About the interrupt handling of DW3120

Hi,
As the two stations of DW3120 approach each other from far and near,
RF signals have a transition zone from poor quality to good quality,
The program will enter the error callback function multiple times during this process,
The result is that DW3120 no longer updates the 40-bit counter,
What’s going on?
Thank you!

Hello @usb,

Which 40-bit counter are you referring to? The SYS_TIME value returned by the API (dwt_readsystime()), or a different timestamp register?

Hi, Akash
To track this error, we added a loop in the main loop to print . It appears that DW3120 is still responding to SPI queries, but it is no longer pulling up the interrupt line. It is unclear what state it is in.
