Testing; At Command Entry Timing Requirement; Acceptance Testing; Test Requirements - Sierra Wireless MC5725 Hardware Integration Manual

8: Testing

Note: Acceptance testing is
typically performed for each
shipment received.
Rev 1.9.1 Feb.09
In the event of a discrepancy in values between this guide and the Product Specification Document (PSD), the PSD takes precedence.
Note: All Sierra Wireless embedded modules are factory-tested to
ensure they conform to published product specifications.
Developers of OEM devices integrating Sierra Wireless
modules should include a series of test phases in their
manufacturing process to make sure that their devices work
properly with the embedded modules.
Suggested phases include:

Acceptance testing

•
received from Sierra Wireless
Certification testing
•
required certifications before beginning mass production
Production testing
—testing of completed devices with the
•
modules embedded
Quality assurance testing
•

AT command entry timing requirement

Some commands require time to process before additional
commands are entered. For example, the modem will return
"OK" when it receives AT!DAFTMACT. If AT!DASBAND is
received too soon after this, the modem will return an error.
When building automated test scripts, ensure that sufficient
delays are embedded where necessary to avoid these errors.
Acceptance testing
When you receive a shipment from Sierra Wireless, you should
make sure it is suitable before beginning production.
From a random sampling of units, test that:
• The units are operational
The units are loaded with the correct firmware version
•

Test requirements

To perform the suggested tests, you require a test system in
which to temporarily install the module, and you must be able
to observe the test device's LED indicator.
