Unfortunately, there is no time (and equipment anymore) to maintain this repository. I hope that someone else will find the time to continue with that.
With gsmHat, you can easily use the functionality of the Waveshare GSM/GPRS/GNSS HAT for Raspberry Pi (Link to HAT). On this module a SIM868 Controller is doing the job to connect your Raspberry Pi with the world just by using a sim card.
👉 Internet functionality added!
gsmHat was written for Python 3. It provides the following features
- Non-blocking receiving and sending SMS in background
- Non-blocking calling
- Non-blocking refreshing of actual gps position
- Non-blocking URL Call and receiving of response
In the following paragraphs, I am going to describe how you can get and use gsmHat for your own projects.
To download gsmHat, either fork this github repo or simply use Pypi via pip.
$ python3 -m pip install -U gsmHat-
Install your sim card in your module, connect the GSM and the GPS antennas and mount the module on the pin headers of your Raspberry Pi. Make sure, that you do not need to enter Pin Code to use your card. Pin Codes are not supported yet.
-
Enable the Uart Interface in your Raspberry Pi
- Start raspi-config:
sudo raspi-config. - Select option 5 - interfacing options.
- Select option P6 - serial.
- At the prompt
Would you like a login shell to be accessible over serial?answer 'No' - At the prompt
Would you like the serial port hardware to be enabled?answer 'Yes' - Exit raspi-config and reboot the Pi for changes to take effect.
- Start raspi-config:
- Import gsmHat to your project
from gsmHat import GSMHat, SMS, GPS- Init gsmHat
gsm = GSMHat('/dev/ttyS0', 115200)- Check, if new SMS are available in your main loop
# Check, if new SMS is available
if gsm.SMS_available() > 0:
# Get new SMS
newSMS = gsm.SMS_read()
# Do something with it- Do something with your newly received SMS
# Get new SMS
newSMS = gsm.SMS_read()
print('Got new SMS from number %s' % newSMS.Sender)
print('It was received at %s' % newSMS.Date)
print('The message is: %s' % newSMS.Message)- You can also write SMS
Number = '+491601234567'
Message = 'Hello mobile world'
# Send SMS
gsm.SMS_write(Number, Message)- Or you can call a number
Number = '+491601234567'
gsm.Call(Number) # This call hangs up automatically after 15 seconds
time.sleep(10) # Wait 10 seconds ...
gsm.HangUp() # Or you can HangUp by yourself earlier
gsm.Call(Number, 60) # Or lets change the timeout to 60 seconds. This call hangs up automatically after 60 seconds- Lets see, where your Raspberry Pi (in a car or on a motocycle or on a cat?) is positioned on earth
# Get actual GPS position
GPSObj = gsm.GetActualGPS()
# Lets print some values
print('GNSS_status: %s' % str(GPSObj.GNSS_status))
print('Fix_status: %s' % str(GPSObj.Fix_status))
print('UTC: %s' % str(GPSObj.UTC))
print('Latitude: %s' % str(GPSObj.Latitude))
print('Longitude: %s' % str(GPSObj.Longitude))
print('Altitude: %s' % str(GPSObj.Altitude))
print('Speed: %s' % str(GPSObj.Speed))
print('Course: %s' % str(GPSObj.Course))
print('HDOP: %s' % str(GPSObj.HDOP))
print('PDOP: %s' % str(GPSObj.PDOP))
print('VDOP: %s' % str(GPSObj.VDOP))
print('GPS_satellites: %s' % str(GPSObj.GPS_satellites))
print('GNSS_satellites: %s' % str(GPSObj.GNSS_satellites))
print('Signal: %s' % str(GPSObj.Signal))- Calculate the distance between two Points on earth
GPSObj1 = GPS() # You can also use gsm.GetActualGPS() to get an GPS object
GPSObj1.Latitude = 52.266949 # Location of Braunschweig, Germany
GPSObj1.Longitude = 10.524822
GPSObj2 = GPS()
GPSObj2.Latitude = 36.720005 # Location of Manavgat, Turkey
GPSObj2.Longitude = 31.546094
print('Distance from Braunschweig to Manavgat in metres:')
print(GPS.CalculateDeltaP(GPSObj1, GPSObj2)) # this will print 2384660.7 metres- Call URL to send some data
# Init gsmHat
gsm = GSMHat('/dev/ttyS0', 115200)
# Set the APN Connection data. You will get this from your provider
# e.g. German Provider 'Congstar'
gsm.SetGPRSconnection('internet.telekom', 'congstar', 'cs')
# Get actual GPS position
GPSObj = gsm.GetActualGPS()
# Build url string with data
url = 'www.someserver.de/myscript.php'
url += '?time='+str(int(GPSObj.UTC.timestamp()))
url += '&lat='+str(GPSObj.Latitude)
url += '&lon='+str(GPSObj.Longitude)
url += '&alt='+str(GPSObj.Altitude)
gsm.CallUrl(url) # Send actual position to a webserver- Get the Response from a previous URL call
# Check, if new Response Data is available
if gsm.UrlResponse_available() > 0:
# Read the Response
newResponse = gsm.UrlResponse_read()
# Do something with it- More options to configure the module (e.g. using sim cards with pin code)
