Linux/WL1837MOD: WL1837 Industrial critical application. hw self-diagnostic issue.

Tool/software: Linux

Hi dear Engineers.

Have an important question for Industrial ( critical ) application of WL1837.

The requirement is HIGH stability because it uses in PARKING LOT ( HANGs unacceptable ).

So, the Question about HOW TO recognize (use EXTRA diagnostic) possible abnormal state in case of WL1837 ? from my expierence,

1. sometimes AP mode is visible but not connectable (hw reset only helps)

2. same issue for BT hci

3. another BT device visible but not connectable (same, hw reset helps)

any experience will be usefull for us.

maybe connect Debug interface to our CPU to receive / log. data analyse ? maybe something elso.

Now in sales we use FN-LINK (Chinese Realtek) WiFi-BT Combo and we are often faced with several problems like full or partially hang state caused by EMC or some other (unknown) problems.

Thanks you!
