python - 多行输出到一个命令
问题描述
我面临着有趣的问题。我需要每秒调用（几次）来自 RPi-Hat 的 GPS 信息。如果我一次调用请求，就一切正常。但是，如果我开始循环命令，那么来自 Hat 的响应会变得越来越大，并且在某一时刻我遇到了一个写入错误：serial.serialutil.SerialException: write failed: [Errno 5] Input/output error. 我认为问题是由来自 Hat 响应的数据量引起的。
我现在的问题是：一个电话我如何只得到一条响应。显然我不需要在一个数据块中回答 30 次。
代码如下所示：
#!/usr/bin/python
# -*- coding:utf-8 -*-
import RPi.GPIO as GPIO

ser = serial.Serial('/dev/ttyS0',115200)
ser.reset_input_buffer()

time_count = 0
def send_at(command,timeout):
rec_buff = ''
ser.write((command+('\n')).encode('utf-8'))
time.sleep(timeout)
if ser.in_waiting:
time.sleep(0.01)
rec_buff = ser.read(ser.in_waiting)
print(rec_buff)

print('---------------------------------------------')
time.sleep(2)
send_at('AT+CGPS=1,1', 1)
#ser.flush()
ser.reset_input_buffer()
ser.reset_output_buffer()
while i <20:
if ser.writable():
print('AT+CGPSINFO')
print('---------------------------------------------')
time.sleep(2)
send_at('AT+CGPSINFO', 1)
#ser.flush()

输出如下所示：
