In Target Monitoring Tool - using Commands \> Get Debug Infos \> Request EEPROM Logged Errors - I get:

```auto

3266.747	Trace	HLH	1	Except RTK ....21 0 31
3266.843	Trace	HLH	1	Except RTK ....21 0 31
```

So what is “Except RTK …21 0 31” ❓

This one doesn’t show up in any searches of the FAQ or the forum. ☹

Will Wavecom ever properly document this stuff? 😠

Well, I still don’t know what “RTK …21 0 31” specifically means, but the reason my app was crashing was due to an out-of-bounds array index.

So, I guess, “RTK …21 0 31” must be something to do with an invalid memory access…?

Hiya,

Just think yourself lucky that you can get any stored error codes out of your modules.

How did you enable this? I’ve tried and couldn’t get anything out.

I agree, it would be nice to know what the numbers/codes mean.

ciao, Dave
