Hello

I use NXP PN7150. It works correctly but in this specific situation not.

I try restart my discovery loop with NxpNci_StartDiscovery() some seconds after I called NxpNci_StopDiscovery().

NxpNci_StartDiscovery() return an error.

Do you have a suggestion or have you ever had this problem?

Thanks for your help.

Regards,

phlb.
