NFC - ISO15693 - custom command

Hello,

Im trying to read data from an ISO15693 tag (M24LR64E-R from STMicroelectronics).

Im using react native and react-native-nfc-manager.

Here my code when I send customCommand:

Code Block     // init manager
    NfcManager.start()
    // waiting for a tag 
    let resp = await NfcManager.requestTechnology(tech, {  
        alertMessage: 'Ready to scan tag'  
    });
    let tag = awaitNfcManager.getTag();
    const handler = NfcManager.getIso15693HandlerIOS()
    const flags = Nfc15693RequestFlagIOS.HighDataRate
    const customCommandCode = 0xb3
    // some bytes
    const customRequestParameters = bytes.slice(2, bytes.length)
    // error with this cmd
    resp = await handler.customCommand({
      flags,
      customCommandCode,
      customRequestParameters
    })

Code Block
// init manager
NfcManager.start()

// waiting for a tag
let resp = await NfcManager.requestTechnology(tech, {
alertMessage: 'Ready to scan tag'
});

let tag = awaitNfcManager.getTag();

const handler = NfcManager.getIso15693HandlerIOS()

const flags = Nfc15693RequestFlagIOS.HighDataRate
const customCommandCode = 0xb3
// some bytes
const customRequestParameters = bytes.slice(2, bytes.length)

// error with this cmd
resp = await handler.customCommand({
flags,
customCommandCode,
customRequestParameters
})

But I receive this error (throw exception):

Code Block  [CoreNFC] 00000002 83601300 -[NFCTagReaderSession transceive:tagUpdate:error:]:710 Error Domain=NFCError Code=100 "Tag connection lost" UserInfo={NSLocalizedDescription=Tag connection lost}

Code Block
[CoreNFC] 00000002 83601300 -[NFCTagReaderSession transceive:tagUpdate:error:]:710 Error Domain=NFCError Code=100 "Tag connection lost" UserInfo={NSLocalizedDescription=Tag connection lost}

Do you know why connection was lost ?
