I’m working on some factory testing for our WP85 based boards.
So far I’ve implemented some testing around sensor readings and digital inputs/outputs, but I’m looking to expand this testing to the hardware within the WP85 itself (in particular, cell modem and GPS). An example of this is a WCDMA failure we’ve seen on ~3 of our units, so it would be useful to have tests in place to catch this failure.
Has anyone defined a list of AT commands that could potentially catch something like this in a factory? I’ve had a look through the AT command reference for the WP85 but couldn’t really find what I was looking for.
Any guidance is greatly appreciated.
