I need some help. I'm absolute new in the topic raspberry pi. I'm trying to connect the RPI3 with the SIM800 (https://www.itead.cc/wiki/RPI_SIM800_GSM/GPRS_ADD-ON_V2.0).
What I did:
- Connected the Raspberry with GSM Module Sim800 over the serials pins directly.
- Bought a new sim to send sms
- I already tried some comments from the post:Connect sim800 to Raspberry PI (RX, TX)
Whats my problem: If I try to run the code
import serial
import os, time
# Enable Serial Communication
port = serial.Serial('/dev/ttyS0', baudrate=9600, timeout=1)
# Transmitting AT Commands to the Modem
# '\r\n' indicates the Enter key
port.write('AT'+'\r\n')
rcv = port.read(10)
print rcv
I get a empty response. I also need to say that my Sim800 is searching for a network(according to the blinking LED)
Hopefully some of you can help me out with my problem.
Regards, Burner
