Hi guys,
I am trying to execute a python script through Process.runShellCommand...
It does successfully executed but the script never return any data from doing:
while(p2.available())
{
output2 += (char)p2.read();
}
Serial.println(output2);
So the sketch is blocked by the script calling and it cannot continue to execute the following sentences.
Here I leave to you the sketch code (a part of it) and the python script code:
sketch.ino
Process p2;
p2.begin("/usr/bin/python");
p2.addParameter("/mnt/sda1/webexample/sendLogTempByMail.py");
//following parameters are some sensor temperature values
p2.addParameter("25.75");
p2.addParameter("25.00");
p2.addParameter("25.25");
p2.run();
String output2 = "";
while(p2.available())
{
output2 += (char)p2.read();
}
Serial.println(output2);
sendLogTempByMail.py
from datetime import datetime
import smtplib, sys
from email.mime.text import MIMEText
degree = u"\u2103"
USERNAME = "arturofelixchari@gmail.com"
PASSWORD = "mypasswd"
MAILTO = ''
with open('/mnt/sda1/webexample/admin_emails.config') as data:
datalines = (line.rstrip('\n') for line in data)
for line in datalines:
MAILTO += line
MAILTO += ', '
MAILTO = MAILTO[:-2]
msg = MIMEText('Temp. at S1 = '+str(sys.argv[1])+' '+degree.encode("utf-8")+'\nTemp. at S2 = '+str(sys.argv[2])+' '+degree.encode("utf-8")+'\nTemp. at S3 = '+str(sys.argv[3])+' '+degree.encode("utf-8"))
msg['Subject'] = 'TempLog ['+datetime.now().strftime('%Y-%m-%d %H:%M:%S')+']'
msg['From'] = USERNAME
msg['To'] = MAILTO
server = smtplib.SMTP('smtp.gmail.com:587')
server.ehlo_or_helo_if_needed()
server.starttls()
server.ehlo_or_helo_if_needed()
server.login(USERNAME,PASSWORD)
server.sendmail(USERNAME, MAILTO.split(","), msg.as_string())
server.quit()
Thanks in advance for any suggestion or correction,
Regards.
Arthur.
