmission failure and sets
triggering input FS1_gprs 0--> 1, that can be used for Rules
processing (SMS sending). As a consequence, after elapsing of
time defined in Wait time after disconnection, the module
performs RESET and commences GSM/GPRS login sequence.
Reduction of this parameter increases the frequency of testing
GPRS network state. This shortens possible disruptions of
control due to network failures but increases "unproductive"
data transmission.
7.2.3.9. GPRS testing IP address
Function
-
sets IP address where data frames testing GPRS network state
are sent.
Data type
- IP
address
field
Range
-
0.0.0.0 - 255.255.255.255
Default value
- 0.0.0.0
Comments
-
This parameter sets recipient's address for data frames testing
GPRS transmission channel sent after defined Idle time elapses.
Leaving recipient address at
0.0.0.0
sends data frames to
module's own IP address. Any other valid address (within the
APN) is accepted as the recipient.
7.2.3.10. Number of login retries
Function
-
Defines max. number of login to GPRS network retries. Each
unsuccessful attempt changes the state of triggering input
FS1_gprs from '0' to '1' and increases the failure counter by 1.
After reaching declared value the module displays error code
and awaits user action.
Successful login resets failure counter.
Data type
- number
Range
- 0…255
Default value
- 0
Comments
-
Setting the value to "
0
" results in endless retries
7.2.3.11. Wait time after disconnection
Function
-
Defines interval (in seconds) before resuming after failed login
attempt.
Data type
- number
Range
- 0…60
[s]
Default value
- 5
[s]
Comments
-
Setting the value to
0
results in immediate retries.
7.2.3.12. Data frame format
Function
-
This parameter selects data frame type used by module for
GPRS communication, and indirectly the operating mode.
