    ups the format text change any way open command 55 aa 01 00 00 00 00 00 01 00 01 01 send first: 55 sec; aa …. so on send last: 01

    ledOn 55 aa 01 01 00 00 00 00 12 00 13 01

    Hello, I used a microcontroller and I sent the bytes in the order that I supposed and I get the data that the module send to the microcontroller and I show the data in a LCD, so in I got it with that, how to send the byte. Be sure how format you recive the data, for exmaple I show the data like a caracter in a LCD and saw the data like a hex, so I send the data like caracter. (when I send the data like a HEX no work for me). Be sure the voltage for Tx and RX is 3.3 you can put a divisor in the out RX pin , the TX you can connect direct to the microcontroller (this if you working with 5 volts microcontroller)

    So you have to send the data like a little endian respresentation (LSB firt).

    for example, this the way to send a command packet (comand OPEN: 0x01). byte1:0x55 //tell is a command packet byte2:0xaa //tell is a command packet byte3:0x01 // device Id 0x00001 send firts the lsb BYTE: 01 byte4:0x00 // device Id 0x00001 byte5:0x00 // Parameter DWORD(if you want to send a parameter nozero send this bit with the value) byte6:0x00 // Parameter byte7:0x00 //Parameter byte8:0x00 //Parameter byte9:0x01 // comand word (OPEN: 0x0001) byte10:0x00 //comand byte11:0x01 //checksum word (sum each byte) 55+aa+01+1 : 0x0101 byte11:0x01 //checksum

    then you can send the others command like onLed () you will see the led on if you dont get a error

    byte1:0x55 //tell is a command packet byte2:0xaa //tell is a command packet byte3:0x01 // device Id 0x00001 send firts the lsb BYTE: 01 byte4:0x00 // device Id 0x00001 byte5:0x01 // Parameter DWORD (parameter nozero ledOn) byte6:0x00 // Parameter byte7:0x00 //Parameter byte8:0x00 //Parameter byte9:0x12 // comand word (CMOSLED: 0x0012) byte10:0x00 //comand byte11:0x13 //checksum word (sum each byte) 55+aa+1+1+12 : 0x0113 byte11:0x01 //checksum

    Other thing that maybe can help you, the command ispressFinger only work if the led is on(I dont know if always happen, but for me was like that).

    Sorry my english is not strong. greetings from Colombia.

No public wish lists :(
