Hi Kevin,
thank you very much for your quick reply.
We'll as I said we are just in the same stage as you did in the past. However we are using Kotlin and Javas SmartCard API. The readers were using are the ACS ACR122U and the ACS ACR 1222L which both use the PN532. The good thing is these readers provide a pseudo APDU to directly communicate with the PN532.
We're currently trying to put the tag to sleep and reactivate it in order to enable ISO14443-4 layer. However we're not sure which commands of the PN532 we should use in order to achieve this. We're using the InRelease command and the InAutoPoll. For layer 4 communication we successfully use the InDataExchange command and as I said we have completely implemented SL3 authentication, reading and writing. We're only stuck with the SL1 to SL3 switching.
(https://www.nxp.com/docs/en/user-guide/141520.pdf page 65-66 contains a list of the PN532 commands)
Any help is very much appreciated and once again thank you very much.
