Expiry of the transmission cycle if the "Interval" connection type was selected (see "Basic
setting" on page 53)
1. The myDatalogNANOamr checks whether any errors occurred during the last login attempt.
No errors:
The myDatalogNANOamr logs into the same GSM network that was also used last time.
Error:
Continue with the next step
Note: A transmission error is not the same as an error that occurs when logging into
the GSM network. It is possible for the login to the GSM network to work correctly but
that a transmission error still occurs.
The following steps are only completed if an error was detected during step 1:
2. The device searches for GSM networks within its receiving range and creates a list of available
GSM networks.
3. A search of the list of available GSM networks is completed and the first GSM network is
selected that is not on the "ban list" and is assigned to one of the service providers
supported by the integrated SIM chip (see www.microtronics.at/footprint).
Note: An explanation detailing the conditions when a GSM network is added to the "ban list" is provided in
"Ban list" on page 24.
5.2.1 Ban list
The ban list provides space for 5 entries and is not saved in a volatile memory. This means that it is
also available following a PowerOn.
If a "BEARER GPRS FAILED" error occurs (see "Modem error" on page 117), an internal counter is
increased by 2 . If the transmission was completed without errors, i.e. all of the data was transferred,
this internal counter is reduced by 1 . The current GSM network is added to the ban list if the internal
counter reaches the value 6 .
The ban list is deleted if no GSM network can be selected from the list of available GSM networks in
the receiving range taking the ban list into consideration. Another search for GSM networks in the
coverage area is completed once the ban list is deleted and the network selection is completed with
the ban list that is now empty (see item 3 in the chapter"Selection of the GSM network" on page
23).
