leopard-c / as608 Goto Github PK

I correctly connect my GPIO pin to AS608, but i saw only ERROR! code=C7, desc=Setup failed! Please retry again later

At my arduino, AS608 perpectly works.

I saw test code in Arduino library, theres some different compare with example code.

This Repository's Example config file uses baud rate 9600, Arduino Example uses baudrate 57600.
At Arduino Example's README describe baudrate Sensor's UART baud rate (usually 57600, 9600 or 115200).

I recommend use baudrate 57600.

PLUS - Not Recommend, but usefull
If an permission error occurred when open serial device driver, use sudo chmod 666 <uart device driver>.
when sudo ./fp <command>, .fpconfig file will create at /root/.fpconfig

将AS608引脚TX、RX分别接在树莓派RX、TX引脚上，将AS608引脚VCC接在树莓派3.3V引脚上，以及将AS608引脚GND接在树莓派GND上之后，采用通讯协议，两者通信失败：

address=ffffffff
password=00000000
serial_file=/dev/ttyAMA0
baudrate=115200
detect_pin=1

请问如何解决这个问题呢
