Firmware exception 0

[GIldons]

Hi!

I'm currently developing for the WFM200 and during testing, I ran into the issue below.

I first found this issue when periodically requesting the RSSI of my STA connection, and later on, I also got into the same error after hitting the WFM200 with heavier traffic. The second method however is less consistent than the first.

Here are some details of my setup: wfx-fullMAC-driver: v3.6.0 FreeRTOS AP and STA mode active at the time of exception STA connected. AP without clients

Hi,

It looks like you created the same case on Salesforce as well. Please confirm and if yes we'll focus on the discussion on Salesforce. Thanks.

Regards, Dzung.

No problem. I'll keep the updates via Salesforce.
