Why is the "GPRS Status" of the WAA library not always updated?

FAQ #101545

 

Symptom
In some projects where the PPP- and GPRS-diagnostic FBoxes of the Wide Area Automation library (WAA library) are used the following problem was observed:
After program download and setting the PCD to run, the FBoxes are active without any error but the output values of the FBox "GPRS diagnose" is 0 even if the modem is initialized:


Reason
The reason for this situation is that the FBox from the library version 2.6.150 has expected a "Clean All Elements" in order to correctly initialize.

Solution
Please update your WAA FBox library to version 2.6.151 or later and re-build / download your project. This FBox library version can be found on the support site.
In case it is not possible updating the FBox library, please execute a "Clean All Elements" before running the PCD (e.g. with the Online Debugger).

Remark
This FBox library version will be part of patch 2 for PG5 2.0.150.
