无法在API模式下使用Xbee发送/接收(python)
作者:互联网
我有两个Xbee Pro 900,每个都连接到Raspberry Pi.两者都更新到版本1061并设置为带启动的API启用.它们也具有相同的7FFF调制解调器VID.两个Pi都安装了PySerial和python-xbee库.
Xbee 1(接收器)的序列号为0013A200409A1BB8
Xbee 2(发件人)的序列号为0013A200709A1BE9
我在下面包含了我的代码,这只是我在网上找到的示例代码.我的问题是我没有在适当的Xbee上收到任何东西.我完全不知道出了什么问题,我已经三次检查目标地址和两个Xbee的配置设置.
Xbee 2代码(发件人):
#! /usr/bin/python
import time
from xbee import XBee
import serial
PORT = '/dev/ttyUSB0'
BAUD_RATE = 9600
# Open serial port
ser = serial.Serial(PORT, BAUD_RATE)
# Create API object
xbee = XBee(ser,escaped=True)
import pprint
pprint.pprint(xbee.api_commands)
DEST_ADDR_LONG = "\x00\x13\xA2\x00\x40\x9A\x1B\xB8"
# Continuously read and print packets
while True:
try:
print "send data"
xbee.tx_long_addr(frame='0x1', dest_addr=DEST_ADDR_LONG, data='AB')
time.sleep(1)
except KeyboardInterrupt:
break
ser.close()
Xbee 1代码(接收器):
#! /usr/bin/python
from xbee import XBee
import serial
PORT = '/dev/ttyUSB0'
BAUD_RATE = 9600
# Open serial port
ser = serial.Serial(PORT, BAUD_RATE)
# Create API object
xbee = XBee(ser,escaped=True)
# Continuously read and print packets
while True:
try:
print "waiting"
response = xbee.wait_read_frame()
print response
except KeyboardInterrupt:
break
ser.close()
当两个程序都在运行时,发送Xbee上的Tx指示灯闪烁,但我在接收Xbee上没有收到任何信息.有什么我想念的吗?谢谢你的时间!
解决方法:
您使用的是XBee还是XBeePro?我有同样的问题,this post给了我很多帮助.
尝试按以下方式修改Receiver Code:
import config
import serial
import time
from xbee import ZigBee
def toHex(s):
lst = []
for ch in s:
hv = hex(ord(ch)).replace('0x', '')
if len(hv) == 1:
hv = '0'+hv
hv = '0x' + hv
lst.append(hv)
def decodeReceivedFrame(data):
source_addr_long = toHex(data['source_addr_long'])
source_addr = toHex(data['source_addr'])
id = data['id']
samples = data['samples']
options = toHex(data['options'])
return [source_addr_long, source_addr, id, samples]
PORT = '/dev/ttyUSB0'
BAUD_RATE = 9600
# Open serial port
ser = serial.Serial(PORT, BAUD_RATE)
zb = ZigBee(ser, escaped = True)
while True:
try:
data = zb.wait_read_frame()
decodedData = decodeReceivedFrame(data)
print decodedData
except KeyboardInterrupt:
break
在我的情况下,上面的代码输出以下内容:
[['0x00', '0x13', '0xa2', '0x00', '0x40', '0x9b', '0xaf', '0x4e'], ['0x68', '0x3f'], 'rx_io_data_long_addr', [{'adc-0': 524}]]
Here我共享控制器节点的配置设置(与X-CTU兼容)
