Hi everybody,

I wonder if EC21E module has capability of jamming detection.
I didn’t found any AT command for it. If it exists, can you please provide the document?

Side question: if jam detection is available, is it supported in QuecOpen?

Thanks and regards

Hello @Puck-Q,
For “jamming” I mean the capability to detect if strong interference are received such that it prevents good communication and registration to network.

Thanks
