µFR Nano Online Reader implementation basics #
This section will describe how to use the µFR Nano Online reader.
UDP/TCP communication #
- All bytes sent to UDP/TCP port 1 will be forwarded to UART1 and vice versa
- All bytes sent to UDP/TCP port 2 will be forwarded to UART2 and vice versa
- µFR Series libraries have support for UDP/TCP communication
- UDP/TCP mode works in parallel with Transparent and HTTP mode.
UDP/TCP communication – Reader opening example #
/*
Opening reader on IP address 192.168.1.112 and port 8881 for UDP communication. */
ReaderOpenEx(0, “192.168.1.112:8881”, ‘U’, 0);
/*
Opening the reader on IP address 192.168.1.112 and port 8881 for TCP communication. */
ReaderOpenEx(0, “192.168.1.112:8881”, ‘T’, 0);
BLE serial mode communication #
- All bytes sent to the BLE serial port will be forwarded to UART1 or UART2 and vice versa.
- BLE mode doesn’t work in parallel with UDP/TCP and HTTP mode.
BLE serial mode communication – Reader opening example #
/*
Opening reader in BLE serial mode on virtual port COM34. Must disable reset on opening. */
ReaderOpenEx(2, “COM34”, 0, “UNIT_OPEN_RESET_DISABLE”);
BLE serial mode communication #
- All bytes sent to the USB serial port will be forwarded to UART1 or UART2 and vice versa.
- The transparent mode works in parallel with UDP/TCP and HTTP mode.
Transparent mode communication – Reader opening example #
/*
Opening the reader in Transparent mode. Must disable reset on opening.
*/
ReaderOpenEx(2, 0, 0, “UNIT_OPEN_RESET_DISABLE”);
HTTP mode communication #
- All HEX string bytes sent in POST body will be forwarded to UART1 or UART2 and vice versa.
- HTTP mode works in parallel with UDP/TCP and Transparent mode.
HTTP mode communication – GetCardIdEx example #
/*
Getting Card ID in HTTP mode using an HTTP POST request.
*/
HTTP POST Request body sent to µFR Reader /uart1 or /uart2 > 557caa00aaccec
HTTP POST Response body sent from µFR Reader > de7ced0b08044f52dad995000000000000cb
