Hello,

Could you please help me with more details? Which examples are you running? I assume you are using one of the connectivity ones as you mention the disconnections.

As there are no development kits for the QN9083 , I assume you are using your custom board, is that correct?

When debugging, which it's the last event or line of code executed before you get the hardfault?

Regards ,

Hello,

The part of the code you mention, is it of your own application? Did you add it to the code, I need more context, where are you calling it? In which function or task?

Do you have more details on it? Could you please share some sniffer log that might help me to see how are you sending the frames and which error are you getting?

Hello,

Maybe you are overwriting some kind of buffer or information needed, overlapping or need more pools sections.I still need more details, on where and how are you calling it .
