NFC communication error due to PH_ERR_COLLISION_ERROR

[VasuVirpariya]

We are using PN7462 to read the type2 tag. We successfully establish the connection between them. We are reading tags at every 500ms. However, after approximately 2-3 minutes, we noticed that the connection was lost. After we debugged we discovered that the hal library for PN7462 returned a collision error(PH_ERR_COLLISION_ERROR).

What could be the cause of this error?

It was a hardware issue.

Hello, my name is Fabian, I've been assigned to support your case.
I appreciate your interest in our products.
Could you please clarify which example are you using and, if the application isn't causing a failure in the memory of the PN7462 or, creating some sort of bottleneck in the respective controller?
I have to highly recommend that you take a look at the memory management since, these are examples for testing purposes and to show how the API is used but, I'm sure there is a lot of improvement room.
