pass
if ( re.search(b'OK',line)):
break
def sendAT_Cmd(serInstance,atCmdStr):
serInstance.write(atCmdStr.encode('utf-8'))
wait_for_cmd_OK()
ser = serial.Serial("/dev/ttyACM0",9600,timeout=30) # Select the serial number and baud rate because I am ubuntu The serial number is /dev/ttyACM0
sendAT_Cmd(ser,'AT+CFUN=1\r')
ser.close()
